IDENTIFICATION OF HMW GLUTENIN POLYMORPHISM IN VARIETY SAMPLES FROM COLLECTION AND BREEDING NURSURIES OF WINTER WHEAT
Abstract
The analysis of polymorphism of such genes as Glu-А1x, Glu-B1x and Glu-B1y, Glu-D1x and Glu-D1y controlling synthesis of storage seed proteins (glutenins) was conducted in 45 variety samples of winter wheat. Probable bread-making qualities of the studied lines were estimated. The test results of Belarusian wheat samples showed that among them, a high share of allels in Glu-А1 and Glu-В1 loci influencing the bread-making qualities negatively, and d allel in Glu-D1 locus contributing positively to flour quality, was observed. As a result of the researches conducted, genotypes containing favourable combinations of the alleles of high-molecular-weight glutenins were isolated. 4 variety samples with the highest indices of breadmaking qualities (10 points) were found out. The lowest overall breadmaking estimate was in the variety samples in which parents were only West-European varieties, such as STH 729, STH 735, Kubus, Kriss, STH 583, STH 1198, Kontur, Kornet, and as well as when Belarusian varieties with low bread-making qualities (Schara and Garmoniya) were used.
