The correlation studies in thirty four genotypes of brinjal comprising ten parents, twenty one F1 hybrids and three checks during summer season of 2014 indicated strong positive correlation of primary branches per plant, days to final harvest, flowers per cluster, fruits per cluster, fruit length, average fruit weight and fruits per plant with fruit yield per. However, a significant negative correlation of fruit yield per plant was observed with days to 50% flowering. The path analysis study revealed that the fruits length is the most important yield determinant, because of its high direct effect and indirectly influence the yield through primary branches per plant, days to final harvest, fruits per cluster, average fruit weight and fruits per plant followed by fruits per plant is the another most important yield determinant thus, these characters should be given importance in selection programme for yield improvement in brinjal.
