Abstract: Eggplant or brinjal Solanum melongena (L.) is the most popular and widely cultivated vegetable crop in the central, southern and Southeast Asia and in some African countries. In the present investigation 30 genotypes of brinjal were evaluated for genetic diversity and yield related traits with randomized block design (RBD) with three replications during Kharif 2017. Ten quantitative traits were considered to obtain information on the nature and magnitude of genetic variability, degree of association among different yield contributing traits with yield and related traits and the degree of genetic divergence and molecular analysis at morphological level. Observations were recorded on various characters viz. days of 50% flowering, plant height, number of primary branches per plant, plant spread, fruit length, fruit diameter, fruits per plant, average fruit weight, fruit index and yield per plant. Analysis of variance revealed substantial amount of variability among the genotypes for all the characters, under study, indicated wide spectrum of variability among the genotypes. High genotypic and phenotypic coefficient of variation was observed for fruit index (33.30, 34.40), moderate PCV and GCV was recorded for yield per plant (29.47, 29.88), average fruit weight (28.84, 28.94), fruit diameter (27.16, 27.89), fruits per plant (25.92, 26.59). High heritability coupled with high genetic advance was observed for average fruit weight (99.36, 59.23), yield per plant (97.27, 59.87), plant spread (95.94, 30.35), fruits per plant (95.01, 52.04). Moderate heritability was recorded for fruit diameter (94.84, 54.50), fruit length (94.68, 50.26), fruit index (93.74, 66.43).
