Abstract: Inorder to study quality differences and inheritance of Glu-1A Alleles mutant of wheat induced by[60Co]γ-ray,with 300 Gy of[60Co]γ-ray radiation of dry wheat seeds of Wanmai 50,and with method of analysis of near infrared and SDS-PAGE,quality evaluation and differences was made and inheritance of Glu-1A Alleles mutant was studied.The results showed that one HMW-GS mutant was screened in M2,Glu-1A subunit component changed from Glu-1ANull to Glu-1A1,and the mutation ratio was 0.15%.The quality traits of the mutant Wanmai 50 in F2 had transgressive phenomena.There was significant correlation between quality score and water absorption,hardness and sedimentation.The HMW-GS of orthogonal and reciprocal cross of F1 all showed double dominance of Glu-A1.The ratio of Glu-1A1 to Glu-1ANull was in line with 1:1 segregation rule in side-crosses,and was in line with 3:1 in F2. In conclusion,the protein content of mutant increased,the hybrids had super-pro-quality,and the inheritance accorded with the Mendelian inheritance and free combination.
