  • Adaptability and stability analysis of groundnut genotypes using AMMI
           model and GGE-biplot
    • Authors: Amare Kebede B; Adisu Getahun
      Pages: 343 - 349
      Abstract: Unpredictable rainfall, variations in farm inputs, crop-diseases, and the inherent potential of genotypes are among the major factors for low and variable crop yield. Fourteen elite groundnut genotypes were examined in 14 environments to analyze adaptability and stability of genotypes, and identify mega-environments if they exist. Additive main effect and multiplicative interaction (AMMI) model, cultivar-superiority measure, and genotype plus genotype-by-environment (GGE) biplot analysis were used for data analysis. The environment (69.8%) and genotype-by-environment interaction (GEI) effects (21.4%) were dominating the genotypic effect (8.8%). The GEI was significant (P < 0.01), and two distinct environments (mega-environments) were identified, suggesting separate national groundnut breeding strategies for Babile and Pawe. ICGV-94100 and ICGV-97156 were stable and had the highest-yield at Babile and Pawe, respectively. The higher heritability value was recorded in more homogeneous and favorable environments, indicating the genetic potential of groundnut genotypes were better attained in more homogeneous and favorable environments. AMMI model, cultivar-superiority measure, and GGE biplots were helpful methodologies and complemented each other to evaluate the adaptability and stability of groundnut genotypes in diverse environments.

  • Functional diversity of RING E3 ligases of major cereal crops in response
           to abiotic stresses
    • Authors: Sandeep Chapagain; Yong Chan Park; Cheol Seong Jang
      Pages: 351 - 357
      Abstract: Abiotic stresses significantly reduce the grain yield and productivity of cereal crops, especially rice, and this may affect food security in the future. Different abiotic stress adaptation pathways have been investigated and depicted in plants. Among these, the ubiquitin-proteasome system (UPS) has been studied as a key mechanism to understand the protein regulation pathways that enhance the adaptation and survival of plants under various environmental stresses such as drought, salinity, cold, and toxic metalloid exposure. RING E3 ligases constitute a highly diverse and important enzyme group that acts within the 26S UPS, and it also plays a crucial role as a central regulator of plant physiological and cellular processes. This review aimed to highlight recent findings and discoveries regarding the different stress-induced RING E3 ligase genes of major cereal crops and their functions via ubiquitination pathways under different environmental stress conditions. Such genes regulate different physiological responses including protein stabilization, cell membrane integrity, regulation of stomatal opening, and the maintenance of meristematic cells, and they also regulate reactive oxygen species and heavy metal levels via ubiquitination in plants. Hence, the ubiquitination process is considered a potential target for the development of abiotic stress-tolerant crops, and it might be used as an excellent mechanism for stress-tolerant crop improvement programs.

  • Hijacking tobacco hairy roots and leaves in order to produce IpaD antigen
           by means of different signal peptides
    • Authors: Shahram Shokrian Hajibehzad; Fariba Abooei Mehrizi; Hossein Honari; Houshang Alizadeh
      Pages: 359 - 368
      Abstract: IpaA, IpaB, IpaC, and IpaD are Shigella dysenteriae Ipa operon genes which collectively contribute in invasion to the epithelial cells of the human gut. Among them, IpaD has been demonstrated to play the most crucial role in shigellosis. Noteworthy, due to the more efficient, cost-effective and no need for advanced equipment in comparison with traditional systems, plant-based expression systems are considered as a novel strategy for production of recombinant proteins. As an aim of this research, attempts were carried out to examine and compare IpaD antigen production in three different plant-based platforms, including transgenic tobacco hairy roots and leaves as well as a transient based expression. Furthermore, different signal peptides (i.e. Zera® and Extensin) were also employed in order to improve the production level. Based on TAS-ELISA result, the highest yield of IpaD acquired by ER-derived protein bodies (Zera® ) which was more than 1.29-fold higher as compared with apoplastic space based on TSP% in both transgenic tobacco hairy roots and leaves. Furthermore, transgenic tobacco hairy roots were more abundant than transgenic leaves averaging 0.52 ng of IpaD per μg TSP and with a maximum of 0.94 ng IpaD per μg TSP in the best-performing construct of pBI-ZeCIpaD. Totally, the results of quantitative RT-PCR and TAS-ELISA indicated that the best time point for the production of IpaD using agroinfiltration was 72 h post infiltration and during 72 to 96 hpi, expression levels descended rapidly. To the best of our knowledge, this is the first report representing and combining the potential effects of signal peptides and plant-based expression platforms on stably production of IpaD antigen in transgenic tobacco leaves and hairy roots.

