Effect of interaction of parental components on the content of protein and amino acids in triticale grain

The research defined the effect of parent components of rye, ‘Donar’ cultivar, and wheat cultivars, ‘Aurora’ and ‘Liwilla’, on the content of total protein and protein amino acid composition of grain of primary forms of octoploid triticale (♀Aurora x ♂Donar, ♀Liwilla x ♂Donar). There was also determined the effect of crossing of the octoploid triticale forms obtained with hexaploid triticale CZR142/79 on the chemical characteristics (qualitative). The results obtained showed that primary forms of octoploid triticale contained more protein in grain than the parent plants. It can give a potential in further breeding work of giving high-protein high-starch cultivars. Both forms of octoploid triticale showed a higher level of lysine. Also the marked amino acids show that the biological value protein of triticale ‘Liwilla’ x ‘Donar’ was more similar to wheat protein, which points to a considerable effect of components derived from the basic form on the nutritional value.
