Diversity analysis of the rice cultivars (Oryza sativa L.) by utilizing SSRs rice diversity by SSRs

摘要

This study was carried out to analysis of genetic diversity of rice marketed in Turkey.Sixty rice varieties used as a material. A total of 50 SSR markers distributed to all12 rice chromosomes were used for the diversity analysis of the genotypes. Out ofthese, 43 SSRs produced clear, distinct polymorphic bands among the rice varieties,and a total of 227 alleles were obtained. The number of alleles per locus ranged from9 to 1. The mean number of alleles per locus was 5.25, and 22 markers (51%) had 6or more alleles. Clustering of 60 varieties based on 43 SSR markers was carried out.While aromatic varieties were placed into an out-group Rocca and Baldo which areparents of many rice varieties and 47 varieties were placed into the same clusters.This SSR polymorphism analysis revealed genomic relationships in rice marketed inTurkey.
