Abstract: Ten lines were crossed in diallel fashion (10x10) and resultant 45 hybrids were evaluated in randomized block design with three replications in kharif 2018 at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut for fodder yield and its components for path analysis. Analysis of variance showed highly differed significantly for all the attributes namely, days to 50% flowering, plant height, leaf breadth, leaf length, leaf area, stem girth, leaves per plant, leaf stem ratio, total soluble solids and green fodder yield, which indicated that presence of great deal of diversity among the parents with respect to fodder yield and yield contributing traits. Genotypic and phenotypic coefficient of variation was high (more than 25%) observed for leaves per plant, leaf stem ratio and green fodder yield, which indicating that more variability and scope for selection in improving these characters. High heritability accompanied with high genetic advance as percent of mean was noted for plant height, leaf area, stem girth, leaves per plant, leaf stem ratio, total soluble solids and green fodder yield per plant. This indicated that these traits were highly heritable and selection of high performing genotypes is possible to improve these attributes. Green fodder yield exhibited significant stable and positive correlation with stem girth, leaves per plant and leaf stem ratio at genotypic and phenotypic level. These characters may be considered as important yield component in forage sorghum. Leaf breadth displayed high order of direct effect on green fodder yield per plant followed by leaf area, plant height and leaves per plant at phenotypic and genotypic level, 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.
