Molecular approach to characterization of rice landraces of Eastern India with SSR markers

Abstract :

Rice, a model for cereal genomics, is the first crop genome to be sequenced. The present investigation aims at finding out the genetic diversity of seventeen elite rice cultivars of important agro–morphological traits for improved grain quality and higher grain yield using 10 SSR markers revealing high level of polymorphism among the landraces. A total of 22 scorable alleles were generated among the genotypes. The number of alleles produced by different primers ranged from two to three with an average of 2.2 alleles per locus. Cluster analysis categorized the cultivars into 6 clusters. The similarity coefficient ascertained through Jaccard�s analysis revealed that genotype Gobindobhog and Jhingasail were more genetically diverged from the rest landraces. This study would benefit plant eeders, researchers providing useful information for selecting suitable parental genotypes for future crop improvement program and also in molecular eeding.
