利用A－PAGE方法对小麦（黑麦）异源重组系异源2号组配的22个强优势杂交组合的亲本进行了醇溶蛋白分析。结果表明，醇溶蛋白图谱能将除绵农2号和绵农3号外的所有亲本区分开。电泳共分离出44条相对迁移率不同的谱带。其中，37条具多态性，每个材料可分离出17～27条谱带。父本异源2号与其强优势组合母本间醇溶蛋白遗传距离相对较小，平均值为0．34。根据醇溶蛋白遗传距离聚类结果，1B／1R和非1B／1R易位系被分别聚在不同（亚）类中，多数系谱相同或相近的品种（系）能被聚在一起。醇溶蛋白遗传距离与亲本各性状表型差异及F1杂种优势间相关均不显著，难以用于预测杂种优势。
The prolamins were analyzed by A-PAGE in 22 parents with strong heterosis of heterologous recombination lines of wheat (rye). The results showed that gliadin profiles could distinguish all parents except Menongnong 2 and Miannong 3. A total of 44 bands with different relative mobility were isolated by electrophoresis. Of these, 37 were polymorphic with 17-27 bands per material. The genetic distance of gliadin between male heterotic 2 and its dominant parent was relatively small with an average of 0.34. According to the result of gliadin genetic distance clustering, 1B / 1R and non-1B / 1R translocations were clustered in different sub-species respectively. Most cultivars with the same or similar pedigree could be clustered together. The correlation of gliadin genetic distance with phenotypic differences in F1 traits and F1 heterosis was not significant and it was difficult to predict the heterosis.
