A genome-wide association study (GWAS) was performed using a high-density infinium 90K SNP array. We identified a total markers traits associations (MTAs) (p ?0.000) for the following plant traits; days taken to 50% heading(DH), days to 50% maturity (DM), plant height (Ph) cm, flag leaf area cm2 (FLA), tillers number per plant, spike length (SL) cm and grain yield per plant (GP) g. Most of the SNPs were identified in the A and B genome as compared to the D genome. The significant associated SNPs were mainly distributed on the chromosome 2B, 3B, 5A, and 5B. Nine SNPs on chromosome 5A, 2B and 2D were identified having pleiotropic effects The correlation analysis showed a significant positive association among SL, NT, GP. Which depicted that these traits are promising for breeding high yielding wheat cultivars. This study provided useful information of the valuable genetic loci for marker-assisted breeding.
