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 55 genotypes were collected and evaluated at the Research Farm of Department of Biotechnology and Crop Improvement during Khari season of 2015 to assess the mean performance, genetic variability, heritability and genetic advance. The experiment was laid out in Completely Randomized Block Design (RCBD) with 2 replications. ANOVA was found significant for all the traits .The mean performance for yield contributing traits, the genotype CBB-54 (11.80) showed highest number of flowers per branches and lowest CBB-16 (2.50), for number of fruits per plant the genotype A2 (53.00) highest and lowest by the genotype CBB-37 (8.75) , the average fruit weight recorded highest CBB-22 (176.70g) and lowest A13 (18.00g) and the fruit yield per plant showed maximum mean performance by the genotype A14 (2.90kg) and minimum by the genotype A12 (0.65kg). The mean performance for quality traits like, total phenol observed lowest for the genotype CBB-44 (0.54) and height CBB-50 (2.35), for reducing sugar the genotype A12 (0.31) highest and lowest by the genotype CBB-34 (1.38) and for ascorbic acid the highest recorded by the genotype CBB-49 and CBB-50 (18.50) and lowest by A13 (4.00). Estimates of phenotypic coefficients of variability (PCV) and genotypic coefficients of variability (GCV) ranged for average fruit weight (18.00- 176.70) followed by plant spread (51.70-87.60) respectively. PCV were slightly higher than the corresponding GCV and the difference was very low for majority of the characters, suggesting that prevalence of more of genetic effects than environment in their expression. Heritability in broad sense (h2), genetic advance (GA) and genetic advance as percentage of mean (GAM) ranged between 19-79-100%, 0.55-70.63, 23.17- 104.14 % respectively. High GCV, PCV, heritability coupled with High genetic advance indicating more of genetic inheritance and selection is effective. Therefore direct selection helps in selecting good genotypes with high growth, yield and quality for brinjal hybrids.
