چکیده

This study was carried out to evaluate the genetic diversity and relationship between different rice populations (Local, Import & Breeding rice populations) with 25 microsatellite loci. The results revealed that all the primers showed polymorphism among the rice populations. A total of 164 alleles were detected. The number of alleles per marker ranged from 3 to 14 with an average of 6.56 alleles per locus. Result from UPGMA analysis clustered the different rice populations into Local, and Import-Breeding rice groups. Import rice populations were found to have the highest genetic diversity (0.831±0.445) while, the lowest were in Local rice populations (0.616±0.319). Genetic distance was estimated 0.213 between Local and Breeding rice populations and 0.038 between Import and Breeding populations. The result indicates that SSR markers possess suitable potential for recognizing and classifying rice populations
