Abstract

Abstract:

The high molecular weight glutenin subunit(HMW-GS) composition and the swelling index of glutenin(SIG) of 49 spring wheat varieties in Qinghai province were determined to assess the genetic diversity of Glu-1 loci and the quality of the spring wheat. 15 HMW subunit patterns were observed. For the Glu-1 loci, 13 alleles were detected: 2 at the Glu-A 1 locus, 7 at the Glu-B 1 locus, and 4 at the Glu-D 1 locus. Statistic analysis revealed the necessity of improving the poor quality of spring wheat in Qinghai province.

Key words: spring wheat, genetic diversity, high molecular glutenin, swelling index of glutenin