  • Identification and validation of cold responsive microRNAs of Hevea
           brasiliensis using high throughput sequencing
    • Authors: Linu Kuruvilla; MB Mohamed Sathik; Molly Thomas; Lisha.P Luke; Sumesh KV
      Pages: 369 - 377
      Abstract: Cold stress is one of the major abiotic factors that influence the productivity and geographical distribution of many agriculturally important crops like Hevea brasiliensis. Cultivation of H. brasiliensis in India is being extended to northeastern regions, where low temperature during winter adversely affects its survival, growth, and productivity. Developing cold-tolerant genotypes is a primary requisite to maximize the productivity under such challenging environmental conditions. However, lack of methods for early evaluation of cold tolerance in the newly developed clones and the extensive time required for assessing their tolerance in the field are major constraints for clonal selection. The present study was initiated with an objective to identify and characterize cold stress responsive miRNAs from H. brasiliensis that show stronger association with cold tolerance. Next generation sequencing using Illumina HiSeq method revealed the expression of 21 and 29 conserved miRNA (from clone RRIM 600) families in cold-stressed and control samples, respectively. Forty-two novel miRNAs were identified from this study. Upon differential expression analysis, eight conserved miRNAs were found commonly expressed in both the samples. When expression analyses were performed subsequently with six selected miRNAs in two Hevea clones (viz. RRII 105 and RRIM 600), miR169 showed a strong association with cold tolerance. miRNAs such as miR482 and miR159 also exhibited association with cold tolerance. This study suggests the possibility of employing these miRNAs as markers for cold tolerance after validation in more number of genotypes with varying levels of cold tolerance.

  • Early generation genetic variation and heritability of yield and related
           traits among tef populations
    • Authors: Mizan Tesfay Abraha; Shimelis Hussein; Mark Laing; Kebebew Assefa
      Pages: 379 - 386
      Abstract: The extent of genetic variation and heritability of a trait are among the major determinants of selection gains in plant breeding programs. The aim of this study was to determine the magnitude of genetic variation and inheritance of grain yield, and component traits of newly developed tef populations under moisture-stressed and non-stressed conditions for drought tolerance breeding. Seventeen crosses along with the parents were evaluated in the F2 generation under moisture-stressed and non-stressed conditions in northern Ethiopia during 2015 and 2016. There were marked genotypic and phenotypic variation among the crosses in the F2 generation for plant height, panicle length, peduncle length, number of productive tillers per plant, main shoot panicle seed weight, biomass yield, and grain yield under both test conditions, important for successful selection and genetic advancement. The families of DZ-Cr-387 x 207832 and DZ-Cr-387 x 222076 were high grain yielders with early maturity under both test conditions.

  • Allelic composition and associated quality traits of the Glu-1 and Glu-3
           loci in selected modern Ethiopian durum wheat varieties
    • Authors: Daniel Hailegiorgis; Chong Ae Lee; Song Joong Yun
      Pages: 387 - 392
      Abstract: Gluten protein determines the processing quality of both durum wheat and bread wheat. The glutenin subunits compositions and associated quality traits of 20 Ethiopian durum wheat varieties were systematically analyzed using SDS-PAGE and Payne numbers. A total of 16 glutenin patterns were identified. At the Glu-A1 locus, all varieties scored the null allele. The predominant glutenin alleles at the Glu-B1 locus were Glu-B1b (7+8) and Glu-B1e (20). In Glu-3, the most abundant glutenin subunits were Glu-A3a and Glu-B3c. Based on the Payne scores, the varieties Yerer, Ginchi, Candate, and Foka were identified to have allelic composition suitable for pasta making. The cluster analysis using agglomerative hierarchical clustering (AHC) method classified the varieties into four similarity classes. Based on the findings of this experiment, suggestions were made for allelic composition improvement through introgression of superior alleles from known Glu-1 and Glu-3 sources.

