Genomic regions governing days to heading (DH), grain filling duration (GFD), number per spike (GNPS), weight (GWPS), plant height (PH), and yield (GY) were investigated in a set of 280 diverse bread wheat genotypes. The genome-wide association studies (GWAS) panel was genotyped using 35K Axiom Array phenotyped five environments. GWAS analysis showed total 27 Bonferroni-corrected marker-trait associations (MTAs) on 15 chromosomes representing all three subgenomes. GFD the highest MTAs (8), followed by GWPS (7), GY (4), GNPS (3), PH DH (2). Furthermore, 20 identified with more than 10% phenotypic variation. A stable (
