  • Major In Vitro Techniques for Potato Virus Elimination and Post
           Eradication Detection Methods. A Review
    • Abstract: Abstract Potato is an economically important agro-industrial crop that is conventionally propagated, however; its potential transmission of viruses through seed tubers from generation to generation is a major limitation of potato yield production. In order to produce potato virus-free and sufficient amount of potato seed tubers, several approaches of in vitro methods for virus elimination have been developed. Meristem culture has been used alone or combined with techniques such as thermotherapy, electrotherapy, cryotherapy and chemotherapy as the best alternative method for treating potato infected by viruses. Recent literature has shown that to eliminate potato virus significantly depends upon the potato cultivar, antiviral agents, type of virus, the duration of heat treatment. Appropriate duration for efficiency elimination is still under investigation. Viral elimination rate can be detected through serological methods such as enzyme-linked immunosorbent assay (ELISA) and molecular biology technique such as real time reverse transcriptase polymerase chain reaction (real time RT-PCR) that are used for pre and post elimination virus detection to evaluate the efficiency and the accuracy of virus elimination method. The purpose of this review is to highlight virus elimination methods in potato and recommending the most effective tool for virus detection in order to ensure the production of potato plantlet free of viruses.

  • Germplasm with Resistance to Potato virus Y Derived from Solanum chacoense
           : Clones M19 (39–7) and M20 (XD3)
    • Abstract: Abstract Potato virus Y (PVY) causes one of the most serious and widespread diseases in North America. In recent years, the virus has become increasingly difficult to control. Durable dominant genes for resistance to PVY exist in potato germplasm and provide an effective control strategy. This paper describes a Solanum chacoense clone (M19) that is homozygous for a PVY resistance gene. The gene is linked to a previously published marker for Rychc found in Solanum chacoense. M19 was crossed with a diploid S. tuberosum clone to produce an adapted clone carrying the resistance gene. This hybrid clone is named M20. M20 tuberizes in the field, producing round tubers with white skin and flesh and moderate size. M20 is resistant to PVYO, PVYN:O, and PVYNTN. Both M19 and M20 are female and male fertile, so they are being released as sources of PVY resistance for breeding programs.

  • Image Analysis for Measuring Disease Symptom to Bacterial Soft Rot in
    • Abstract: Abstract Bacterial soft rot is a devastating disease in potato. However, it is difficult to evaluate disease resistance because there are a number of ways the bacterium can infect tubers, including through lenticels, in bruised tissue, and through wounds. Thus, various screening methods have been developed to evaluate resistance in potato tubers. The methods published to date are limited in their ability to measure symptoms quickly and accurately in a large number of samples. Therefore, we developed a new high throughput phenotyping method to evaluate soft rot disease symptoms the assistance of image analysis software. This method has proven to be very efficient in evaluating disease symptoms.

  • Potato as a Source of Nutrition for Physical Performance
    • Abstract: Abstract Health professionals universally agree on the importance of a balanced diet, and the fallacy of relying on any one or two food groups, as the means of achieving peak physical performance and health. A review of the existing sports nutrition literature indicates that different types of athletes and physically active people may have slightly different nutritional requirements, but the main tenets of sports nutrition have not changed much over the last 25 years. The specific combinations may vary, but carbohydrates, protein, and fluids are vital components of an active individual’s diet. Further, most available research supports the notion that optimal physical performance requires carbohydrate - and, specifically, high-quality, nutrient-dense carbohydrate from whole food sources, like potatoes. High- quality carbohydrate sources – foods that offer an array of macro- and micronutrients as well as energy, can help to build a strong nutritional foundation for the level of training, recovery, and adaptation that most physically active people seek to achieve. Low carbohydrate diets will not generally allow athletes to train at the intensity required to attain peak physical performance.

