Correlation studies in mulberry (Morus spp.)

Correlation coefficients and path coeffiCients were calculated for leaf yield and its twelve components from 23 genotypes comprising 8 parental and 15 selected F₁ hybrids in mulberry (Morus spp.). Leaf yield is found to have higher positive correlation with laminar index (w.t.), weight of 100 dry leaves, number of branches per plant, internodal distance, annual aerial biomass, stem weight, number of leaves per branch and secondary branches per plant. Path analysis revealed that internodal distance, annual aerial biomass, stem weight, number of leaves per branch, number of primary branches had strong direct effect on leaf yield.
