| 摘 要： | 应用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)方法,分析了196份甘肃省冬小麦资源的高分子量麦谷蛋白亚基(HMW-GS)组成。结果表明,甘肃省冬小麦资源的亚基组成较丰富,共检测到13种亚基变异类型和21种亚基组合类型。地方品种的亚基组合类型以Null、7+8、2+12为主;育成品种的亚基变异类型比地方品种丰富,并且各种组合类型相对分布均匀。供试材料的HMW-GS品质评分在5～12分之间,平均得分6.8。丰富遗传资源,提高小麦优质亚基的分布频率是今后小麦品质育种的主要方向。

| Abstract: | The composition of high-molecular-weight glutenin subunits(HMW-GS) in 196 varieties was analyzed by using SDS-PAGE method in this study.The results showed that winter wheat germplasm had plentiful HMW-GS types,thirteen subunits and twenty-one subunits combination were detected.The subunits of N,7+8,2+12 are major type in local varieties.The combined types have plentiful numbers and proportioned distributions in bred varieties.The HMW-GS quality scores of the tested varieties rang from 5 to12,with an average... |
