The results of the study of 250 collection samples of spring soft wheat of various ecological and geographical groups are presented in order to identify the source material that combines optimal plant height and high productivity for the conditions of the forest-steppe zone of the Middle Volga region. The work was carried out in 2017–2020 in the Samara region. The study and evaluation of samples was carried out according to the Methodology of the state variety testing and the methodological recommendations of the VIR. The average height of plants in the samples over the years of research varied within 68.5-109.2 cm, the coefficient of variation of the trait was 11.86-13.72 %. The presence of a positive average and weak correlation between the yield and plant height, regardless of the moisture conditions of the year (r = 0.15-0.47), was revealed. A strong positive relationship was observed between the height of the samples and the following weather factors: precipitation in June (r = 0.94), precipitation during the growing season (r = 0.87), hydrothermal coefficient of June (r = 0.93), hydrothermal coefficient for the growing season (r = 0.83). The highest grain yield was formed by samples from the group of undersized and medium-grown, on average 416 and 428 g/m2, respectively. A number of highly productive varieties were identified: 3 medium-grown samples (105 cm) with a yield of 419.7-435.7 g/m2 and 21 undersized samples (85-102 cm) with an average grain yield of 485.0-585.7 g/m2. Dwarf specimens sample a stable manifestation of short-stemmed growth over the years and high resistance to lodging were noted. According to the research results, it was found that the optimal height of plants for the forest-steppe zone of the Middle Volga region is in the range of 85-105 cm. The selected undersized and medium-grown samples with high grain yield and dwarf samples with high resistance to lodging are recommended for use in breeding programs of the region and places with similar conditions.

Цель исследований — оценка перспективных сортообразцов клевера ползучего по продуктивности и адаптивности в условиях лесостепи Среднего Поволжья. Исследования проводили на опытном поле Обособленного подразделения в г. Пензе ФГБНУ «Федеральный научный центр лубяных культур» в 2016–2019 годах. Объектом исследования были перспективные сортообразцы клевера ползучего в питомнике конкурсного сортоиспытания, заложенном в 2015 году. Агроклиматические условия в годы исследований различались. Оптимальные условия для роста и развития клевера складывались в 2016 (ГТК за период отрастания – созревания семян составил 1,1) и в 2017 годах (ГТК = 1,2); 2018 и 2019 годы были засушливыми, ГТК в эти годы составлял 0,5 и 0,4 соответственно. В среднем за 2016–2019 годы урожайность сухого вещества клевера ползучего колебалась в пределах 2,43–2,76 т/га, лучшим по урожайности оказался сортообразец Пл-90-5 (2,76 т/га). Изменчивость урожайности у всех сортов высокая. Почти все сортообразцы показали высокую экологическую адаптивность и пластичность: значение bi у них варьировалось в пределах 0,95–1,15. Наиболее адаптивными и пластичными сортообразцами были Пл-90-2, Пл-90-3, Пл-90-4 и Пл-90-5 (bi=0,95–1,10, σd2=0,0–0,07). Наиболее высоким показателем уровня стабильности сорта отличился сортообразец Пл-90-5 (116,7%), ещё у двух сортообразцов он составил 110,2–115,5%. Наиболее высокий индекс стабильности для данной культуры (0,06) отмечен у четырёх сортообразцов, в том числе у стандарта. Из изучаемых сортообразцов четыре показали коэффициент адаптивности 1,0–1,07, наибольший показатель — у Пл-90-5. Образцы Пл-90-2 и Пл-90-3 обладали наибольшей стрессоустойчивостью. Наибольшая генетическая гибкость между генотипом и факторами среды была отмечена у сортообразцов Пл-90-4 и Пл-90-5 (2,74–2,77). The aim of this research was to evaluate promising genotypes of white clover with regard to its productivity and resistance in the forest-steppe of the Middle Volga region. The experiment took place on the trial field of the Penza branch of the Federal Research Center of Fibre Crops in 2016–2019. A competitive variety trial started in 2015. Environmental conditions varied among years of study. Optimal conditions were in 2016 and 2017, hydrothermal coefficient amounted to 1.1 and 1.2, respectively. Weather of 2018 and 2019 was dry, hydrothermal coefficient reached 0.5 and 0.4, respectively. Dry matter (DM) productivity varied within 2.43–2.76 t ha-1. Pl-90-5 line performed the best producing 2.76 t DM ha-1. Yield variation was high among all the genotypes. Plants showed high adaptability and plasticity: bi varied within 0.95–1.15. Such lines as Pl-90-2, Pl-90-3, Pl-90-4 and Pl-90-5 had the best adaptability and plasticity (bi=0.95–1.10, σd2=0.0–0.07). Pl-90-5 had the highest stability of 116.7%. The highest stability index of 0.06 was determined for four genotypes, including standard variety. Four genotypes had adaptability coefficient of 1.0–1.07, Pl-90-5 showed the highest adaptability. Pl-90-2 and Pl-90-3 had the highest stress-resistance. The highest plasticity between genotype and environment was observed for Pl-90-4 and Pl-90-5 (2.74–2.77).
