The investigation on “Phenotypic evaluation and genetic variability studies in brinjal (Solanum melongena L.)” was undertaken during kharif season of 2017. Sixty brinjal genotypes were evaluated in randomized block design with two replications in vegetable science block, Dept. of Vegetable Science, Kittut Rani Channamma College of Horticulture, Arabhavi under the University of Horticultural Sciences, Bagalkot. In the study, analysis of variance revealed highly significant differences among genotypes for most of characters studied. The growth parameters viz., high phenotypic coefficient of variation (>20%) with moderate genotypic coefficient of variation (11-20%) was noticed in plant height at 90 DAT, number of primary branches per plant at 90 DAT, stem girth at 90 DAT and leaf area. Fruit weight, number of fruits per cluster and fruit girth had reported moderate phenotypic coefficient of variation (>20%) with genotypic coefficient of variation, while number of fruits per plant, fruit length, fruit yield per plant and phenols showed high phenotypic coefficient of variation with genotypic coefficient of variation. Phenols showed high phenotypic coefficient of variation with genotypic coefficient of variation (>20%) depicting the additive component is predominant. High heritability (>60%) estimates along with high GAM (>20%) was also noted in phenols. Plant height was found maximum in Acc-113 (64.90 cm), primary branches per plant 3.10 (Acc-65) to 7.00 (Pusa Shyamala), Minimum number of days to fifty % flowering (55.00) was observed in HUB – 23, IC 354597 recorded minimum fruit weight (73.00 g) while, maximum in Acc - 597 (174.30 g). HUB -13 recorded maximum number of fruits per plant (21.60) while, CO-2 with minimum number of fruits (7.40). Maximum fruit yield per plant was noted 2.67 kg in HUB – 13. Among the genotypes studied, phenols ranged from 75.98 (IC 354597) to 267.60 (Pusa Shymala). These results indicated the existence of sufficient variability in genetic stock studied and the environmental role is negligible. Hence, there is ample scope for improving these characters with direct selection in further breeding programme.
