Comparative Evaluation of Rice SSR Markers on Different Oryza Species

The growing number of rice microsatellite markers permit a comprehensive comparison of allelic variation among the markers developed using different methods, with diverse repeat motifs and at variable genomic regions. Under this study, comparison between a set of 67 microsatellite markers representing the whole (twelve) rice chromosomes was done over worldwide collections of nine species of the genus Oryza. These SSR markers were evaluated for the genetic parameters such as; number of alleles amplified per primers, observed heterozygosity, gene diversity, rare allelic frequency and Polymorphic Information Content (PIC) values.
