摘要： 本文对小麦种质资源中古老品种的麦谷蛋白高分子量(HMW)亚基的构成进行了分析,并与其它的研究结果作了比较.随育种历史的发展,Glu-Alb、Glu-Blb、Glu-Ble和Glu-Dl2的频率降低;Glu-Ala、Glu-Bla、c、d和Glu-Dld的频率增加;其它等位基因频率无大的变化.在澳大利亚小麦品种中,和烘烤品质关系密切的Glu-Ala、Glu-Bli和Glu-Dla的频率比古老小麦品种高,这反映了上述三个等位基因对澳大利亚小麦优异烘烤品质的贡献.我国小麦品质育种也应充分利用它们;另一个类似的等位基因Glu-Blb也有待进一步开发利用.

Abstract: The allelic composition of the three loci controlling HMW glutenin subu-nitsof a total of 2064 varieties from the "old"wheat collections was studies,and the comparison of the present results to those of the other studies was carried out. As the wheat varieties had been improving, the frequences of Glu-Alb, Glu-Blb, e and Glu-Dla decreased, the frequences of Glu-Ala, Glu-Bla,c,d and Glu-Dld increased, no change occurred for the other alleles in frequence. Glu-Ala, Glu-Bli and Glu-Dld assessed as being good contributors to bread-making quality were in higher frequence in Australian cultivars than the "oid" wheat collection, showed that those three alleles contributed to good breed-making quality of Australian wheat. More attention should be paid to the Glu-Blb in the future research and breeding programs.
