Variability of the trait ‘1000-seed weight’ of the promising pea lines

The purpose of the current research was to study and identify new promising pea lines with stable indicators trait ‘1000-seed weight’. carried out in fields laboratory for legumes breeding seed production FSBSI Agricultural Research Center “Donskoy”, located southern part Rostov region, Competitive Variety Testing 2018–2020. objects were 12 developed by “ARC “Donskoy”. standard variety ‘Aksaisky usaty 5’. conducted 2018–2020 resulted assignment all samples medium-size group, which had 150–250 g ‘B-3626/20’ (213.3 g) ‘B-3733/9-1’ (210.7 produced largest size seeds. Intervarietal variability differed through years. In 2018 it 13.6%, 2019 11.5% 2020 21.1%, an annual average indicator 19.8%. analysis intravarietal showed that lowest (less than 10%) characteristic Usaty 5’ (5.9%), ‘G-1014’ (7.7%) (9.1%). (10-20%) ‘G-1008’ (13.7%), ‘B-3790/30-3’ (11.2%), (19.8%). rest samples, high (more 20%) years study. this study, highest homeostasis 157.5. Not a single line has exceeded figure. This indicates least among studied changed seeds under different growing conditions Among lines, (86.3), (64.6) homeostaticity due
