Abstract
The present investigation was carried out to assess the genetic variability in thirty advanced breeding lines of brinjal at College of Horticulture, Mudigere during Rabi 2021- 2022. The The experiment was laid out in randomized complete block design with three replications. Significant differences were observed among genotypes for all the characters under study. High heritability (> 60 %) coupled with high genetic advance (> 20 %) as per cent over mean was observed for plant height and number of primary branches at 30, 60 and 90 DAT, days to first flowering, number of flowers per cluster, number of fruits per cluster, days taken to first picking, number of fruits per plant, average fruit weight, fruit length, fruit diameter, fruit yield per plant, dry matter content and fruit phenol content indicating that these characters are governed by additive gene action. Hence, direct selection can be followed for improvement of these characters. Correlation studies revealed that fruit yield per plant exhibited highly significant and positive association with number of fruits per plant, plant height at 60 DAT, fruit setting percentage, plant height at 90 DAT, number of primary branches at 60 DAT, number of fruits per cluster, number of primary branches at 90 DAT and fruit diameter. Path analysis revealed that fruit yield per plant had direct positive effect on number of fruits per plant, average fruit weight, plant height at 60 and 90 DAT, number of fruits per cluster and fruit diameter. Based on the mean performance, the lines CHMB 2, CHMB • 17, CHMB 6, CHMB 18, CHMB 4, CHMB 9, CHMB 29, 23 were found superior and these lines can be utilized CHMB 20, CHMB - 24 and CHMB 8 for further improvement of brinjal crop.
