Adaptability and stability of conventional soybean by GGE biplot analysis

ABSTRACT The conventional soybean production has been re-establishing itself every year, due to the fact that international market demanded products with high agronomic performance and nutritional quality, free of genetically modified organisms. This study aimed evaluate adaptability genotypes in southwestern Goiás state (Rio Verde, Montividiu Santa Helena de Goiás), Brazil, during 2017/2018 2018/2019 crop seasons. A randomized blocks design was used, being tested eight (the cultivars BRS284, BRS283, BRS232, BRS317, NT11-1277, INT3459 M6101 line NT1478SP). grain oil yields, as well protein contents, were evaluated. Multi-environment analyses performed using a heterogeneous residual variance model, GGE biplot analysis used describe interrelationships between environments. most adapted stable BRS 317 for yield 283 yield. They also corresponded more closely ideotype specific region, thus proving be promising. NT1478SP showed highest content. In season, discriminating production, regarding yields.
