Abstract:
The present investigation was carried out with 70 F2 crosses of forage sorghum in completely randomized block design with 3 replications at GBPUAT, Pantnagar under normal sown condition. The observations were recorded on nine yield contributing traits and three quality traits. The statistical analysis for genetic variability was done using ANOVA, h2, GCV, PCV and GA. The analysis of variance revealed significant difference among the crosses with respect to different yield and quality traits. The results of the present study indicated that high heritability values were observed in plant height, leaf width, leaf area, stem girth, total soluble solids, leaf:stem ratio, green fodder yield, and dry fodder yield whereas low and moderate for other characters. High PCV values were observed for total soluble solids, leaf:stem ratio, and HCN content whereas low and moderate for other characters. High GCV value was observed for none of the any character whereas low and moderate for other characters. The high genetic advance as percent of mean was observed in leaf area, total soluble solids, leaf:stem ratio, HCN content, and green fodder yield whereas low and moderate for others.
