The expansion of the distribution area of soybeans in the northern and southern directions of the Republic of Kazakhstan revealed the need to create soybean varieties that are resistant to drought stress and changes in daily temperatures, which lead to cracking of beans and shedding of seeds. The identification of soybean cultivars for the presence of a white eye on the scar was carried out, which indicates a dense accretion of the seedling with the bean valves. Extensive germplasm of soybeans of the Department of Leguminous Crops of LLP «Kazakh Research Institute of Agriculture and Plant Growing» with a volume of 1790 varieties was phenotyped. Germplasm includes collection varieties of the world collection, as well as linear and constant genetic material of our own selection. Identified 391 varieties with this trait. The largest non-dropping number from the world collection belongs to varieties of Russian and Ukrainian selection. Of the varieties of domestic selection, only two have this trait - Almaty and Zara. It was found that in hybrid populations F3 with participation as the maternal form of the Zara variety, from 20 to 100% of the lines have this trait.
