Grain yield was found to have significant and positive phenotypic correlations with all the characters except days to maturity and 250-grain weight where the correlations were non-significant but positive. Yield was found negatively correlated at genotypic level with plant height, leaf area, ear length and grains/ear. The path analysis at phenotypic level indicated that plant height, tillers/plant, grains/ear and 250-grain weight, were the important yield contributing characters. Days to maturity, grains/ear and leaf area only contribute positively and directly to the grain yield at genotypic level.
