The article presents the results of a comparative assessment of grain productivity and adaptability indicators of various varieties of yellow lupine cultivated on soddy-podzolic sandy soil. We studied 8 varieties of lupine of domestic selection of the All-Russian Research Institute of Lupine, Novozybkovskaya SHOS; neighboring countries - Belarus and foreign selection (Germany), as well as the hybrid material of the Novozybkovskaya SHOS for 2016–2020. The adaptability of variety samples was comprehensively tested in terms of environmental stability and plasticity, using the criterion of "yield". Changes in meteorological conditions over the years of research made it possible to objectively assess the variation in the productivity of lupine by grain. For five years of testing, the grain yield varied from 6.4 c/ha Vladko (Belarus) to 11.8 c/ha, Novozybkovsky 100 (Novozybkovskaya SHOS). On average, changes in the productivity of varieties of VNII lupine from 9.7 to 11.3 c/ha, Novozybkovskaya SHOS – 10.7–11.8 c/ha, Belarusian breeding – 6.4–9.1 c/ha, foreign – 8.3–8.7 q/ha. Samples 5-10-84 (13.2 c/ha), 1-08-7-75 and 2-13-33 (12.7 c/ha) and 7-13-65 (12,5 q/ha). According to the set of indicators of adaptability, the All-Russian Research Institute of Lupine Nadezhny and Bulat turned out to be the best among the varieties; Belarusian selection Kastrychnik; Novozybkovskoy SHOS – Druzhny 165 and Novozybkovsky 100. From the hybrid material of the Novozybkovskaya SHOS promising numbers 1-08-7-75, 5-10-84, 4-12-302, 2-13-33, which have genetic flexibility, adaptability and stability in conditions of sandy and sandy loamy soils of the South-West of the Bryansk region.
