DIFFERENCES IN AMINO ACID COMPOSITION OF KERNELS IN SOFT WHEAT.
The article examines the amino acid composition of the grain in ten soft wheat accessions of diverse origin, and assesses their
nutritional and biological value. In the study, the grain composition of ten cultivar samples derived from the soft wheat germplasm
of Central Asia and Kyrgyzstan was analysed, and the amounts of 20 amino acids were determined in mg per gram. The results
showed that significant genetic differences in amino acid composition exist among the soft wheat varieties studied. Two of these
varieties stood out for their high concentration of essential amino acids, while one variety demonstrated tolerance to stress
conditions through its high proline content. The results obtained confirm the importance of considering the amino acid composition
of wheat varieties when selecting them.
