摘要

Genotypic correlation coefficients provide a measure of the genetic association among characters and give an indication of characters that could be useful so as to identify more important ones for a particular selection programme. Correlation studieswere conducted to study the degree of interrelationship between forage yield, grain yield and their major contributing traits. Most important trait viz: green fodder yield plant~(-1) exhibited a significant positive genotypic correlation with number of leaves plant~(-1), number of tillers m~(-1) row, plant height (cm), culm diameter (cm), leaf stem ratio, dry fodder yield plant~(-1) (g) and negatively significant correlation with crude protein content % and ADF%. Days to 50% flowering had negative significant association with Green fodder yield plant~(-1) and leaf stem ratio. Number of leaves plant~(-1) had a significant positive correlation with culm diameter, number of tillers m~(-1), plant height and leaf stem ratio. Plant height had a significant positive correlation with leaf stem ratio, culm diameter and number of tillers m~(-1). Crude protein content and acid detergent fibre showed significant negative association with green fodder yield which suggested that these traits cannot be simultaneously improved. Grain yield plant~(-1) exhibited significant and positive correlation coefficients with spike-lets panicle~(-1), 1000 seed weight (g) and seed length breadth ratio but negative non significant correlation with protein content. These results will be beneficial in devising a selection scheme for identifying best genotypes possessing higher forage yield, grain yield and better quality.
