Abstract

In order to identify glutenin subunit composition in common wheat in Jiangsu province,seventy-seven cultivars or advanced lines from south Huai River wheat region( SHRWR) and north Huai River wheat region( NHRWR)were used to investigate the allelic variation of glutenin subunits by SDS-PAGE. Abundant veriations of high molecular weight glutenin subunit( HMW-GS) and low molecular weight glutenin subunit( LMW-GS) was detected at loci Glu-1 and Glu-3. The number of allelic subunit at Glu-A1,Glu-B1,Glu-D1,Glu-A3 and Glu-B3 were three,five,four,five,and six,respectively. Polymorphism of HMW-GS in NHRWR was higher than that in SHRWR. The frequency of allelic variation differred at Glu-1 and Glu-3 and in SHRWR and NHRWR,with the high quality subunits accounting for the minority. The high-frequency subunits were ‘ 0 '
