Correlation of Rooting and Other Traits in Mulberry

Simple correlation co-efficients amongst six metric traits of nine different mulberry genotype groups were worked out. The extent of correlation varied from one-group to the other. Most of the correlations were straight forward, such as number of shoot/plant showing relationship with length of shoots, number of leaves/plant and leaf yield/plant. Interestingly there was a moderate and positive correlation between the length of shoots and the rooting in all the genotype groups except easy rooter group and the relationship was significant in pooled, medium sprouter, late sprouter, late sprouter and moderate rooter genotype groups. Further, a positive and moderate correlation of rooting was observed to exhibit with number of leaves and the leaf yield in all the genotype groups excepting the three rooter groups (poor, moderate, easy) where the association was very much feeble and insignificant.
