| Abstract: | The grain proteins of 24 advanced wheat lines Bred in Sichuan were fractionated by SDS-PAGE to determine their high molecular weight glutenin subunit compositions. And the quality score of each genotype was calculated. The results indicate that the majority of the genotypes carry subunits 1 encoded by Glu-A1, on Glu-D1, 75% genotypes possess subunits 5 10. But on Glu-B1, few genotypes possess subunits 7 8 or 17 18. The quality scores of all genotypes range from 4 to 10. The mean score in these advanced lines is 7 7. The result suggests that the quality of Sichuan wheats has achieoed get some progress. |
