Genetic diversity of Japonica rice varieties based on SSR markers

LIU Wei~(1,2),LI Zi-chao~2,SHI Yan-li~1,MA Hong-wen~1,WANG Jian~1,ZHANG Hong-liang~2(1.The Crop Research Institute of Ningxia Academy of Agricultural and Forestry Sciences,Ningxia Yongning 750105,China;2.Department of Plant Genetics and Breeding,China Agricultural University,Beijng 100094,China)  
Thirty-seven SSR(simple sequence repeats)were used to study genetic diversity among 72 Japonica rice varieties.The average number of alleles per locus was 5.1 with a range from 2 to 11.UPGMA cluster analysis showed that all cultivars could be classified into 7 groups,which generally agreed with ecotypes.And this indicated SSR markers play an important role in ecotype classification and study of genetic diversity.Consequently,SSR markers could be used as a useful tool for measuring genetic diversity,assigning rice to geographical distribution,and analysing its ecotype.
