Correlation coefficient analysis assess the mutual relationship between two plant characters and establishes the yield components upon which selection is to be done for improvement in yield. From the present study, yield per plant exhibited high significant and positive association with fruit length, fruit width, average fruit weight and total phenol content. These characters should form selection criterion in breeding programmes. Direct selection based on these traits could result in simultaneous improvement of traits and fruit yield in brinjal. It was also observed that genotypic correlations were high as compared to their phenotypic correlations revealing strong inherent association between these characters. Path coefficient analysis revealed the direct and indirect effects of various components characters on yield. Thus, characters viz. days to 50 percent flowering, number of flower clusters per plant, number of flowers per cluster, number of fruits per plant, days to first harvest, average fruit weight, days to last harvest, fruit length, fruit width, average fruit weight and total phenol content showed positive correlation and positive direct effect on fruit yield per plant.

The study revealed significant differences among all studied traits. Highly significant differences were observed among all the genotypes and characters under study indicating the presence of sufficient amount of variability in all the characters. PCV estimates were higher than their corresponding GCV for all characters studied. PCV and GCV were high for fruit weight (26.2,22.2%), fruit length (22.7, 20.8%), no. of fruit per cluster (21.3, 17.1%), fruit yield per plant (20.7, 18.9%),shoot and fruit borer infestation (18.4, 16.1%), total phenol content (18.3, 13.1%), whereas, plant height, no. of branches per plant, days to first flowering, days to 50 percent flowering, no. of flower cluster per plant, no. of flower per cluster, no. of fruits per plant, days to first harvest, days to last harvest and ascorbic...
