摘要:

为了解青海省春小麦 Glu-1 位点的遗传多样性及其品质状况,检测了49个青海省代表性春小麦品种的高分子量麦谷蛋白亚基(HMW-GS)组成情况,并测定了每一品种的谷蛋白溶胀指数.共检测出15种高分子量麦谷蛋白亚基组合类型.在 Glu-1 位点检测到13种等位变异,其中 Glu-A 1 位点2个、 Glu-B 1 位点7个、 Glu-D 1 位点4个.实验数据表明,青海省春小麦品质较差,尚待改进.

关键词: 春小麦, 遗传多样性, 高分子量麦谷蛋白, 谷蛋白溶胀指数

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
