Storage Proteins Analysis of Three Wheat Cultivars with Different Quality Character in Sichuan, China

By using SDS-PAGE and APAGE, the author analyzed the glutenins and gliadin patterns of 3 Sichuan wheat cultivars Mianyang 19, Chuanyu 12 and Chuannongmai 1, which have different quality cheracters. The results are as follows: ①The wheat quality is not only determined by HMW-glutenins, but also affected by the LMW-glutenins and gliadin. Those with good subunits 5+10 do not necessarily have good bread-making quality; ②All the gliadin and HMW-glutenin subunits were totally expressed in F_1 generation. It indicated that the gliadin and HMW-glutenin are inherited as codominant; ③The gliadin and HMW-glutenin patterns are not affected by the seed mature grade and light germination.