  • Unveilingsources of stripe rust resistance in diverse wheat ( Triticum
           Aestivum L.) germplasm using narrow down methodology: a proof of concept
    • Authors: Saurabh Badoni; Reeku Chaudhary; Ravi Shekhar; Shweta Badoni; Ekhlaque Ahmad; Rishi Pal Gangwar; Kashi Nath Tiwari; Rajendra Singh Rawat; Deepshikha; Jai Prakash Jaiswal
      Pages: 393 - 403
      Abstract: Stripe rust of wheat caused by the fungal pathogen is a destructive foliar disease of wheat. Thus, it is crucial step to characterize the resistant germplasm for stripe rust in a diverse germplasm pool for their ultimate utilization in efficient crop rust resistance breeding. In the present study, we followed two pronged strategies involving integrated phenotypic and molecular characterization of 440 diverse wheat germplasm lines for rust resistance. The germplasm panel was extensively evaluated in field epiphytotic conditions during two consecutive years. After rigorous screening, 72 accessions were successfully revealed as resistant to moderately resistant to stripe rust. Subsequently, entries were then evaluated for their field agronomicperformances, considering prerequisites for serving as a donor germplasm,particularly for yield and 33 potential rust-resistant accessions were identified. Furthermore, to detect the sources of resistance, accessions were molecular characterized for potential race-specific resistance genes Yr5, Yr10,Yr15, and effective adult plant resistance (APR) gene Lr34/Yr18/pm38. We identified the 22 accessions possessing one or more single resistance genes and two accessions were observed with at least three of them. Moreover, Lr34/Yr18/pm38 was determined to confer resistance when observed along with any of the race-specific genes. Thus, the study not only provides proof of concept methodology to identify candidate resistant sources from large germplasm collections but simultaneouslyconfirmed the contribution of combining race-specific andnon-specific APR genes. The finding could further assist in the potential deployment of resistant genes directly into the stripe rust breeding program by involving marker-assisted approaches.

  • High frequency shoot proliferation from cotyledonary node of Lawsonia
           inermis L. and validation of their molecular finger printing
    • Authors: Arpita Moharana; Aradhana Das; Enketeswara Subudhi; Soumendra K. Naik; Durga P. Barik
      Pages: 405 - 416
      Abstract: An efficient and reproducible protocol for in vitro plant regeneration was developed for Lawsonia inermis L. using cotyledonary node explant derived from axenic seedlings. Highest shoot proliferation frequency (ca 96.6%) was achieved on Murashige and Skoog’s, 1962 (MS) basal medium supplemented with 8.88 μM 6-Benzyladenine (BA) + 2.68 μM Napthalene acetic acid (NAA). Up-scaling of shoots was carried out using in vitro nodes on MS medium supplemented with 4.44 μM BA. So overall, an average of 238 shoots was produced at 75 days. Of the four different forms of cotyledonary node explants evaluated, highest shoot multiplication was observed in cotyledonary node explant with two whole cotyledons. In vitro regenerated shoots were best rooted (ca 34.3 roots / shoot) on ½ MS medium devoid of any growth regulator. The plantlets were successfully acclimated in sand:soil:: 1:1and established in the garden soil. Random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analysis revealed a homogeneous amplification profile for all micropropagated plants validating the genetic fidelity of the in vitro-regenerated plants and supporting the regeneration protocol for economic commercial exploitation.

