Correlation coefficients and path coefficients were calculated for leaf yield and its 12 components from data on 23 genotypes comprising 8 parental and 15 selected F1 hybrids of mulberry (Morus alba), grown in West Bengal during 1992-94. Leaf yieldhad a high positive correlation with laminar index, 100-dry leaf weight, number of branches/plant, internodal distance, annual aerial biomass, stem weight, number of leaves/branch and secondary branches/plant. Path analysis revealed that internodal distance, annual aerial biomass, stem weight, number of leaves/branch and number of primary branches had strong direct effects on leaf yield.
