Soybean, an essential crop with diverse industrial uses, benefits from selecting climateadapted varieties to enhance yields and product quality.The purpose of study was to compare the yield of soybean varieties of different origins to identify the most productive and quality varieties.To fulfil purpose, a field experiment was conducted in 2022, where 130 soybean varieties and lines were investigated.As a result of the study, it was found that the number of beans per plant was 4-38 pieces, the maximum value was found in the following varieties: Suiyang 1, SC Farta, Jinyaan 55, Kenfeng 20, Dongnong 63, Chera 1-1, Progress, lines No. 33, No. 92, No. 77.High yields were found in varieties Ivushka, Suiyang 1, SC Farta, Beidou 43, Beidou 19, Kenfeng 20, Huajiong 2, Kenfeng 6, Chera 1-1, Beidou 47, Progress, lines: No. 78, No. 33, No. 83, No. 16. 78, No. 33, No. 83, No. 16.The protein content of soya seeds ranged from 38.66% to 47.25%.Varieties with high seed protein content: Beidou 26, Kendou 60, Alaska, Osmon, K-0126, K-0128.Quality indicators weakly correlate negatively with soybean yield, influenced by factors like some productive nodes, seed weight per bean, thousand-kernel weight, and other characteristics.
