  • Application of growth substances through tree injection in banana for
           increasing yield and fruiting characters

    • Authors: JOLLYBEN JAYESHKUMAR PATEL
      Abstract: The present investigation was carried out on banana cv. Grand Naine, trated with nine chemical treatments viz., control (T1 ), GA3 @ 10 ppm (T2 ), GA3 @ 20 ppm (T3 ), GA3 @ 30 ppm (T4 ), BA @ 2.5 ppm (T5 ), BA @ 5.0 ppm (T6 ), NOVEL+ @ 0.5 % (T7 ), NOVEL+ @ 1.0 % (T8 ), NOVEL+ @ 1.5 % (T9 ), applied through injection at the time of bell emergence. The results revealed that the injection of GA3 @ 30 ppm (T4 ) tended to show the maximum bunch weight (36.38 kg), fruit yield (126.31t/ha), bunch length (101.78 cm), bunch girth (119.17 cm), finger length (22.96 cm), finger girth (13.99 cm) and finger weight (205.78 g), took minimum days from flowering to harvest (89.28). However, the maximum number of fingers per bunch (179.89) and number of hands per bunch (14.06) were observed under the injection of NOVEL+ @ 1.5 % (T9 ) followed by GA3 @ 30 ppm (T4 ).

  • Efficient microspore embryogenesis for the development of doubled haploid
           plants in broccoli

    • Authors: Rohit kumar sharma, Pradeep Kumar Choudhary, Arun Agarwal
      Abstract: The most acceptable strategic tool for creating homozygous inbred lines is the development of doubled haploids (DH’s) by microspore culture technique. The current research focuses on development of DH’s by microspore culture through the optimization of important factor limiting its efficiency. The effect of carbon sources, temperature shock for embryogenic response and effect of different plant growth regulators (PGRs) on effective regeneration was studied in four commercial varieties/hybrids of broccoli viz., Palam Vichitra, Lucky, Palam Samridhi and Palam Kanchan. Interaction between variety and carbon source (V × C) revealed maximum numbers of embryos per plate (330.00) in genotype V3 (Palam Samridhi) when supplemented with 13% sucrose (C2 ). While interaction between varieties and temperature (V × T) revealed V3 × T3 with significantly highest embryo yield (93.11). Interaction between temperature and carbon sources (T × C) revealed the maximum number of embryos per plate with treatment combination T3 × C2 (382.67). Overall, the highest embryogenic response (715.00) was obtained in Palam Samridhi (V3 ) genotype when supplemented with 13% sucrose (C2 ) at temperature treatment T3 (4°C-48 hr + 32°C-24 hr + 25°C-Cont). Further, maximum regeneration of embryos (75.00%) was recorded in genotype V3 when supplemented with 1.0 mg/l BAP (H5). Ploidy analysis of 952 microspore-derived plants from four broccoli genotypes revealed 52.31% plants were haploids, 43.17% plants were doubled haploids, 1.05% of plants were triploids, 2.84% were tetraploids and 1.20% were mixoploid. The present findings will accelerate doubled haploid based hybrid breeding in broccoli.

  • Influence of mulching on fruit development and quality attributes of
           strawberry

    • Authors: NAV PREM SINGH
      Abstract: Effect of different type of mulches on fruit development of ‘Winter Dawn’ strawberries was investigated. The plants were mulched with silver-black, black and red plastic mulches and paddy straw. The observations on physical and biochemical attributes were documented at six fruit developmental stages viz., small green (7 DAFS) (S1), large green (14 DAFS) (S2), white (21 DAFS) (S3), initial red (28 DAFS) (S4), partial red (31 DAFS) (S5) and full red (34 DAFS) (S6). Fruit physical parameters increased exponentially, and showed slow growth rate during later stages of fruit development. Fruits harvested from plants mulched with red mulch were of bigger size with significantly higher fresh weight and juice per cent as compared to other treatments. Significantly higher biochemical attributes and attainment of earlier maturity was recorded from the plants mulched with inorganic materials than straw mulch. Changes in fruit pericarp L*, a* and b* values attributed to the development of attractive red colour on 31 DAFS in silver-black and red mulch treatments. Fruit firmness and juice acid content followed a decreasing trend with the advancement of maturity. Nutrient contents of fruit showed significant variations during fruit development, and did not exhibit definite trend for P, Fe and Mn contents. The order of abundance of nutrients in fruits was K>N>Ca>P>Mg>Mn>Fe>Zn>Cu under different mulching treatments.

