Assessment of genetic diversity among twenty Indian wheat (Triticum aestivum L.) cultivars using simple sequence repeat (SSR) Markers

Bread wheat is most cultivated cereal used as food over 95% of the population. Twenty wheat genotypes were assayed to study the genetic diversity using molecular markers. The seventy-five alleles were identified with a mean of 2.34 alleles per locus using 32 SSR markers. Majority of SSR markers showed a high level of polymorphism. PIC values ranged from 0.05 (WMS-169) to 0.75 (CWM-107), with an average of 0.38 per primer. The RP value of primer ranges from 0.92 (WMC-177) to 1.94 (WMS-169) with an average value of 1.51, which explains the ability of primers to resolve the studied germplasm.
