Abstract:
Character association and path analysis was studied in thirty five genotypically diverse indigenous genotypes of brinjal at Sri Konda Laxman Telangana State Horticultural University during the Rabi, 2017-18. 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 co-efficient 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.
