Genetic Variability Studies in Brinjal (Solanum melongena L.) for Quantitative and Qualitative Characters

A study was carried out on brinjal to estimate variability, heritability, and genetic advance in the Department of Vegetable Science, College of Horticulture and Forestry, Pasighat. The high Genotypic coefficient of variation (GCV) and Phenotypic coefficient of variation (PCV) (>20%) values for fruit diameter, fruit length, fruit weight, number of branches per plant, leaf area, number of fruits per plant, number of seeds per fruit, total phenol, anthocyanin, and solasodine content indicated high genetic variability among genotypes, making selection more effective for brinjal improvement. High heritability and high genetic advances were seen in the number of seeds per fruit, fruit yield per ha, leaf area, fruit weight, anthocyanin, and total phenol, which may be owing to additive gene action and selection from these traits being more successful.
