小麦高分子量谷蛋白亚基的遗传特性研究

Study on Genetic Characteristics of High Molecular Weight Glutenin Subunit(HMW-GS) in Wheat

利用聚丙烯酰胺凝胶电泳(SDS-PAGE)方法,在蛋白质水平上对多个亲本及其杂交获得的正反交F1代杂交籽粒进行小麦高分子量谷蛋白亚基(HMW-GS)分析,研究其遗传规律。结果表明:小麦高分子量谷蛋白亚基具有品种特性,表达受遗传控制,不受环境影响;小麦高分子量谷蛋白亚基在F1代有些组合呈共显性,有些组合呈倾母性的遗传特性。

The genotypes and genetic rule of high molecular weight glutenin subunit （HMW-GS） in wheat were conducted by SDS-PAGE in protein levels. The results indicated that the band patterns of HMW-GS were controlled by wheat genes and they were not affected by environmental factors. The parents transmitted all HMW-GS to the hybrid F1 in some cross combinations, and the female parent affected significantly in inheritance in hybrid F1 in anothor cross combination.
