We studied responsiveness of the different soybean cultivars bred at the Federal Scientific Center of Legumes and Cereal Crops on application of the bio-fertilizers “Bio-Terra” Growth Energy and Gumistim. These preparations had positive effects on germination energy and laboratory germination of seeds and on development of root system and accumulation of dry matter in soybean plants of the cultivars Lantsetnaya and Shatilovskaya 17.

The purpose of the research was to determine the inheritance of black seed coat colour in lentil variety ‘Beluga’. The seeds collected from F1 plants in cross of ‘Rauza’ (yellow seeds) × ‘Beluga’ (black seeds) were of grey colour with black mottles. F2 ratio of nonblack and black seeds was 62:6, which corresponded to 15:1 dihybrid segregation. It is concluded that the black seed coat colour of ‘Beluga’ is controlled by two dominant genes.
