Формирование плодов , семян и урожайност ь сортов люпина белого (Lupinus albus L.) с детерминантным типом роста

Abstract

Long-term studies were carried out at the experimental base of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy (Michurinsky district, Tambov region) in the conditions of the northern part of the Central Chernozem region. The breeding program to create new varieties of white lupine (Lupinus albus L.) of determinant type was carried out on leached chernozems and included studies to assess the effect of stress factors on the main dynamic parameters and seed productivity of varieties of white lupine selected by the RSAU – MTAA. In the research in the conditions of 2021–2022 the new varieties of white lupine Timiryazevsky and Gana had a high level of adaptation potential in drought conditions: the yield was 540 g/m2 (Timiryazevsky) and 516 g/m2 (Gana).
