杂交水稻万象优982品种真实性鉴定

Authenticity Identification of Hybrid Rice Variety Wanxiangyou 982

本文采用48对SSR分子标记对3份待测样品(自种子销售市场取回)和标准样品万象优982(江西红一种业科技股份有限公司提供)进行了比较。结果表明,2号待测样品与标准样品间仅有1对引物的扩增条带存在差异,判定为“近似品种”。采用48对SSR分子标记对杂交水稻真实性进行鉴定,不仅可为打击非法制售假劣种子及品种套牌侵权等行为提供依据,而且有利于提高种子管理与执法部门的市场监管效率。

In this paper,three samples(retrieved from the seed sales market)and standard sample Wanxiangyou 982(provided by Jiangxi Hongyi Seed Science&Technology Co.,Ltd.)were compared by using 48 pairs of SSR molecular markers.The results showed that only one pair of primers had different amplification bands between the sample 2 and the standard sample,which was judged as"similar variety".Using 48 pairs of SSR molecular markers to identify the authenticity of hybrid rice can not only provide a basis for combating illegal production and sale of fake seeds and infringement of variety licensing,but also help improve the efficiency of market supervision of seed management and law enforcement departments.
