Results of a study of soybean source material for breeding purposes under the conditions of Primorsky Territory

Background . A study of the soybean gene pool adapted to conditions Primorsky Territory in search useful agronomic traits is essential for further use breeding programs. Materials and methods Soybean accessions from germplasm collection were tested 2019–2021 at Federal Scientific Center Agricultural Biotechnology Far East named after A.K. Chaika. The included 213 various origin. Cv. ‘Primorskaya 4’ served as reference. An objective assessment potential said research material was made. Results Three years experiments resulted selecting promising genotypes with a set important Compared reference 4’, an increase more than 35% productivity observed cultivars ‘Mestnaya’ (Russia), ‘Jilin’ (China), ‘Montreal’ (France), ‘XP 977-1.9’ (USA). Cvs. ‘No. 075-2’ (USA), ‘K0152’ (Ukraine), ‘Muzanze Stamm M 4789/74’, ‘SOJA 1065’ ‘Adsoi’ (Germany) characterized by earliness (100 days). ‘HS Atlas’ may be interesting breeders due their highest oil content: 25.9% 26.0%, respectively. protein content found cvs. ‘Zhuravushka’ (39.2%), ‘XN (41.9%), ‘Torlitsa’ (41.9%) (39.5%). ‘Pi 6D 4182’, ‘Skelya’ manifested resistance Septoria brown spot. results adaptability showed that following different origin had environmental stresses: (–2.5), (–2.0) ‘Kassidi’ (–3.0).
