利用染色体配对分析和酯酶及种子醇溶蛋白电泳分析研究了我国育成的１１个八倍体小偃麦，结果表明：（ａ）来源于小麦和中间偃麦草杂交后代的６个部分双二倍体中，中１和中２的偃麦草染色体组不同于中３、中４、中５和小偃７８８２９的偃麦草染色体组；（ｂ）来源于小麦和长穗偃麦草杂交后代的５个部分双二倍体中，小偃７８４的偃麦草染色体组不同于小偃６９３和小偃７６３１中的偃麦草染色体组，表明在长穗偃麦草中有两个互不相同又不同于小麦的染色体组Ｅ和Ｆ，而小偃７４３０和小偃６８中的偃麦草染色体组很可能是Ｅ和Ｆ染色体组的重组体；（ｃ）小偃７８４中的长穗偃麦草染色体组和中５及小偃７８８２９中的中间偃麦草染色体组基本相同，而中２的中间偃麦草染色体组不同于小偃６９３和小偃７６３１中的长穗偃麦草染色体组Ｆ，这意味着在长穗偃麦草和中间偃麦草中可能只有一个共同的染色体组Ｅ。部分双二倍体中酯酶及醇溶蛋白偃麦草染色体特征带的存在和发现，为这些染色体或其片段导入小麦后的鉴定提供了方便。
Chromosome pairing analysis and esterase and seed prolamin electrophoresis analysis of 11 bred tritici in China showed that: (a) Twelve-fold doubling of the six parts derived from crossing progenies of wheat and wheat In the body, the genomes of Chlorella pyrrhoti in Zhong 1 and Zhong 2 were different from that of Chromosome 3 in Zhong 3, Zhong 4, Zhong 5 and Xiaoyan 78829; (b) Five parts Among the diploid diploids, the chromosome group of Agropyron chinense 784 was different from the genomes of Agropyron chinensis in Xiaoyan 693 and Xiaoyan 7631, indicating that there are two genomes in T. elongate that are different from each other and distinct from wheat E and F, while the genomes of Elytrigliaceae in Xiaoyan 7430 and Xiaoyan 68 are likely to be recombinants of E and F genomes; (c) The genomes of Eulophilia elongatum in Zhongyou 784 and Zhongyao 5 and Xiaoyan Thinopyi medium chromosome 78829 genome is basically the same, and the middle 2 Thinopyrum intermedium chromosome group is different from Xiaoyan 693 and Xiaoyan 7631 in the long-tailed Thinopyrum Peer group F, which means E.elongata and Thinopyrum may be a common genome E. The presence and discovery of partial diploid esterase and prolaminum chromosomal bands provide a convenient marker for the identification of these chromosomes or their introduction into wheat.
