Abstract:In order to study the widely adaptation and detect the genetic diversity of Abodanza（Triticum.aestivum L.） in the different ecological area of Qinghai ,subunits composition of high mplecular weight gluten with 15 Abodanza were analyzed by means of SDS- PAGE. The results were described as following: A total of 8 allele combinations were observed in the 15 Abodanza and the predominant type was 1，7+8 and 2+12；there were 11 alleles on Glu-1 locus with the frequencies varied from 6.67% to 100%；The values of D of the Glu-B1 loci were higher and Glu-B1 loci has abundant genetic diversity. The result showed that genetics similarities ranged from 0．35 to 1 with an average of 0.675. All materials were divided into 3 groups and 13 wheat materials Abodanza were clustered into the first group while another two materials were respectively clustered into the second group and the third group .These results indicated that Abodanza materials have abundant genetic diversity.