  • Geospatial delineation of South Korea for adjusted barley cultivation
           under changing climate
    • Authors: Han-Yong Kim; Jonghan Ko; Seungtaek Jeong; Jun-Hwan Kim; Byunwoo Lee
      Pages: 417 - 427
      Abstract: Determining effective measures to alleviate the impact of climate change on crops under various regional environments is one of the most urgent issues facing agriculture. In this study, geographic regions of South Korea for future-adjusted barley cultivation were outlined and the impact of climate change on barley production in the next 100 years was evaluated under two greenhouse gas concentration trajectory scenarios: the representative concentration pathway (RCP) 4.5 and RCP 8.5. To achieve our intended study goals, a geospatial crop simulation modeling (GCSM) scheme was formulated using CERES-barley model of Decision Support System for Agricultural Technology (DSSAT) crop model package version 4.6 to simulate grid-based geospatial crop yields. Two experiments were carried out at an open field to obtain model coefficients for the nation and at temperature gradient field chambers to evaluate the performance of the CERES-barley model under elevated temperature conditions. Suitable cultivation regions for three different types of barley (naked, hooded, and malting) under changing climate were projected to expand to the northern regions under both RCP 8.5 and RCP 4.5. However, they were projected to expand more rapidly under RCP 8.5 than those under RCP 4.5. Projected yields of four barley varieties were increased with a slow phase as year progressed under RCP 4.5 scenario. However, they were rapidly increased under RCP 8.5 scenario. It appears that geospatial variation in barley yield under changing climate can be effectively outlined. Therefore, GCSM system might be useful for determining impacts of climate change on geospatial variations of crops, potentially providing means to impede food insecurity.

      Abstract: Soybean is known to be intolerant of waterlogged conditions. Flooding stress usually affects the crop via poor and retorted root development. The current study aimed to isolate indole acetic acid (IAA)-producing bacteria with potential to induce adventitious root growth and counteract flooding stress. The isolate AY-13 was identified as Klebsiella variicola using 16S DNA sequencing and phylogenetic analysis. A pure culture of AY-13 Klebsiella variicola was subjected to chromatography and mass spectrometry selected-ion monitoring (GC-MS/SIM) for IAA quantification. The results revealed the presence of (84.27±3.55 μg/mL) IAA in the AY-13 culture. The strain AY-13 was able to induce adventitious root initiation. Therefore, soybean seedlings were inoculated with AY-13 to examine its potential for promoting growth and reprograming after flooding stress. AY-13 application not only mitigated the flooding stress, but also significantly improved the plants’ growth, enhanced chlorophyll contents, and improved the quantum efficiency of chlorophyll fluorescence during and after flooding stress. Our findings were that AY-13 possesses great potential for mitigating flooding stress and improving soybean plant growth.

      Abstract: Soybean [Glycine max (L.) Merrill] yield and seed fatty acids, protein, and oil content are important traits for which an improved understanding of significant genomic regions would be useful. To accomplish this, a soybean population consisting of 203 F5 derived recombinant inbred lines (RILs) was developed and genotyped with 11,633 polymorphic single nucleotide polymorphisms (SNPs). Each RIL was grown in a single plot at Knoxville, TN in 2010; followed by replicated, multi-location field trials in 2013 and 2014. The data from 2010, 2013, and 2014 were analyzed together in order to detect quantitative trait loci (QTL) for these traits, and 30 total QTLs were detected. Five QTLs are candidates for confirmed status and one QTL is a candidate for positional confirmation. Many of the genes with mutations in close proximity to the fatty acid QTLs are involved in biological processes for fatty acids and/or lipids and could be considered possible candidate genes. Similarly, genes with mutations in genomic regions near yield, protein, and oil QTLs were plentiful and may contribute to the variation observed in these traits. Except for yield and stearic acid, each trait displayed pleiotropic effects with other traits in this study. Notable are the pleiotropic effects for oleic and linolenic acid on chromosomes 9, 13, and 19. Overall, the findings from this research contribute new information to the genetic understanding of soybean yield and seed fatty acids, protein and oil content. This understanding will be useful in making trait improvements.

      Abstract: Although many studies have been conducted on gene action of grain yield and yield related traits in maize, none of them focused on highland maize in Uganda. This study was conducted to establish the gene action controlling inheritance of yield and its related traits in highland maize hybrids. Thirty-six F1 hybrids generated from a 9 x 9 half diallel mating design, were planted with two local checks in three highland locations; Kalengyere, Kachwekano, and Buginyanya with two replications using a 2 x 19 alpha (0, 1) lattice design. Results showed that inheritance of ear length and anthesis-silking interval was controlled by both additive and non-additive gene action while the inheritance of days to anthesis, days to silking was mainly controlled by additive gene action. The inheritance of grain yield and other yield related traits was greatly influenced by environment and genotype x environment interaction. Considering the great influence of the environment and genotype x environment interaction on most of the traits including grain yield, further testing in additional locations over more seasons and broadening the genetic base of the parents is encouraged.

