| Abstract | The aim of the study was a comparative analysis of winter bread wheat samples developed with the participation of spelt wheat in Uman national university in terms of the biological value of protein. All created samples significantly exceeded the standard in terms of grain content in each year of the study. This indicator varied over the years from 14.8–15.4% in 2021 to 15.4–16.2% in 2023. Highest grain protein content (on average 16.1%) was observed in sample 6750. The study established that the amino acid content in the grain of the developed winter bread wheat samples varied depending on the genotype within the range of 180.11–206.21 mg/g. Highest sum of essential amino acids in the grain of winter bread wheat samples was recorded in samples 6750 (38.67 mg/g) and 3872 (34.63 mg/g). Among the essential amino acids, leucine predominated, its content varying depending on the genotype within 8.31–9.88 mg/g, as well as valine – 5.32–6.19 mg/g. The content of non-essential amino acids ranged from 72.98 mg/g in sample 6274 to 206.21 mg/g in sample 6750. By the sum of non-essential amino acids, winter bread wheat samples 3872, 4075, and 6750 significantly exceeded the control variant. Among the non-essential amino acids, glutamic acid predominated (29.01–31.79 mg/g). The limiting amino acids in the grain of the developed winter bread wheat samples were lysine and tryptophan, whose amino acid score ranged within 60–80%. In addition to lysine and tryptophan, the studied genotypes had a slight deficiency of threonine, while samples 4075 and 6274 also showed a deficiency of isoleucine. The amino acid score of other essential amino acids was non-limiting. The coefficient of metabolic efficiency did not change significantly, ranging from 0.43 in sample 3872 to 0.47 in sample 6274. The highest integrated score was recorded in winter bread wheat samples 3872 and 6750, which best met the human biological demand for glutamic acid (201–23-4%), isoleucine (198–247%), valine (215–248%), and leucine (182–215%). | ||
