Eighteen rice hybrids and their parents were chosen to identify the hybrids' purity with SSR markers and phenotype. The two methods of purity identification were compared in order to research the availability and accurateness of SSR marker identifying the rice seed's purity .The results as follows:
1. Eighteen rice hybrid parents' DNA were amplified by twenty SSR markers, one or four SSR primers performed polymorphism between the double parents to average every hybrid.
2. N...
