Genotypic correlations were of higher magnitude as compared to their corresponding phenotypic correlations for most of the character combinations. Green fodder yield was found to be positive and significantly correlated with green fodder yield per day, days to 50% flowering, days to milking stage, leaf length, nodes per plant and plant height. This indicates that any selection based on these characters will enhance performance and improvement in forage sorghum. Path coefficient analysis showed that green fodder yield per day, days to milking stage and days to 50% flowering were the most important characters controlling directly green fodder yield. High indirect positive contribution of days to milking stage and green fodder yield per day mainly via days to 50% flowering, leaves per plant and plant height mainly via days to milking stage and green fodder yield per day mainly via leaf length. This indicates that, effectiveness of selection for high fodder yield could be enhanced by inclusion of green fodder yield per day as a selection criterion along with the days to milking stage.
