Open publisher page 1 citations

Abstract

It was found in the SDS-PAGE detection of 78 shares of wild emmer from Israel that their high molecular weight glutenin subunits(HMW-GS) had higher genetic diversity.On the loci of Glu-A1 and Glu-B1 2,there were 22 types of subunit variation totally,which could be confirmed,in which the subunits 1 and 2* on A locus and subunits 7+8,13+16 and 17+18 on B locus were high-quality subunits(Their occurrence frequencies were 7.69%,8.97% and 5.13% resp.).Simultaneously,there occurred the subunit 1Ay which was not expressive in common wheat and many peculiar subunit types which was rare or lack in common wheat,such as 1*,7*+8*,7*+9,7+8*,7+9* and 17+18 etc.And 7 new and unnamed subunit types occurred in 12 shares of materials.
