Mean: average over adjusted means for hybrid (Hyb)- and population (Pop)-type varieties. Upper value: Pooled phenotypic correlation coefficient ρp after eliminating-type means. Lower value: Genetic correlation coefficient ρ g. Categorization: 0.25 ≤|ρ| < 0.45 weak, 0.45 ≤ |ρ| < 0.65 moderate, 0.65 ≤ |ρ| < 0.85 strong, 0.85 ≤ |ρ| very strong
