Abstract
Long-term studies on leached chernozem soils were carried out at the experimental base of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy (Michurinskiy district, Tambov region) under the conditions of the northern part of the Central Black Earth Region. In the breeding program to create varieties of white lupine (Lupinus albus L.) with a determinant growth type studies were conducted to assess the degree of effect of stress factors associated with the weather conditions on the dynamic parameters and seed productivity of white lupine varieties selected by the RSAU-MTAA (Start, Gamma, Delta, Dega, Deter 1). In the research under the conditions of 2021–2022 the new varieties of white lupine Timiryazevsky and Gana showed a high level of adaptive potential to moisture deficiency (drought) and heat stress: the average yield for two years of studies was 540 g/m2 (variety Timiryazevsky) and 516 g/m2 (variety Gana).
