Abstract: Low-molecular-weight glutenin subunits (LMW-GS) are closely related to processing quality of wheat.The alleles on Glu-A3,Glu-B3 and Glu-D3 loci of low-molecular-weight glutenin subunit in 356 wheat varities(lines) from South Yellow and Huai Valley Facultative Wheat region in China were detected by STS molecular markers and SDS-PAGE to improve wheat quality.It turned out that:There were 15 kinds of allelic variations in 356 detected varieties.The frequencies of the allelic variations of Glu-A3a,Glu-A3b,Glu-A3c and Glu-A3d at Glu-A3 locus were 12.1%,13.5%,41.0%,33.4%,respectively;the alleles of Glu-B3a,Glu-B3b,Glu-B3d,Glu-B3f,Glu-B3g,Glu-B3h,Glu-B3i and Glu-B3j at Glu-B3 locus were 8.71%,8.99%,23.0%,5.90%,7.30%,3.65%,0.28%,42.1%,respectively;and the alleles of Glu-D3a,Glu-D3b and Glu-D3c at Glu-D3 locus were 40.2%,29.8%,30.0%,respectively.The highest frequency of the subunit combination at Glu-3 was Glu-A3c/Glu-B3j/Glu-D3a (10.7%).Transformating and pyramiding superior subunits can be helpful in Chinese wheat quality improvement.