  • Potato virus Y in Seed Potatoes Sold at Garden Stores in Western
           Washington: Prevalence and Strain Composition
    • Abstract: Abstract Between 2016 and 2018, a study was conducted to evaluate the prevalence and significance of Potato virus Y (PVY) present in seed potatoes distributed through garden stores in western Washington. Seed potatoes, particularly those exhibiting symptoms of cracking possibly caused by PVY, were purchased and grown-out in greenhouse tests. A relatively high incidence (47% in 2016; 26% in 2017; 29% in 2018) of the collections (15, 31, and 49 seed lots in total, respectively) produced plants that were confirmed by ELISA to be infected with PVY. Seed sold for organic production yielded approximately ten times more PVY infections than seed sold for conventional production. Strain typing revealed infections primarily by PVYO, PVYNTN, and PVYN-Wi. Mixed infections of PVYO/NTN and PVYO/N-Wi were detected a few times and no new or unusual PVY strains were found. These PVY strain types often were recovered from plants originating from cracked seed tubers, and the incidence of PVYN-Wi from cracked tubers increased (22% to 69%) during the study. PVYN-Wi remains an important constituent of the region’s PVY strain composition since its first detection in 2011. Garden enthusiasts and organic potato growers need more information about PVY to help mitigate the risk that PVY infected seed tubers could pose to commercial potato production fields.

  • Captures of Bactericera cockerelli (Šulc) (Hemiptera: Triozidae) Adults
           Affected by the Presence of Volunteer Potatoes ( Solanum tuberosum L. )
    • Abstract: Abstract The potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), is a key potato (Solanum tuberosum L.) pest that has the ability to vector the plant pathogenic bacterium Candidatus Liberibacter solanacearum (Lso), the putative causal agent of zebra chip disease of potato. The insect primarily feeds and completes its life cycle on Solanaceous crops and weeds; however, in the Columbia Basin of Oregon and Washington, B. cockerelli has been found in association with crops such as maize (Zea mays L.) and wheat (Triticum spp), both belonging to the Poaceae family. We hypothesize that this is due to the presence of volunteer potato; in this region, the potato crop is in a 3-yr rotation with either maize or wheat. Consequently, we evaluated potato, maize, wheat, maize + volunteer potato, wheat + volunteer potato on captures of B. cockerelli adults in a 2-year field experiment using an inverted leaf blower and yellow sticky cards. Data collected in this study confirms that B. cockerelli has an affinity for potato, although, B. cockerelli could be found in maize and wheat mainly when volunteer potatoes were present. In addition, B. cockerelli counts varied depending if using inverted leaf blower or yellow sticky cards. Knowing that B. cockerelli is found in fields where volunteer potatoes are present, it should be taken into consideration for large-scale potato psyllid management.

  • The Weed Link in Zebra Chip Epidemiology: Suitability of Non-crop
           Solanaceae and Convolvulaceae to Potato Psyllid and “ Candidatus
           Liberibacter Solanacearum”
    • Abstract: Abstract Potato psyllid (Bactericera cockerelli) is a vector of “Candidatus Liberibacter solanacearum”, the pathogen associated with potato zebra chip disease. While the psyllid apparently colonizes potato from non-crop Solanaceae or Convolvulaceae, the identity of these weed sources is uncertain. We examined susceptibility of ten non-crop species (one Convolvulaceae and nine Solanaceae) to potato psyllid and Liberibacter, with an emphasis on psyllid populations (northwestern and western haplotypes) and plant species that are present in the Pacific Northwest. Psyllids of the western haplotype survived and developed on all plant species, while psyllids of the northwestern haplotype survived on all species except Solanum physalipholium. All species except Lycium barbarum and Convolvulus arvensis were susceptible to Liberibacter. Results of our study provide the most extensive examination of plant suitability to potato psyllid and Liberibacter and will lead to improved capabilities of predicting which potato fields are at risk to arrival of infective psyllids.

  • Potato Vitamins, Minerals and Phytonutrients from a Plant Biology
    • Abstract: Abstract As the link between diet and health becomes increasingly characterized, the nutritional value of foods is being increasingly prioritized by the public. This can create both challenges and opportunities for plant breeding programs and food processing companies. This review will focus on the nutritional composition of potatoes and examine the role potatoes can play in providing global food security. The amounts of vitamins, minerals and phytonutrients in potatoes vary tremendously depending on the cultivar and are also influenced by environment. Potatoes are well known to be good sources of potassium and vitamin C. They also contain an array of other bioactives, including high amounts of phenylpropanoids, compounds known to have diverse health-promoting roles in humans. While potatoes already contain generous amounts of various phytonutrients, by taking advantage of the available extensive germplasm resources, future cultivars can be further improved and provide additional options that help satisfy rapidly evolving consumer preferences and changing market demands.

