Abstract: Present investigation was carried out during Kharif season at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The analysis of variance revealed highly significant variance for all the nine traits viz., days to 50% flowering, plant height, number of leaves per plant, stem girth, leaf length, leaf breadth, total soluble solids, leaf area and green fodder yield depicting greater variability in the existing material. Genotypic and phenotypic coefficient of variation were found high (more than 25%) for plant height, stem girth and green fodder yield, which indicating that more variability and scope for selection in improving these characters. High heritability coupled with high genetic advance were exhibited for plant height, leaf area, stem girth and green fodder yield, which indicates that preponderance of additive gene effects for these attributes and hence may prove useful for effective selection. Correlation coefficient studies indicated that phenotypic correlation coefficient was found to be higher than genotypic correlation coefficients for all the characters which, indicates phenotypic expression of the association were influenced by the environmental factors among the various traits. Green fodder yield recorded significant and strong positive correlation with leaf area followed by stem girth, plant height, leaf length and number of leaves per plant at both genotypic and phenotypic level. Therefore, these attributes is useful to the breeders in selecting suitable plant type. Path coefficient analysis showed high positive and direct which indicated that the contribution of individual attributes to fodder yield is of importance in planning a sound breeding programme for developing for high yielding varieties.
