The study was conducted using 12 brinjal genotypes including two checks on three different locations in temperate zone of Kashmir region. The locations include Vegetable Experimental Farm, Division of Vegetable Science, SKUAST-Kashmir, Shalimar (E1); Krishi Vigyan Kendra, Kupwara SKUAST Kashmir (E2); Krishi Vigyan Kendra Bandipora SKUAST Kashmir (E3). To evaluate the yield and quality of the brinjal genotypes at all the three locations with an objective to study the genetic variability and genotypic correlation coefficient analysis. The experiment was laid out in complete randomized block design with three replications at each location. Observation was recorded on days to first flowering, plant height (cm), plant spread (cm), number of branches per plant, fruit length (cm), fruit diameter (cm), pedicel length (cm), average fruit weight (g), number of fruits per plant, yield per plant (kg), yield per hectare (q), TSS (oBrix), vitamin-C (mg per 100g), total phenol (mg per 100g), anthocyanin (mg per 100g), dry matter content %, seed vigour, seed index, seed yield per hectare (q). The mean performance of genotypes showed wide variation in individual as well as over the environments for all the traits under study. The analysis of variance for individual as well as over environments revealed highly significant differences among genotypes for all the characters under study indicating large amount of variability in the genotypes suggesting that there is an ample scope for improvement. Mean squares due to environments were significant for all traits except total phenol, anthocyanin and dry matter content suggesting the presence of diverse environments. For most of the traits under study, wide range of variability was observed thus depicting much scope for improvement through selection. Highest genotypic coefficients of variation were recorded in all the traits except for days to first flowering, plant height and dry matter content which indicates the higher magnitude of variability that can be utilized in future breeding programmes. Heritability in broad sense was high for most of the traits suggesting that the selection based on phenotype would be effective in these traits. Yield per plant (kg) exhibited significant positive correlation with seed yield per hectare(q), plant height (cm), number of fruits per plant, vitamin-C (mg per 100g), total phenol(mg per 100g).