  • Physico-chemical, nutritional and microbiological profiling of probiotic
           Aloe vera juice

    • Authors: Priya Katyal Batra
      Abstract: Aloe vera juice is rich in vitamins, minerals, fibers, nutrients, anthraquinones, saponins, phytosterols and salicylic acid. Its composition proves it to be an excellent source of prebiotics and a potential substrate for probiotics. Though Aloe Vera juice has been used for its medicinal and health benefits since ages, its value addition by converting it into a synbiotic is lesser exploited so far. This investigation involves physicochemical, microbiological, antioxidant and sensory evaluation of probiotic Aloe vera juice developed at the lab scale by using Lactobacillus acidophilus MTCC 10307. The probiotic culture was inoculated into the Aloe vera juice with initial concentration of 109 -1010 CFU/ml. The probiotic viability, pH, total soluble solids (TSS), titrable acidity, total sugars, reducing sugars, non-reducing sugars, lactic acid content, anti-oxidant activity, vitamin C and microbial contaminations were measured at weekly interval upto six weeks. The probiotic viability remained above 8 log CFU/ml during the first four weeks of storage at 4°C. The total plate count, coliform count and yeast and mould count also remained within satisfactory limits. The sensory evaluation of aloe vera juice with and without probiotic inoculation revealed it to be potential synbiotic product.

  • Reduction of browning in minimally processed fresh-cut lettuce

    • Authors: pawan singh gurjar, Shyam Raj Singh, Anil Kumar Verma, Shailendra Rajan
      Abstract: The investigation was carried out to assess the effect of post-harvest dip treatment of melatonin (10, 100 and 1000 µmol L-1) on shelf life and sensory qualities of minimally processed fresh cut lettuce, kept at 6±2ºC for 8 days. Melatonin treatment was found effective in maintaining freshness and sensory qualities of lettuce during storage. Browning was reduced by 45% with 44.10% higher visual quality index in 100 µmol L-1 melatonin treated samples than control on the 6th day of storage. Maximum total chlorophyll, phenol and antioxidants, with least activity of browning related enzyme i.e. peroxidase (POD) was also observed in 100 µmol L-1 melatonin treated samples during the course of storage period. No significant variation was observed between melatonin @ 10 µmol L-1 treated and control samples. Browning index value had significant negative correlation with total chlorophyll, phenol and antioxidants whereas POD activity had significant positive correlation. It can be inferred from the present investigation that post harvest treatment of 100 µmol L-1 melatonin maintained the quality of minimally processed lettuce for 6 days storage at 6±2ºC temperature.

  • Estimation of evapotranspiration under polyhouse and open field conditions
           in capsicum

    • Authors: ARUNADEVI K
      Abstract: Field experiment was conducted at Agricultural Engineering College and Research Institute, Kumulur, Tamil Nadu, to estimate crop evapotranspiration and crop coefficient of capsicum under polyhouse and open field conditions for the two consecutive seasons during 2019. Microclimatic parameters like maximum and minimum temperature (ºC), relative humidity (%) and light intensity (lux) were recorded during the study. EM 50 soil moisture sensors were used to observe the soil moisture status for the entire crop growth period. The actual crop evapotranspiration was worked out by using standard soil water balance equation. The crop coefficient for capsicum was estimated for different crop growth stages. During winter season, crop coefficient for initial, developmental, middle and end stages were 0.49, 0.76, 0.98 and 0.88, respectively, for the crop grown inside polyhouse and same were 0.59, 0.77, 1.02, 0.90, respectively, for the crop grown outside condition. The water use efficiency of capsicum under drip irrigation was calculated as 56 Kg/ha.mm during summer season and 66.7 kg/ha.mm during winter season similarly, the water use efficiency of 11.7 kg/ha.mm and 17.6 kg/ha.mm during summer and winter season, respectively in open field condition.

