THE EFFECT OF STRESSFUL WEATHER CONDITIONS AT DIFFERENT STAGES OF VEGETATION ON THE FORMATION OF PRODUCTIVITY ELEMENTS IN VARIETIES OF WHITE LUPIN (LUPINUS ALBUS L.) OF THE SELECTION OF RUSSIAN STATE AGRARIAN UNIVERSITY -MOSCOW TIMIRYAZEV AGRICULTURAL ACADEMY

The article determined and presented the productivity components of different varieties of white lupine (Lupinus albus L.) in the field experiments of2019-2020 in the conditions of the northern part of the Central Chernozem region. The varieties Degas, Delta, Start, Manovitsky, adapted to the region ’s conditions were studied, as well as the varieties Timiryazevskiy and Ghana recently included in the State Register of Breeding Achievements. Despite the high potential of the varieties, there is a significant decrease in yield and its instability during cultivation in different years and different soil and climatic conditions. During the years of research, weather conditions had a substantial effect on the rate ofplant development, the duration of individual periods of crop formation, and, in general, the time of the growing season from sowing to the complete ripening phase. The studies determined the effect of stress factors associated with changes in meteorological conditions of the growing season on the variability of plant seed productivity parameters. The varieties of white lupine with a determinant growth type created at Russian State Agrarian University -Moscow Timiryazev Agricultural Academy were characterized by a high level of adaptive potential to moisture deficiency (drought) and heat stress. The biological yield of the varieties was high; on average, for the varieties, it was 530 g/m² in 2019 and 570 g/m² in 2020. The seed yield was formed by 85 and 90% over the years due to the seeds of the main shoot. The coefficient of variation (V%) averaged 12% and 10% for varieties; on lateral shoots, it was three times higher.
