Number (no.) of QTL, proportion of explained phenotypic variance before (R2adj) and after cross validation (R2CV) and genotypic (pG) variance for each of 220 testcross progenies in two populations (Pop-A, Pop-B) estimated across ten (plant height and yield-related traits) and six (quality-related traits) environments.
