Biochemical evaluation of grain quality parameters of soybean varieties from the world collection of VIR in the conditions of the Lower Volga region

In 2019-2020, biochemical evaluation of grain quality indicators of soybean varieties from the VIR collection by main groups of nutrients under the conditions of the Lower Volga region was conducted. The differences and peculiarities of the gross energy value of grain were revealed according to the results of the research. The samples with high content of protein and fat in the grain were selected for further use in various directions of selection work on this crop. The coefficient of variation of biochemical grain parameters in soybean varieties varied between 2.7-8.7 %, which indicates its low variability.
