原始语种摘要: Genetic variability of broad range of cereal crops may lead to reduction in the yield under abiotic and biotic stresses. In present study Genetic diversity of the twenty wheat ( Triticum aestivum L.) varieties was analyzed at the DNA level using 19 simple sequence repeats (SSR) markers. The wheat 16 SSR markers out of 19 had detected 40 alleles with an average of 2.5 alleles per primer. The number of alleles per primer ranged from 1 to 5. The resolviong power (Rp) of each primer ranged from 1.0 for the CWM119 to 5.2 for XGWM-293-7A with an average of 2.46. The gene diversity based on SSR markers was ranged from 0.36–0.88 with an average value of 0.62. The similarity coefficient values and dendogram revealed that genotype HD 2177 and HUW 37 have lowest similarity and HD 2177 and K 9533...
