摘要
用SDS聚丙烯酰胺凝胶电泳分析了我国50个主要冬小麦推广品种的高分子量麦谷蛋白亚基组成,据Payne等方法计算了其品质得分。结果表明,我国冬小麦推广品种的高分子量麦谷蛋白亚基构成欠佳,主要原因在于5+10亚基少,2+12亚基多;1或2~*亚基少,N类型多等。本文中还讨论了我国冬小麦品质育种的策略和方法。
The grain proteins of 50 China-grown winter wheat cultivars were fractionated by SDSpolyacrylamide gel electrophoresis to determine their high molecular weight glutenin subunit com-position. Using the method described by payne (1987), the quality scores of each of the subunitswere summed to create a Glu-1 quality score for each cultivar. The results indicated that China-grown winter wheats have rather low Glu-1 quality scores. It was the most important reason thatthe frequency of subunits 5+10 was very low. The results were discussed in relation to futurestrategies for improving bread-making quality of China winter wheat cultivars.
