Abstract:

Genetic variability is the pre-requisite for the initiation of any improvement programme for the identification and selection of superior entries over the existing cultivars. The investigation was conducted in 47 genotypes maintained at mulberry germplasm block at CSB-Central Sericultural Research and Training Institute (CSRandTI), Pampore for 13 agro-morphological traits to understand the available genetic variability for future improvement in mulberry. Analysis of variance (ANOVA) showed highly significant differences (P=0.01) between the genotypes for the agro-morphological traits studied. High level of phenotypic and genotypic coefficient of variation (>20%) observed for petiole length, petiole weight, leaf length, leaf width, number of leaf attached on main shoot, number of nodes on main shoot, total shoot length, leaf weight of main shoot, main shoot weight, total shoot weight per plant and total leaf weight or leaf yield indicated that these traits are governed by genetic factors. High heritability estimates coupled with high genetic advance as per cent of mean (GAM) for indicated additive gene action and improvement can be made through selection. Correlation coefficient association analysis revealed significant and positive correlation of leaf yield with yield components. The study revealed importance of direct selection for the improvement of agro-morphological traits.