  • Competency assessment of directed amplified minisatellite DNA and start
           codon targeted markers for genetic diversity study in accessions of Vigna

      Abstract: Assessment of genetic diversity of Bambara groundnut (Vigna subterranea (L.) Verdcourt) accessions from Nigeria using informative molecular markers has become imperative for their genetic improvement and conservation. Comparative analysis of 30 V. subterranea from different locations in Nigeria was investigated using Directed Amplified Minisatellite DNA (DAMD) and Start codon targeted (SCoT) markers. The DNA was extracted using CTAB method for amplification. Both markers resolved the accessions into eight major groups using dendrograms and six clusters by principal component analysis. Alleles of 25 and 53 were obtained with DAMD and SCoT, respectively. Mean alleles, gene diversity, and polymorphic information content detected with DAMD were 10.2000, 0.6950, and 0.6600, while SCoT yielded 16.200, 0.847, and 0.836, respectively. Polymorphic loci were 130 and 142 in DAMD and SCoT, respectively. Both markers produced high polymorphism of 60.00-80% and 40.33-96.67% in DAMD and SCoT, respectively. Effective alleles (Ne) in both markers (DAMD: 1.1828-1.5927; SCoT: 1.1830-1.6779) were high. The Nei’s value (H) ranged from 0.1959-0.3238 in DAMD and 0.1533-0.3782 in SCoT. The Shannon’s information index (I) obtained from DAMD and SCoT were 0.3281-0.4635 and 0.1420-0.5557, respectively. Total gene diversity (Ht), diversity within population (Hs), coefficient of gene differentiation (Gst), and estimate of gene flow (Nm) from DAMD were 0.3304, 0.2673, 0.1907, and 2.1215, while SCoT had 0.3927, 0.3163, 0.1945, and 2.0713, respectively. Our study demonstrated that SCoT markers are more competent than DAMD and should be integrated in the exploration of genetic diversity and selection of unique accessions for improvement and utilization of V. subterranea.

  • Polyamines, affected the nitrogen partitioning, protein accumulation and
           amino acid composition of mung bean under water stress
    • Authors: Salar Farhangi-Abriz; Reza Faegi-Analou; Neda Nikpour-Rashidabad
      Pages: 279 - 285
      Abstract: Field experiments were conducted in two growing seasons as a split plot based on a randomized complete block design with four replications. Irrigation intervals (irrigation after 70 and 170 mm evaporation from class A pan) were assigned to main plots and spraying of polyamines (putrescine 0.1 mM, spermidine 0.1 mM, and spermine 0.1 mM) were allocated to the subplots. T nitrogen and sulfur content of different parts of mung bean, nitrogen uptake, protein filling duration, protein percentage of grain, maximum protein content per grains, grain and protein yields per unit area, methionine and serine contents reduced under water limitation, but grain filling rate, isoleucine, leucine, threonine, aspartic acid, glutamic acid, glycine, proline, tyrosine and arginine contents in grains raised. Treatment of plants with polyamines improved the contents of nitrogen and sulfur, nitrogen uptake, protein-filling duration, protein percentage, grain and protein yield per unit area, and histidine, methionine, phenylalanine, threonine, aspartic acid, glutamic acid, tyrosine, and arginine contents in grain. Putrescine had the highest grain and protein yields. Our results clearly indicated that polyamines with improving histidine, methionine, phenylalanine, and threonine content in mung bean grains improved the quality of mung bean protein.

