摘要
本文从创制的８０ 个新选系中鉴定出１２ 个抗白粉病品系，应用醇溶蛋白Ａ－ ＰＡＧＥ 检测发现其中９ 个为１ＢＬ／１ＲＳ易位系。麦谷蛋白亚基ＳＤＳ－ ＰＡＧＥ 分析表明，有３ 个含５ ＋ １０ 优质蛋白质亚基。综合农艺性状表现评定出９８ －１２３６ 和９８－ １２６６ 两个品系表现优异。进一步对籽粒主要品质性状检测表明，这两个品系均优于对照品种川麦２８ 号。
The 12 lines with resistance to powdery mildew were selected from 80 new breed lines. Results of APAGE analysis shows that 9 of them carried 1BL/1RS translocation. The HMW GS pattern analysis of the 9 lines indicates that 3 lines have the 5+10 HMW GS, which is considered having a positive effect on bread baking quality. By the evaluation of most of agronomic performance, 2 lines (98-1236 and 98-1266) are regarded as excellent lines. Furthermore, Comparing with chuanmai 28,the 2 lines have better major quality characters.
