Evaluation and selection of different varieties and lines of soybean for breeding for valuable traits in the Central European part of Russia

Soybeans is the most important source of high quality protein using as food and oil. Soybean protein is balanced for amino acid composition that is advantage in comparison with other legumes, oil crops, and cereals. Soybean protein contains all the essential amino acids in a ratio close to the animal protein. Due to the acute deficiency of protein, the interest in soybean production and breeding of new varieties are constantly growing worldwide. The early ripening lines for the duration of the vegetation period and interphase periods of development were selected. The soybean samples with a maximum seed weight per a plant, thousand-seed weight and the largest number of seeds in a bean were revealed. The genotypes with the optimal displays of these traits for the breeding in the different directions were identified.
