Study of biochemical composition of seeds and green beans of vegetable cowpea (Vigna Ung. ssp. Sesquipedalis)

The article presents the results of investigation of the variability of biochemical parameters of seeds and green beans of vegetable cowpea accessions (Vigna unguiculata ssp. sesquipedalis (L.) Verdc.) introduced for use in breeding. Variations of biochemical parameters of seed quality and green beans (such as protein, fat, ash content, fiber, NFES) were established. New data on the fractional composition of proteins (albumins, globulins, prolamins, glutelins) from seeds and green beans were obtained. These data are of great importance for the evaluation of the starting material and the formation of a breeding program and the selection of rational strategies of individual selection from the source populations.
