  1. QTLs were obtained by grouping associated SNPs with overlapping LD windows (LD_win) for the three traits (DTA male flowering time, PlantHT plant height, GY grain yield). “Marker Nb” indicates the number of markers tested in GWAS. “Total number”: is the sum of associated SNPs or QTLs across environments. “Average per envir” indicates the average number of QTLs obtained in 22 environments for three traits (66 trait-environments combinations)
