An experiment was conducted on rabi 2012-13 for evaluation of 35 genotypes of brinjal for 21 characters revealed that PCV was greater than corresponding GCV for all traits. Maximum PCV (56.26%) and GCV (55.68%) were registered for fruit length: diameter ratio. High estimate of heritability coupled with high genetic advance for most of the yield and its contributing characters which indicating phenotypic selection would be effective for the genetic improvement in these traits. Fruit yield displayed highly significant and positive correlation with number of flowers per cluster (0.49), number of flowers per plant (0.61), number of fruits per cluster (0.41), number of fruits per plant (0.72) and number of branches per plant (0.48) at genotypic level. Path co-efficient study indicated the highest positive direct effect of fruit length : diameter ratio (2.4326) on fruit yield per plant followed by number of fruits per plant (1.2644), fruit diameter (1.2539), dry matter content of fruit (0.9633), moisture content of fruit (0.9238)and number of flowers per cluster (0.9098).
