Abstract
The endosperm storage proteins of 44 Sichuan wheat varieties released in 2001-2005 were fractionated by SDS-PAGE to determine their high molecular weight glutenin subunit(HMW-GS) composition.Sixteen pattern of subunits and ten alleles were identified,two alleles at Glu-A1 locus,five alleles at Glu-B1 locus,and three alleles at Glu-D1 locus.The most common pattern of subunits were N,7+9,2+12 and 1,20,2+12,their occurrence frequencies were 15.9 % and 13.6 %,respectively.The glutenin quality scores ranged from 4 to 10,with an average of 6.9,except a novel pattern of subunits(N,20,5+12).
