SELECTION OF GENOTYPES WITH HIGH GRAIN QUALITY FOR SELECTION-GENETIC RESEARCH FROM SYNTHETIC HEXAPLOID WHEAT LINES
In this study, grain quality parameters of synthetic hexaploid wheat lines were studied and compared with released varieties. According to the results, the highest protein and gluten content were recorded in the genotypes Ukr-Od 952.92/Ae.Squarrosa (34), Ukr-Od 952.92/Ae.Squarrosa (31), Aisberg/Ae.Squarrosa (103)//Demir, Pandur/Ae.Squarrosa (84), Ukr-Od 1530.94/Ae.Squarrosa (48), Ukr-Od 952.92/Ae.Squarrosa (37), and Pandur/Ae.Squarrosa (87). It was determined that synthetic wheat lines had 28.5% higher protein content and 5.5% higher gluten content compared to the released varieties
