Research Progress on Agricultural Biotechnology Utilizing in Purity Identification of Rice Seed

Abstract

Abstract: 【Objectives】To select one technique to identify rice seed purity which was direct, accurate, reliable, economical and simple to manipulate.【Methods】the research and utilizing status of rice seed purity identification by electrophoresis, DNA molecular markers and leaf-color marker were analyzed and summarized in the paper.【Conclusion】It was considered that techniques of rice seed purity identification by electrophoresis and DNA molecular markers can only obtain the data of hybrid seed purity but distinguish the not real hybrid seed, consequently no measures to deal with the low yield due to low hybrid seed purity. The utilization of leaf-color marker of white to green will end the traditional techniques and lead to revolution of seed purity identification, which have a broad utilization in the practice.
