According to the experimen- tal results, by using polymorphic SSR primer 455, the amplified bands of female and male parents were 460 and 430 bp, respectively; by using polymorphic SSR primer 478, the amplified bands of female and male parents were 330 and 350 bp, respectively. The identification results of Xinkui 19 hybrids and its parents with SSR marker technique and field cultivation were basically consistent. SSR primers 455 and 478 could be used for rapid and effective identification of the purity of Xinkui 19 hybrid seeds.展开更多
