EFFECT OF INTROGRESSION OF AEGILOPS GENETIC MATERIAL IN THE GENOME OF TRITICALE HYBRID LINES ON THE BIOCHEMICAL COMPOSITION OF GRAIN
Abstract
The study of the influence of the genome composition of triticale lines with genetic material Aegilops diploid species on the biochemical composition of grain was made. The high content of protein and starch in the grain was detected in triticale lines, in which genomes aegilops foreign material is present either as an entire chromosome, or a translocation. The increase in the content of protein and essential amino acids is observed for the line carrying the 2R(2U) chromosome substitution. Thus, the triticale genome reorganization, which has occurred as a result of introgressive hybridization of hexaploid triticale and genome-substituted forms of wheat, contributes to the creation of new economically valuable forms with a high content of protein, essential amino acids, and starch in the grain.