  • Performance evaluation and scope of onion improvement under hot arid
           conditions

    • Authors: Ajay Kumar Verma
      Abstract: The present investigation was carried out at the experimental farm of ICAR-CIAH, Bikaner Rajasthan during rabi season of 2019 and 2020. A wide range of variability was reported for the characters such as plant height at 60 DAS, leaves per plant, polar diameter, bulb weight, scales per bulb and bulb yield. Bhima Red, Bhima Kiran and Bhima Shakti were identified as the high yielding varieties for cultivation under hot arid conditions during rabi season. Highest genotypic coefficient of variation was observed for bulb yield. Higher heritability estimates conjugated with high genetic advance as per cent of mean were recorded for plant height at 60 DAS, leaves per plant, bulb weight and bulb yield. Correlation coefficient analysis revealed that polar diameter, equatorial diameter, bulb weight and TSS had the significant positive correlation with bulb yield. Path analysis revealed true association between yield and bulb weight as correlation was due to direct effect. Hence, selection based on these characters would be effective in further improvement of onion under hot arid conditions.

  • Heterosis and combining ability for fruit quality, mineral nutrients and
           post harvest traits of muskmelon

    • Authors: Harshawardhan Choudhary, Koushik Saha, Ram Asrey, Vinod K Sharma
      Abstract: Twenty-one F1 hybrids of muskmelon, along with seven parents from two horticultural groups, were evaluated for heterosis and combining ability for fruit quality, mineral nutrients, and post harvest traits, in a half diallel scheme, during the spring-summer and kharif seasons. For all fruit quality, mineral nutrient, and post harvest traits, sca component of variance (σ2 s) was greater than the gca component of variance (σ2 g), indicating the importance of non-additive gene action for improvement. Kashi Madhu (P6 ) was the best general combiner for K, Zn, Cu, Ca and Mg content, whereas Pusa Madhuras (P5 ) for ascorbic acid and Mn content. Besides, the parent DCM-31 (P4 ) was the best general combiner for TSS and Fe content; Hara Madhu (P7 ) for acidity and Na content; DHM-162 (P2 ) for respiration rate and ethylene emission rate. The hybrid, DCM-31 × Pusa Madhuras was found to be the best heterotic combination for ascorbic acid and Fe content. The cross DMM-159 × Pusa Madhuras was the best heterotic hybrid for TSS and Cu content. Similarly, the cross DHM-163 × DMM-159 was superior for respiration rate and ethylene emission rate. The cross-combinations, DCM-31 × Kashi Madhu, DHM-163 × DCM-31, DMM-159 × Hara Madhu, DCM-31 × Hara Madhu, DMM-159 × DCM-31 and DHM-163 × Pusa Madhuras, exhibited highest heterosis for acidity, Na, K, Zn, Mn and Ca content. None of the hybrids excelled in fruit quality, mineral nutrients, and post harvest traits, indicating the importance and need for multiple crossing breeding approaches to improve muskmelon fruit quality, mineral concentration, and post harvest life.

  • Anatomical studies of in vitro raised haploid and diploid citrus plants
           generated through gamma irradiated pollen

    • Authors: Manoj Kundu, Anil Dubey
      Abstract: Histological studies of stem, root and leaf of ovule and embryo cultured haploid and diploid plantlets of Citrus grandis × C. sinensis and Citrus grandis × C. limetta crosses were carried out. Area of xylem and phloem in stem increased gradually with increasing age of explants in both cross combinations; however, it was measured minimum in haploid plantlets (1.95 and 1.62 mm2 , respectively) as compared to diploid ones. Similar trend was also observed for the area occupied by xylem and phloem in root section of those plantlets. A negative relation was obtained between the ploidy level and per cent area of xylem and phloem within the stem and root of those plantlets. No cuticular and epicuticular wax was observed on the leaf surface in any plantlets irrespective of ploidy level and age of cultured explants, although the leaf thickness increased gradually with the increasing age of the explants with minimum in haploid one. Although, the area of all the parameters evaluated in stem, root and leaf under this experiment were reduced in haploid plantlets but they were well developed and similar to diploid ones which confirmed that these haploid plantlets can also grow normally under open field condition, if intensive care is taken during acclimatization.

