Assessment of genetic diversity of some commonly grown rice genotypes of South Bengal using microsatellite markers associated with the saltol QTL mapped on 1"chromosome

Abstract

A total of 16 common rice lines and one wild rice relative grown in rarh south Bengal were genotyped using six polymorphic microsatellite markers associated with saltol QTL mapped on rice chromosome. DNA fingerprint profiles identified each of the 17 rice genotypes unequivocally and the pair-wise polymorphism data for the studied genotypes were used to analyze the genetic diversity present within the studied rice lines. The number of alleles per SSLP marker, the size range of the PCR products and the polymorphism information content (PIC) values of each marker were calculated out. A dendrogram was constructed using the average linkage (within group) and similarity coefficient among the studied genotypes which indicated that a considerable amount of genetic diversity is present and classify the studied genotypes into two major clusters and one minor cluster.
