关于小麦体细胞无性系变异前人已做了大量的研究,观察到了形态学、细胞学和生化特性变异.对醇溶蛋白和谷蛋白变异的分析,获得了基因突变的证据,但不知突变基因的位点.本研究的目的在于分析体细胞无性系的高分子量谷蛋白亚基(high-molecular-weightglutenin subunits,HMW-GS)的变化,获取特定基因(Glu-l)突变的证据,并研究HMW-GS变异体农艺性状和产量性状的表现.
A great deal of research has been done on the clonal variation of somatic clones of wheat and morphological, cytological and biochemical variations have been observed. The analysis of the variations of gliadin and gluten obtained evidence of the mutation, but we did not know the mutation The purpose of this study was to analyze the changes of high-molecular-weight-glutenin subunits (HMW-GS) in somatic clones and to obtain evidence of the mutation of a specific gene (Glu-1) Performance of agronomic traits and yield traits of HMW-GS variants.
