摘要
应用SDS -PAGE技术 ,分析了 2 4份四川小麦新品系的高分子量谷蛋白亚基 ,并计算其品质得分。结果表明 :大部分品系的Glu -A1位点上具有 1亚基 ,Glu -D1位点上 5 +1 0亚基达 75 % ,但Glu -B1位点上的 7+8或 1 7+1 8亚基比例较低。所有品系的品质得分为 4～ 1 0分 ,平均 7 7分。
The grain proteins of 24 advanced wheat lines Bred in Sichuan were fractionated by SDS-PAGE to determine their high molecular weight glutenin subunit compositions. And the quality score of each genotype was calculated. The results indicate that the majority of the genotypes carry subunits 1 encoded by Glu-A1, on Glu-D1, 75% genotypes possess subunits 5+10. But on Glu-B1, few genotypes possess subunits 7+8 or 17+18. The quality scores of all genotypes range from 4 to 10. The mean score in these advanced lines is 7 7. The result suggests that the quality of Sichuan wheats has achieoed get some progress.
