Genetic variability analysis and heritability of different yield contributing characters were investigated in 44 mulberry genotypes for six morphological and eight physiological traits to understand the available genetic variability for future improvement of mulberry. Phenotypic coefficient of variation (PCV %) was found to be higher than the respective genotypic coefficient of variation (GCV %) for all the characters denoting variability among genotypes. Estimates of phenotypic and genotypic coefficient of variation were high for fresh leaf weight (39.72, 35.06%) moderate for other traits (10-30%) and least in moisture percentage (9.24, 6.81% respectively). High genetic advance coupled with heritability was observed in the characters namely, fresh leaf weight (77.9 %), followed by number of leaves per meter twig (68.6%), internodal distance (64.4%), leaf length (61.4%), dry leaf weight, moisture percentage (54.3%) and actual leaf area (48.2%) and least in leaf width (36.7%). High genetic advance coupled with high heritability revealed significant contribution of fresh leaf weight among studied components. The study revealed importance of agro-morphological traits in characterization of germplasm accessions and in selection for future breeding programmes.
