SUMMARY
The present study was carried to know the variability parameters and character association in single cut sorghum varieties under the arid and semi arid condition of Gujarat. Genotypic coefficient of variation (GCV) was maximum for green fodder yield followed by dry fodder yield and their per day productivity. High heritability coupled with high genetic advance and high GCV was observed for green fodder yield followed by dry fodder yield and their per day productivity, leaf breadth and plant height. The green fodder yield showed positive and significantcorrelation with dry fodder yield, green and dry fodder yield per day, number of leaves per plant, plant height, leaf length and stem girth. It was also observed that characters that exhibited positive associations with fodder yield have also showed positive associations among them selves. The characters like green and dry fodder yield per day and number of leaves per plant were exerted positive directeffectson green fodder yield. Where as the plant height, leaf length and stem girth showed negative direct effect with green fodder yield, which may be a result of the indirect effect of these traits via other traits.
Key words: variability, character association, path analysis, single cut sorghum
