A "which wins where or which is best for what" genotype plus genotype x environment interaction biplot of grain yield for 16 early maturing maize cultivars evaluated at six locations under Striga infestation in west and central Africa in 2002. Principal component (PC)1 and PC2 for model 3 explained 65.8% of yield variation.