  • Effect of Diverse Compost Products on Potato Yield and Nutrient
    • Abstract: Abstract Compost application to agricultural fields can increase soil organic matter content and soil productivity. This study compared diverse compost products with a non-amended control in small plot and on-farm trials for effects on tuber yield and plant nutrient availability under rain-fed potato production in New Brunswick, Canada. In the small plot trial, mature compost products resulted in a small increase in plant N availability, whereas immature products resulted in net N immobilization. Composts high in K increased plant K availability. However, these effects on nutrient availability did not result in a significant effect on tuber yield. In on-farm trials, compost did not significantly increase yield averaged across 19 site-years of trials. This suggests that any short-term nutrient benefit from application of these wood waste and manure based composts is unlikely to influence crop yield, although there may be the potential to reduce nutrient application rates, particularly for K.

  • Comparison of Methods to Distinguish Diploid and Tetraploid Potato in
           Applied Diploid Breeding
    • Abstract: Abstract Diploid (2n = 2x = 24) and tetraploid (2n = 4x = 48) germplasm are commonly used in potato breeding programs. Potato breeders need to efficiently and inexpensively differentiate between diploid and tetraploid progeny in dihaploid induction crosses as well as 2x-2x crosses where 2n gametes may occur in the parents. In this study, we compared the chloroplast count, genome-wide SNP genotyping and flow cytometry methods to determine ploidy. Twenty-eight clones were used as reference samples (14 diploid lines (2n = 2x = 24), 14 tetraploid (2n = 4x = 48) varieties and advanced breeding lines) to compare the three ploidy determination methods. The chloroplast count method was used to determine the ploidy level in the 28 reference samples, and 102 potato breeding lines derived from diploid (2x-2x) crosses. The Infinium 12 K V2 Potato Single Nucleotide Polymorphism (SNP) Array was used to examine the 28 reference samples and the 102 breeding lines. The results obtained from both chloroplasts counts and SNP genotyping techniques determined that there was a total of 84 diploid lines and 18 tetraploid lines. Flow cytometry was also used to determine ploidy level in a subset of 42 lines (28 reference lines set and 14 breeding lines). All three methods of ploidy determination (chloroplast counting, SNP genotyping and flow cytometry) agreed for all samples evaluated. These results demonstrate the usefulness of chloroplast counting as an efficient and inexpensive method for breeders to differentiate ploidy between diploid and tetraploid potato in applied breeding programs.

  • Possibility of Recommending Potassium Application Rates Based on a Rapid
           Detection of the Potato Petiole K Status with a Portable K ion Meter
    • Abstract: Because of the variations in the K amount required to produce 1 t potatoes and the poor relationship between soil potassium content and potato yield, recommended K-fertilizer rates based on soil tests are unreliable for potato production. This research was set to test the possibility of establishing a potato plant K diagnosis method with a portable K ion meter. The results confirmed the luxury absorption of K by potato. Moreover, the potato petiole K content by a portable K ion meter was linearly related to the vine and tuber K contents as well as the plant accumulated K level. Therefore the petiole K concentration is a good indicator of plant K status. Furthermore, the relationship between the relative potato yield and the petiole K content fits a quadratic equation, thus the threshold petiole K content could be calculated based on the minimum petiole K content at the highest relative yield. Resumen Debido a las variaciones en la cantidad de K requerida para producir 1 t de papas, y la pobre relación entre el contenido de potasio en el suelo y el rendimiento de papa, los niveles de fertilizantes de K recomendados con base a las pruebas del suelo, no son confiables para la producción de papa. Esta investigación se estableció para probar la posibilidad de establecer un método de diagnóstico de K en la planta de papa con un iónmetro de K portátil. Los resultados confirmaron la absorción de lujo de K por la papa. Aún más, el contenido de K en el pecíolo de la papa por el iónmetro de K portátil estuvo relacionado linealmente a los contenidos de K del follaje y del tubérculo, así como al nivel de K acumulado en la planta. De aquí que la concentración de K en el pecíolo es un buen indicador de la situación del K en la planta. Más aún, la relación entre el rendimiento relativo de la papa y el contenido de K en el pecíolo se ajusta a una ecuación cuadrática, entonces el umbral del contenido de K en el pecíolo pudiera calcularse con base en el contenido mínimo de K en el pecíolo en el rendimiento relativo más alto.

