采用农业部推荐的12对水稻SSR引物（ NY/T 1433-2007），对2008年以来由浙江省主要育种单位育成的46个常规粳稻品种构建DNA指纹图谱，并分析其亲缘关系。结果显示，12对SSR引物共检测出84个等位基因，平均多态性频率（ FP）值为0.192。46个品种的相似系数在0.735～1.000之间，平均相似系数为0.879，表明近年来浙江省粳稻品种亲缘较近，遗传背景较狭窄。该研究结果可为浙江省水稻新品种选育、鉴别和保护提供参考。

In order to provide references for rice breeding in Zhejiang Province , 12 pairs of rice SSR primers recom-mended by Ministry of Agriculture ( NY/T 1433-2007 ) were adopted in the present research to construct DNA fin-gerprints for 46 japonica rice varieties bred in Zhejiang Province since 2008 , as well as to analyze their genetic rela-tionship.It was shown that 84 alleles were detected by 12 pairs of SSR markers , and the average frequency of poly-morphism ( FP) was 0.192 .The similarity coefficient of 46 cultivars was between 0.735-1.000 with an average of 0.879 , which indicated a close affinity among the tested cultivars and a narrow breeding background in Zhejiang Province.
