Abstract

Seventy genotypes of soybean along with seven mutants were evaluated by eight SSR markers of reported putative associations with QTLs for Rust, Rhizoctonia root rot, Purple seed stain and Sudden death syndrome resistance. A total of 58 (57 polymorphic) alleles were detected by SSR markers. Correlation analysis revealed that range of allele size was significantly associated with alleles per locus (r = 0.551, P <0.01). These markers were unable to discriminate the genotypes on the basis of the trait these mapped, but it was concluded that there was abundant SSR polymorphism, and this would enable pyramiding of disease resistant genes into one variety.
