摘要
SSR标记由于具有数量丰富、多态性高、遗传上呈共显性、实验操作简单、结果稳定可靠、引物序列易交流等优点,已成为杂交水稻种子纯度鉴定的一种理想分子标记。概述了SSR分子标记技术应用于杂交水稻种子纯度鉴定的原理、技术要点及其研究进展,并就该技术产业化应重点考虑的问题进行了讨论。
SSR （Simple Sequence Repeat） has become a very useful kind of molecular markers for the purity identification of hybrid rice seeds in recent years, especially for the differentiation of closely-related varieties because it is abundant in number, high in polymorphism, co-dominant in genes, simple in experimental operation, reliable in results and easy in exchange of primer sequences. The mechanism, key technical points and research progresses of applying SSR markers on the purity identification of hybrid rice seeds were summarized, and the issue to be considered in the commercialization of this technique was also discussed.
