Assessment of Genetic Diversity Using SSR Markers in Some Rice Genotypes

Abstract

A study was conducted at the Institute of Plant Breeding, Seed
Science and Population Genetics, University of Hohenhiem, Stuttgart,
Germany, during 2008 to assess genetic diversity among 17 rice
genotypes by using 36 SSR markers. All the primers showed
polymorphism. A total of 320 alleles was detected at the markers loci
across the rice genotypes. The mean number of alleles per locus was 8.8.
Cluster analysis grouped the rice genotypes into 5 major groups as the
genotypes that are derivatives of a genetically similar type clustered more
together. These genotypes represented a valuable source of diversity
which can be used in the breeding programmes.