  • Allelic variation at the gliadin coding loci of improved Ethiopian durum
           wheat varieties
    • Authors: Daniel Hailegiorgis; Chong Ae Lee; Song Joong Yun
      Pages: 287 - 293
      Abstract: The objective of this study was to determine gliadin allele compositions of 20 improved Ethiopian durum wheat varieties using acid-polyacrylamide gel electrophoresis (A-PAGE). Each block of co-dominantly inherited polypeptides encoded by gliadin loci were identified and their genetic diversities were estimated using statistical analyses. A total of 30 electrophoretic blocks were identified at five major gliadin loci. In addition, four novel gliadin blocks were identified. Gli-B1 and Gli-A2 loci had higher numbers of gliadin alleles (nine and ten, respectively) compared to other loci. Alleles Gli-A1c on chromosome 1A, Gli-B1c on chromosome 1B, Gli-A2a, and Gli-A2o on chromosome 6A, and Gli-B2h on chromosome 6B had maximal frequencies in their corresponding loci. Varieties were classified into three main clusters and one singleton based on genetic distances of detected gliadin alleles. These results indicate that Ethiopian durum wheat varieties are genetically diverse with unique allele compositions at gliadin-coding loci.

      Pages: 295 - 303
      Abstract: The wild species are considered as primary and secondary genepools for the world’s most important food crops. Here, we sequenced the complete chloroplast (cp) genome sequence of an American wild licorice, Glycyrrhiza lepidota for the first time to investigate their phylogenetic relationship among inverted-repeat-lacking clade (IRLC) legumes. The total length of the chloroplast genome is 127,939 bp, with 34.2% overall GC content. The chloroplast genome harbors 110 known genes, including 76 protein-coding genes, four ribosomal RNA genes, and 30 tRNA genes. Similar to other closely related plastomes, rpl22 and rps16 are absent. A total of 464 cp microsatellites (cpSSRs) were analyzed in the G. lepidota. The majority of the SSRs in this cp genome are penta-nucleotides (61.6%). Locally collinear blocks (LCBs) identified between the Glycyrrhiza glabra and G. lepidota cp genomes were showed that they were well conserved with respect to gene organization and order. Moreover, the phylogenetic analysis indicates that G. lepidota is closely related to its confamilial counterparts than to the other taxa of the IRLC legumes.

  • Nonparametric phenotypic stability analysis in advanced barley ( Hordeum
           vulgare L.) genotypes
    • Authors: Moslem Abdipour; Behrouz Vaezi; Mehdi Younessi-Hamzekhanlu; Seyyed Hamid Reza Ramazani
      Pages: 305 - 314
      Abstract: The development of genotypes with adaptation to a wide range of environments is one of the most important goals of plant breeding programs. In order to compare nonparametric stability measures and to identify promising high-yield and stable barley (Hordeum vulgare L.), 20 barley genotypes selected from the Iran/ICARDA joint project and grown in nine environments during 2009-11 in Iran. Four nonparametric statistical tests of significance for genotype × environment (GE) interaction and 10 nonparametric measures of stability were used to identify stable genotypes in nine environments. Results of nonparametric tests of G×E interaction (Kubinger, Hildebrand, and Kroon/ Laan) and a combined ANOVA across environments, indicated the presence of both crossover and non-crossover interactions. Also, only TOP and rank-sum values were positively associated with high yield. Thus, in the simultaneous selection for high yield and stability, only the rank-sum and TOP methods were useful in terms of the principal component analysis results, and correlation analysis of nonparametric stability statistics and yield. According to these stability parameters (TOP and rank-sum), three genotypes (G13, G12, and G17) were the most stable for grain yield. The results also revealed that based on nonparametric test results, stability could be classified into three groups, according to agronomic and biological concepts of stability.

  • Development, evaluation and genetic analysis of sulfosulfuron herbicide
           resistance in sorghum
    • Authors: David K. Ndung’u; John Derera; Pangirayi Tongoona; Joel Ransom
      Pages: 315 - 325
      Abstract: Herbicide tolerant varieties in combination with herbicide seed treatments can be used to manage Striga. However, there are no herbicide resistant sorghum varieties in Kenya. The objectives of this study, therefore, were to develop sulfosulfuron resistance in sorghum, to determine the level of resistance in resultant herbicide tolerant mutants, and to determine the genetic inheritance of herbicide tolerance in sorghum. Five ethyl methane sulphonate (EMS)-derived sulfosulfuron tolerant mutants (designated hb6, hb8, hb12, hb56, and hb462) were identified and selfed to M4 generation. Varying rates of sulfosulfuron, either as a spray or seed coat, were applied to determine the level of tolerance of the mutant lines. Mutant lines were also crossed with the wild-type Seredo and among themselves to determine mode of inheritance. Results showed that the susceptible wild-type Seredo was killed at the lowest herbicide rates of 0.5 g ha-1 and 1 g ha-1 sulfosulfuron. Dry matter from the spraying and seed coating experiments showed mutants to be up to 170 times more resistant to sulfosulfuron than the wild-type. The LD50 values indicated a general trend of hb46 > hb12 > hb462 ~ hb56 > hb8 for level of tolerance under both spraying and seed coating experiments. The F2 progeny of mutant X wild-type crosses segregated in a 1:2:1 fashion for resistant, intermediate, and susceptible, indicating semi-dominant inheritance. Intercrosses between mutant lines did not segregate for resistance in the F2 generation indicating the same mutation could be responsible for the tolerance in all five mutants.

