摘要
在小麦无性系变异的研究中,发现了一份冀92-3235HMW-GS的2+12亚基缺失的材料,通过进一步选择,选育成了稳定遗传的7份材料,其在农艺性状上与对照冀92-3235基本相同,SDS PAGE电泳图谱仅在Glu D1位点上有差异,醇溶蛋白电泳显示也完全相同,品质分析结果表明它们的面粉品质发生了很大变化,其湿面筋无法检出、沉降值显著下降,从而说明2+12亚基对小麦品质有较大影响。
In the process of study on wheat asexual stains,a material without HMW-GS 2+12 subunit, Ji 92-3235 was found.By further selection, seven stable materials in heredity characteristics were obtained. Between the seven materials and the contrast, Ji 92-3235,but there were less difference in agriculture traits and gliadin typing in electrophoresis,but there were obvious difference on the Glu-D1 in SDS-PAGE and flour quality analysis, the subside value in the seven materials is lower, and the wet gluten could not be deter mined. From the results, we can see the HMW-GS have important effect on the wheat quality.