  • Intumescence Injury in the Leaves of Russet Burbank Potato Plants is
           Mitigated by Calcium Nutrition
    • Abstract: Abstract Many plants including potato, tobacco, tomato, and geraniums often develop intumescence (oedema) injury, which is observed exclusively on plants grown in controlled environments. Early studies have suggested a link between light quality and intumescence by showing UV and/or far-red light mitigation of injury. Here, we report that intumescence can be mitigated by calcium nutrition. Commercial cultivars of Solanum tuberosum L. cvs ‘Russet Burbank’ and ‘Atlantic’ were grown from in vitro shoot cultures in 20.4 L pots within a climate-controlled greenhouse. Plants were irrigated daily to excess with Peter’s Professional Peat Lite Special 20–10-20 fertilizer (0.52 g·L−1 tap water) supplemented with either 1 mM or 10 mM CaCl2·2H2O. We evaluated 13 replications from both potato cultivars and Ca2+ treatments. Intumescences were observed at about 32 days after calcium treatments began, exclusively on the upper and lower leaf surfaces of Russet Burbank. Upper canopy leaves of Russet Burbank showed approximately 65 and 5% intumescence injury for the 1 mM and 10 mM Ca2+ treatments, respectively. Average leaf calcium concentration was nearly double in the plants supplemented with 10 mM compared with 1 mM Ca2+. Tuber yield and foliage weight were higher in the plants supplemented with 10 mM Ca2+ as compared with 1 mM Ca2+ and suggests that intumescence injury reduced growth and partitioning. These data provide evidence that supplemental calcium can mitigate intumescence injury on susceptible cultivars of potato in controlled environments.

  • Three Cycles of Recurrent Maternal Half-Sib Selection Continue to Reduce
           Foliar Late Blight in a Diploid Hybrid Solanum phureja-S. stenotomum
    • Abstract: Abstract Increasing levels of foliar resistance to late blight, caused by Phytophthora infestans, have previously been reported through two cycles of recurrent maternal half-sib selection in a diploid hybrid population of Solanum phureja-S. stenotomum. The objective of this study was to determine if continued improvements for resistance to late blight could be realized by another cycle of selection. Four clones from each of 72 maternal half-sib families constituting the cycle four population were evaluated for late blight resistance in replicated field trials in Pennsylvania in 2015 and 2016. The experimental design was a randomized complete block design with two replications each year. P. infestans US23 genotype was used in inoculations each year. Area under the disease progress curve (AUDPC) was calculated based on visual assessment of foliar disease five times late in the season each year and subjected to statistical and genetic analyses. Mean AUDPC in the cycle one, two, three, and four populations was 652, 556, 276, and 173, respectively. Narrow-sense heritability for resistance decreased in the cycle four population (h2 = 0.54) as compared to prior populations (0.77 ≤ h2 ≤ 0.80), however, broad-sense heritability remained high (H = 0.83). Additional improvements for late blight resistance are likely to occur if this approach is continued.

  • DNA Fingerprinting and Genetic Diversity Analysis with Simple Sequence
           Repeat Markers of 217 Potato Cultivars ( Solanum tuberosum L.) in China
    • Abstract: Abstract Since 1950, more than 620 potato cultivars have been released from Chinese breeding programs, some of which have similar genetic background and phenotype. In this study, 16 parental cultivars widely used in breeding were used to screen 138 simple sequence repeat (SSR) markers. Out of 138 SSR markers, 20 were polymorphic that were used to analyze the genetic diversity of 217 potato cultivars grown in China. In total, 249 alleles were detected with these 20 markers and 244 of them (97.99%) showed polymorphism. The number of alleles ranged from 7 to 22 with an average of 12.45 alleles per primer and polymorphic information content (PIC) ranged from 0.64–0.93 with an average of 0.83. Fragment sizes varied from 80 to 380 bp. Based on PIC values and the clarity of PCR amplification bands, 11 SSR markers were selected and able to differentiate all of the 217 cultivars. The estimated similarity using these polymorphic SSR markers between the cultivars ranged from 0.63 to 0.99, indicating a narrow genetic base. Fingerprinting and genetic diversity analysis in this study provides useful information for the protection of intellectual property, as well as the exploration and utilization of these potato cultivars.

