Abstract:
The present experiment on genetic variability and correlation in brinjal was carried out with 38 locally collected genotypes with the objective to improve the yield through selection. The results revealed that wide variability was found for different traits in brinjal. Invariably, higher values were observed for phenotypic coefficient of variation with respect to corresponding genotypic coefficient of variation indicating the impact of environmental factors towards trait expression. High estimates of genotypic co-efficient of variation, heritability (broad sense) and genetic advance as percentage of mean together at a glance were observed for the characters such as fruit yield per plant, number of fruits per plant, fruit weight, fruit girth and node at which first flowering appeared, suggesting additive gene action for expression of these characters indicated their possibility of improvement with simple selection procedure in Brinjal. Similarly, correlation studies among the traits indicated that there is a strong inherent association between yield per plant with characters like plant height and number of fruits per plant. Further, plant height, number of fruits per plant, fruit weight, fruit girth, days to 50% flowering, days to first fruiting and days to edible maturity showing significant positive association both at genotypic and phenotypic levels suggested that, these are important correlated characters contributing towards fruit yield of brinjal and simultaneous improvement in these characters will be helpful in brinjal improvement programme.
