多小穗小麦品系10-A及其改良系的醇溶蛋白分析

Gliadin Analysis of Multispikelet Wheat Line 10-Aand Its Recombinants

应用酸性聚丙烯酰胺凝胶电泳（MAGE）分析了多小穗小麦10－A及其亲本、以及来源于三交组合10－A／88－1643／／川育12号的89个稳定品系的醇溶蛋白。结果表明，10－A的醇溶蛋白均来源于其亲本，但更与雅安矮10号相似。10－A、88－1643和川育12号的醇溶蛋白带纹各不相同，能彼此区分。在89个后代品系中，出现了3种亲本类型、4种重组类型和1种突变类型，突变率为1．10％。同时，还讨论了Gld1B3位点与多小穗的关系。

The gliadin patterns of multispikelet wheat line and its recombinants were analyzed by using acid polyacrylamide gcf electrophoresis (APAGE). The Gli alleies of 10-A comes fromits parents Yaanai 10, Qinling rye and Aurora, but it is more similar to Yaanai 10. From the gliadin patterns, 10-A, 88-1643 and Chuanyu 12 are identified by each other. In the 89 linesderived from triple cross 10-A/88-1643