  • Differences in Zebra Chip Severity between ‘ Candidatus Liberibacter
           Solanacearum’ Haplotypes in Texas
    • Abstract: Abstract ‘Candidatus Liberibacter solanacearum’ (Lso) is a phloem-restricted plant pathogen that is vectored between host plants by the potato psyllid, Bactericera cockerelli. Lso infects solanaceous crops whithin North America and New Zealand and is responsible for causing zebra chip (ZC) in potato. Two Lso haplotypes (A and B) have been identified infecting potato (Solanum tuberosum). Previously, we identified differences in disease severity associated with each Lso haplotype in tomato (Solanum lycopersicum). In this study, the severity of ZC symptoms was evaluated for Lso haplotypes A and B independently or in co-infection in Atlantic variety potato tubers grown in Texas fields. Discolorations in tuber vascular tissues were measured in potato chips using a published 6-point visual scale and compared among plants submitted to five treatments: no psyllids (control), psyllids not infected with Lso (LsoFree), psyllids infected with Lso haplotype A (LsoA), psyllids infected with Lso haplotype B (LsoB), and psyllids infected with both haplotypes (LsoAB). These experiments were performed a total of three times, twice in the Lower Rio Grande Valley (Weslaco, TX) during the winters 2014 and 2018 and once during the spring 2015 in the Texas Panhandle (Springlake, TX). This study showed that significantly lower ZC symptom severity was associated with plants treated with LsoA-infected psyllids compared to plants treated with either LsoB- or LsoAB-infected psyllids; however, this difference was marginal. This difference might be relevant for the disease biology; it has no impact on the tuber suitability for the market. This study also showed that average tuber mass was significantly lower in plants infected with Lso compared with uninfected plants and that this reduction in mass was similar among Lso haplotype treatments. Overall, this study demonstrates that Lso haplotypes A and B cause slightly different ZC symptom severity and that ZC symptom severity in plants treated with psyllids co-infected with both haplotypes is similar to the symptoms associated with Lso haplotype B.

  • General and Specific Combinatorial Aptitude in a F1 Population of Solanum
           phureja with Resistance to Phytophthora infestans
    • Abstract: Abstract Solanum phureja is one of the most important crops for farmer economy in Colombia, and Phytophthora infestans is considered its main limiting disease. This pathogen is managed using chemical products, generating high production costs as well as environmental pollution. The use of resistant varieties is a strategy that is currently well positioned for the control of this disease, leaving the task of identifying superior parentals to plant breeders. Moreover, the analysis of general and specific combinatorial aptitudes of potential parental genotypes gains importance. The aim of this study was to establish the general and specific combinatorial aptitudes of five elite parental cultivars. For this, 979 clones were assessed. General combinatorial aptitude results show statistically significant differences for the Paola, Primavera and Ocarina parentals. On the other hand, the specific combinatorial analysis allowed concluding that the combinations Ocarina×Violeta and Primavera×Galeras contain non-additive effects involved in inheritance.

  • Antifungal Activity of a Fatty Ammonium Chloride Amylose Inclusion Complex
           against Fusarium sambucinum ; Control of Dry Rot on Multiple Potato
    • Abstract: Abstract The cationic amylose-hexadecylammonium chloride inclusion complex (Hex-Am) was found to be an effective antifungal treatment for Fusarium sambucinum (Fückel), a causal agent of potato dry rot. The Hex-Am treatment was effective against F. sambucinum in vitro and in situ, with an effective 50% inhibitory concentration of 400 μg/ml; active component concentration of 20 μg/ml. The amylose complex alone, and blended with polyvinyl alcohol (PVOH), was effective in controlling dry rot in five varieties of potatoes with up to a 99% reduction in damage to the potato tubers. The amylose complex showed no apparent signs of phytotoxicity, with wound periderm reforming within one week of storage at 15 °C and 90% RH. The Hex-Am treatments form an effective antimicrobial film at the wound site, significantly inhibiting fungal damage to the wounded tubers.

  • Effect of Potato Flour on the Rheological Properties of Dough and the
           Volatile Aroma Components of Bread
    • Abstract: Abstract The effect of potato flour as partial replacement of wheat flour at levels of 6%, 15% and 30% on dough rheological properties and flavor properties of baked bread were investigated. Results showed that the substitution ratio at low level of 6% in bread baking is perfectly feasible, the potato bread is softer than the all-wheat bread. Potato flour substitution at higher level will result in a serious decreasing of processing performance, due to the protein weakening increasing, the dough formation time and stability time decreasing. Furfural and acetone can be used as marker components to identify the potato bread from the all-wheat bread, based on their exclusive presence in bread contains potato flour. Furfural is a nonenzymatic browning reaction product in potato flour, while acetone may come from the potato flour made with some defective potatoes (soft-rot-infected). The relative content of hydroxyacetone in the crust is high, and the hexyl alcohol is low, the result is opposite in the crumb. In conclusion, potato flour at low substitution rate such as 6% is feasible.