  • Variation of anthocyanin, phenolics, flavonoids and antioxidants in grape
           genotypes

    • Authors: Mahendra Kumar Verma
      Abstract: An experiment was conducted on 29 grape genotypes of diverse origin for various health promoting compounds for two seasons (2018 and 2019). The content of bioactive compound varied significantly for total monomeric anthocyanins (37.54 to 863.97 mg/kg in coloured genotypes), total phenolics (57.13 to 339.07 µg/ ml GAE), total flavonoids (68.80 to 209.87 mg QE/g fw), DDPH (2.72 to 11.54 µg TE/g fw), CUPRAC (3.82 to 43.73 µg TE/g fw) and FRAP (1.28 to 14.12 µg TE/g fw) activity. ‘Black Prince’ was found most promising in terms of higher amount of total phenolics, CUPRAC and FRAP antioxidant activities; ‘Pusa Navrang’ for total monomeric anthocyanins and ‘Punjab Purple’ and ‘Centennial Seedless’ ‘for total flavonoid and DPPH antioxidant activity. The information will be useful in future for development of phytochemical rich grape varieties.

  • Influence of weather variables on different phenophases of mulberry

    • Authors: Deepak Kumar Sarolia
      Abstract: An experiment was conducted to quantify the weather influence on different phenophases of mulberry in
      irrigated hot arid ecosystem of western Rajasthan during 2017- 2020. Mulberry plants remained in dormancy
      during January, and the break with catkin emergence was observed during late winter (26 February), when
      there was relatively high humidity. The fruiting took place during mid-March to April, but some time it got
      extended up to April end to May first week. The total span from catkin emergence to fruit harvesting observed
      44±10 days. Hot and high wind velocity (>19 km/h) damaged the crop drastically, and rains during fruiting
      (April) extended the harvesting duration. Accumulated heat unit of four years mean value was recorded as
      461.03 degree days. The highest degree days (170.5 to 254.1 degree days) was recorded between first flower
      initiation (FFI) to date of end of flowering (DEF), while it was lowest (74.5 to 140.7 degree days) between first
      fruit harvest (FFH) to peak time harvest (PTH). The heat use efficiency was observed less in aberrant years
      due to poor yield. Relationship of phenophase (fruiting) and weather events presented a negative correlation
      with wind velocity and maximum temperature, while it was positive with rainfall.

  • Vulnerability studies of okra genotypes to bhendi yellow vein mosaic virus
           (BYVMV)

    • Authors: ramesh kumar yadav
      Abstract: India is the leading okra producer globally, but its production suffers due to losses caused by Bhendi yellow vein mosaic virus (BYVMV) disease which is transmitted by whitefly. Due to its unstable resistance nature and limited availability of sources for resistance in cultivated types, the crop improvement programme of okra has not taken a fast pace. In this study, sixty-four distinct genotypes of okra were screened for their resistance to BYVMV under natural epiphytotic conditions of Delhi. It was found that the disease incidence (DI), coefficient of infection (CI), vulnerability index (VI), and adult whitefly count (AWC) varied significantly amongst the different okra genotypes. The highest mean DI was recorded in Pusa Sawani (86.5%) and DI was 0 % in the genotypes Pusa Bhindi-5 (DOV-66), DOV-89 and DOV-92. The coefficient of infection (CI) was highest in Pusa Sawani (70.39 %). Maximum VI was recorded in Pusa Sawani (83 %) and 0 % VI in the wild genotypes IC-141040, IC-90560 and cultivated Pusa Bhindi-5, DOV-81 and DOV-92. Similarly, AWC was maximum in Pusa Sawani (30.4) and the lowest number in DOV-26 (1.2). The number of whiteflies peaked at 80 days after sowing and subsequently decreased. Pusa Sawani was the most susceptible genotype and Pusa Bhindi-5 and DOV-92 were the most resistant genotypes based on this study. The resistant genotypes Pusa Bhindi-5 and DOV-92 can be used for the transfer of BYVMV resistance in other susceptible lines or varieties and also for hybrid development in future okra improvement programmes.