  • Accuracy evaluation of the crop-weather yield predictive models of Italian
           ryegrass and forage rye using cross-validation
    • Authors: Jing-Lun Peng; Moon-Ju Kim; Mu-Hwan Jo; Doo-Hong Min; Kyung-Dae Kim; Bae-Hun Lee; Byong-Wan Kim; Kyung-Il Sung
      Pages: 327 - 334
      Abstract: The objective of this study was to evaluate the accuracy of the yield predictive models of Italian ryegrass (IRG, Lolium multiflorum Lam.) and forage rye (FR, Secale cereale L.) reported in previous studies through K-fold cross-validation method. In previous studies, statistical models were constructed for dry matter yield prediction of IRG and FR using general linear model based on climatic data by locations in the Republic of Korea. The yield predictive model for IRG cultivated in the southern region of the Korean Peninsula and Jeju Island were DMY = 78.178AGD–254.622MTJ + 64.156SGD–76.954PAT150 + 4.711SAP + 1028.295 + Location and DMY =–8.044AAT + 18.640SDS–7.542SAT + 9.610SAP + 17282.191, respectively. The yield predictive model for FR was as follows: DMY = 20.999AGD + 163.705LTJ + 113.716SGD + 64.379PAT100–4964.728 + Location. However, accuracy evaluation was not performed in the previous research. In this study, the reported models and the data set used for model construction were investigated. Subsequently, K-fold cross-validation was performed to assess the accuracy of the models. The results showed that the yield predictive models fit to the data sets well, while the accuracy of these models was in the common level since the data sources might keep major variances in cultivars, climatic conditions, and cultivated locations. Therefore, models with better fitness and accuracy might be constructed based on a data set with smaller variance. Hence, the standardization of the crop cultivation experiments is very necessary to decrease the variance in the historical data used for future crop yield modeling.

  • Evaluation of carbon sources, gelling agents, growth hormones and
           additives for efficient callus induction and plant regeneration in Indian
           wheat ( Triticum aestivum L.) genotypes using mature embryos
    • Authors: Kapil Malik; Deepshikha Birla; Honey Yadav; Manish Sainger; Darshna Chaudhary; Pawan K. Jaiwal
      Pages: 185 - 192
      Abstract: Various factors affecting in vitro regeneration like different carbon sources, different gelling agents, and growth additives were assessed comprehensively for callus induction and plant regeneration for five Indian wheat cultivars using mature embryos as the explants for the first time. The tissue culture responses of cultivars WH-1105, HD-2967, and PBW-343 have not been reported earlier. Besides, the effect of different concentrations of the cytokinin, zeatin has also been optimized. Using the optimized factors, the efficiency of five different varieties, i.e., HD 2967, C 306, RAJ 3765, WH 1105, and PBW 343 was evaluated for regeneration. Modified MS basal medium containing dicamba reduced precocious germination of the embryo and induced embryogenic callus more efficiently. Removal of embryogenic calli from non-regenerable structures during early callus phase improved plant regeneration. These calli on zeatin (1.0 mgl-1) and dicamba (0.1 mgl-1) containing medium showed the highest regeneration frequency (98%) with a maximum of 8-9 shoots per calli. Maltose had the maximum callusing and regeneration percentage than other carbon sources. Various gelling agents did not have any significant difference on the regeneration. Of all the varieties, C-306 and HD-2967 were found to be more regenerative and can be used in transformation experiments.
