中文摘要:
      采用SDS-PAGE技术对陇东旱塬地区育成的小麦品种(系)的HMW-GS的遗传变异进行了研究。结果表明:20份材料中HMW-GS有8种,分别为:Null、1、2*、7+8、7+9、5+10、2+10;亚基组成以Null、7+8、2+12(40%)和Null、7+9、2+12(30%)为主,大部分缺乏5+10,1, 17+18,14+15等优质亚基。优质亚基(1、7+8、5+10)在地方品种白齐麦和早先育成品种庆丰1号中出现,而在近年育成的品种中却没有出现,在今后小麦育种中应加强对这2个优质亚基的应用。
英文摘要:
      The genetic variation of High Molecular Weight of winter wheat varieties was studied by SDS-PAGE in Longdong dryland. Totally 8 subunits are detected from 20 materials, including Null, 1, 2*, 7+8, 7+9, 5+10, 2+10. The result indicates that the main subunit Composition are Null, 7+8,2+12(40%) and Null, 7+9, 2+12(30%). Most of wheat varieties are lack of high-quality subunits of 5+10,1,2*,17+18,14+15. Qing Feng No.1 and Baiqi wheat contain high-quality subunits(1、7+8、5+10) can be found, but in recent years these high-quality subunits can’t be found among bred wheat varieties. During wheat breeding in the future, the application of these two high quality subunits should be strengthened.