  • Screening of short-day onion cultivars of India for vitamin-C content

    • Authors: ANIL KHAR
      Abstract: Onion has been used to cure various health problems and has many functional and therapeutic values. Its bulbs are a rich source of sulphur containing organic compounds, minerals, vitamins, etc. However, onion bulbs as a source of vitamin C is specifically undervalued. Vitamin C or ascorbic acid is an indispensable constituent of all living cells and tissues for various metabolic functions and acts as a strong antioxidant to mitigate oxidative stress. For quantification of ascorbic acid, forty-five short-day Indian commercial varieties representing white to red bulb colour were used for the present study. A highly significant variation in the concentration of ascorbic acid among genotypes was observed. The ascorbic acid concentration in raw bulbs ranged from 4.94 to 45.05 mg/100 g on a fresh weight (FW) basis, whereas, it varied from 59.51 to 173.56 mg/100 g on a dry weight (DW) basis. Variations in ascorbic acid content were observed with respect to bulb colour. White onion exhibited lower concentration compared to red coloured varieties. As per the recommendation of ICMR, one hundred grams of raw onion bulb of variety containing the highest ascorbic acid could supply 85- 90% of the recommended daily allowance (RDA) of vitamin C to adults per day. This information would also be of great help for future breeding programs to develop new cultivars possessing higher amounts of ascorbic acid to ensure nutritional security in India.

  • Determination of pesticides residues and evaluation of decontamination
           treatments in chili

    • Authors: Anjana Srivastava
      Abstract: The present studies were conducted with an aim to develop multiresidue methods for the simultaneous determination of nine pesticides viz. acephate, acetamiprid, chlorpyrifos, cypermethrin, imidacloprid, thiamethoxam, profenofos (insecticides), carbendazim and tebuconazole (fungicides) in chili. The extraction of pesticides was done by solid phase and liquid-liquid extraction following modified QuEChERS method. Analysis of acephate and it’s metabolite methamidophos, acetamiprid, imidacloprid, thiamethoxam, carbendazim and tebuconazole was done by HPLC-UV and that of chlorpyrifos, cypermethrin and profenophos by GC-ECD after optimization. The chili samples were also subjected to nine different decontamination treatments namely washing with running tap water, soaking in lukewarm water (50-60°C), soaking in aqueous solutions of 1% NaCl, 5% NaHCO3 , 2% CH3 COOH, 0.01% KMnO4 and three commercial formulations (Veggi clean, Nimwash and Arka herbiwash) for ten minutes, to assess the level of pesticide decontamination. Results revealed that the validated methods like precision, linearity, accuracy, limit of detection and quantification for the simultaneous quantitative determination of the above pesticides were suitable. The pesticides residues obtained after different decontaminant treatments from chili fruits were assessed on their maximum residue (MRL) limits. Soaking in 2% CH3 COOH solution (60.98 to 86.27% removal) was found to be significantly superior to the rest of the treatments to decontaminate all the pesticides except profenofos, whereas treatment with 1% NaCl solution (54.7 to 80.05% removal) proved to be the next best treatment in removal of different pesticides.

  • Heterosis for seed and seedling traits in papaya

    • Authors: Preeti Singh, JAI PRAKASH, S K Singh, A K Goswami, zalir Hussain
      Abstract: The current study was aimed to explore the heterosis expressed in the seed and seedlings of 36 papaya hybrids originating from the 6 inbred lines. The results revealed the manifestation of heterosis, occurred in the seed and seedling stage of papaya. The cross combinations, P-9-5 × P-7-2, P-9-12 × PN and PN × P-9-5 exhibited positive average heterosis and heterobeltiosis for physical seed traits. The genotypes, P-9-5, P-9-12, P-9-5 × P-9-12 and P-9-12 × P-9-5 were observed with positive mid-parent heterosis and heterobeltiosis for the seedling traits. The hybrid, P-7-9 × PN and PS3 × P-7-9 showed positive average heterosis (5.89% and 9.91%) and heterobeltiosis (3.41% and 2.09%) for germination percentage, respectively. Whereas in case of seedling length and weight (fresh and dry), the hybrid combination, P-9-5 × P-9-12 exhibited the positive heterosis. The heterosis effect estimated helped us to identify the superior performing hybrids like, PN × P-7-2, PN × P-9-5, P-7-2 × PN, P-7-2 × P-7-9, P-7-9 × P-9-5, P-9-5 × P-7-2, P-9-5 × P-9-12, P-9-12 × PN, P-9-12 × P-7-2, P-9-12 × P-9- 5and PS3 × P-7-9, in the initial stage of seedling development.
