The article presents experimental data on complexes of economically valuable traits of early potato variety Bashkirski. A positive reaction was found for early planting (up to 2.0 t / ha or 6.1%), germination of seed tubers (4.1 t / ha or 12.2%) and negative - for thickening of plantings (unprofitable). Early planting of germinated tubers provided a yield increase of 5.9 t / ha or 18.1%, conditional income - 72.8 thousand rub. / ha.

High temperature (heat) stress reduces tuber yield and quality of potatoes. Screening potatoes for heat tolerance is increasingly important, considering the climate change scenario and expansion of potatoes to countries where heat stress is an issue. In vitro screening for tolerance to abiotic stresses offers several advantages, including quick evaluation of numerous genotypes (clones) in reduced space, controlled environmental conditions (temperature and photoperiod), and free from confounding variables inherent to greenhouse and field conditions. In this study, we explored the feasibility of using a temporary immersion bioreactor system for heat tolerance screening of potatoes. We determined the best hormone-free microtuberizing media for this system (MSG with 8% sucrose) to enhance microtuber number and size. Comparisons of microtubers produced at 30°C as heat treatment, with 16°C as normal condition, allowed to identify heat tolerant and susceptible potato clones. The use of bioreactors allowed distinguishing well-formed (non-deformed) from deformed microtubers. Heat stress increased the total biomass of plant tissues in all the clones. However, the effect of heat stress on microtuber number and weight varied among the clones. Incubation at 30°C decreased the weight and number of non-deformed microtubers in all the clones except for Reveille Russet in which the weight of non-deformed microtubers was significantly increased and the count of non-deformed microtubers was not affected. The potato variety Reveille Russet, which was selected under high-temperature field conditions in Texas, had many non-deformed microtubers per explant and the highest microtuber weight among four clones evaluated under heat stress. We described a faster and reliable in vitro microtuberization system for abiotic stress tolerance screening, identified Reveille Russet as a promising heat-tolerant potato variety, and confirmed Russet Burbank and Atlantic as susceptible heat-tolerant checks.

Эксперименты проводили в 2018-2020 годах на новом раннем сорте картофеля Гулливер селекции ФГБНУ «ФИЦ картофеля имени А.Г. Лорха». В опыте изучали срок, густоту посадки и приемы внесения минеральных удобрений. Клубни высаживали в два срока: ранний (третьяя декада апреля при температуре почвы не ниже 5 °С) и базовый (контроль) – через 7-10 дней после первого срока. Посадку проводили на фоне удобрений, внесенных локально в три приема при нарезке гребней и последующих междурядных обработках двумя лентами: основное N90P90K135(контроль); дробное (стартовое N60P60K90 + подкормка N30P30K45 через 7-10 дней после всходов); стартовое N30P30K45 + подкормка N30P30K45через 7-10 дней после всходов + подкормка N30P30K45в фазу бутонизации. Густота посадки: 44; 50 и 56 тыс. клубней/га по схеме 75×30; 75×27 и 75×24 см. Ранняя посадка ускоряла появление всходов на 5-6, а фазы бутонизации и цветения растений на 3-7 дней. Увеличивались масса ботвы, площадь ассимиляционной поверхности листьев на 2,0 т/га и 3,6 тыс. м2/га. Период вегетации растений и накопления урожая клубней удлинялся на 8-10 дней в сравнении с контролем. Прибавка урожая от ранней посадки достигала в среднем за 3 года до 1,7 т/га или 4,0%, а от дробного внесения удобрений до 2,1 т/га или 5,0% в сравнении с соответствующими контролями. Совокупное применение агроприемов в опыте позволило получить прибавку урожая в размере 3,6 т/га или 8,5%. Условный доход составил 46 тыс. р/га, а себестоимость – 3,4 р/кг, что на 0,2 р/кг меньше, чем в контроле. Показатели качества при этом были практически одинаковыми. Загущение посадок до 50 и 56 тыс. клубней/га способствовало увеличению урожайности клубней в среднем на 2,9-3,1 т/га или до 7,3%, в сравнении с контролем. Условный доход возрастал на этих вариантах в среднем до 9 тыс. р/га. Experiments were carried out in 2018-2020 on a new early potato variety Gulliver in Russian Potato Research Centre. In the experiment, we studied different agrotechnical techniques, including the time, density of planting and methods of applying mineral fertilizers. Tubers were planted in 2 terms: early (3rd decade of April at a soil temperature of not less than 5 °C) and basic (control) - 7-10 days after the first term. Planting was carried out on background of fertilizers applied locally in three ways while preparing of ridges and subsequent inter-row treatments with two strings: the main N90P90K135(control); fractional (starting N60P60K90 + top dressing N30P30K45 7-10 days after germination); starting N30P30K45 + top dressing N30P30K45 7-10 days after germination + top dressing N30P30K45 in the budding phase. Planting density: 44; 50 and 56 thousand tubers/ha according to the scheme 75×30; 75×27 and 75×24 cm. Early planting accelerated the emergence of seedlings by 5-6, and the phases of budding and flowering of plants by 3-7 days. The weight of the tops, the area of leaves assimilation surface increased by 2.0 t/ha and 3.6 thousand m2/ha. The period of plants vegetation and tubers accumulation was extended by 8-10 days in comparison with control. The yield increase from early planting reached an average of 1.7 t/ha or 4.0% in 3 years, and from fractional appliance of fertilizers to 2.1 t/ha or 5.0% in comparison with corresponding controls. The combined use of agricultural methods in experiment allowed to obtain a yield increase of 3.6 t/ha or 8.5%. Conditional income amounted to 46 thousand rubles / ha, and the cost price – 3.4 rubles/kg, which is 0.2 rubles/kg less than in the control. The quality indicators were almost the same. Thickening of plantings to 50 and 56 thousand tubers/ha contributed to an increase of yield by an average of 2.9-3.1 t/ha or up to 7.3%, compared with the control. Conditional income increased on these options on average to 9 thousand rubles/ha.
