Abstract. The studies were conducted in 2015–2019 in the Sverdlovsk region. The purpose was to determine the adaptive abilities of pea varieties to select the most adapted to the conditions of the region. The material of the study were five pea varieties included in the State Register of Breeding Achievements, the promising variety of Fakel, and 13-03 and 14-279 lines. The five varieties were Krasnoufimsky 93 (1997), Marafon (2004), Krasnous (2010), Krasnoufimsky 11 (2014, the standard), and Edem. Fakel variety has been undergoing State variety test since 2019. The lines are planned to be transferred to the State variety test in 2020 and 2021. Weather conditions during the years of the experiment ranged from favourable (in 2018 and 2019 Ij was 0.68 and 13.72, respectively) to unfavourable (in 2015 and 2016 Ij was -4.54 and -0.95, respectively) and extreme (in 2017 Ij was -8.91). We identified three groups of varieties with different levels of adaptability to abiotic factors. Edem variety (bi = 1.19) belongs to the intensive group. Plastic varieties are Krasnous (bi = 0.95), Fakel (bi = 0.99), Marafon (bi = 1.02), Krasnoufimsky 11 (bi = 1.03); variety samples 13-03 (bi = 1.03) and 14-279 (bi = 0.95) are also of the plastic type. Krasnoufimsky 93 variety (bi = 0.88) are of the extensive type. The high breeding genotypic value was characteristic of Marafon variety (11.35) and 13-03 (10.69) and 14-279 (10.68) lines. These genotypes were also characterized by high genetic flexibility (23.10, 24.70, and 23.25, respectively), the highest adaptability (2.31, 1.85, and 1.03, respectively), and high relative stability (42.87, 44.79, and 42.72, respectively).
Keywords: pea (Pisum sativum L.); variety; variety sample; productivity; adaptability; stability; plasticity.
