Evaluation of brinjal genotype under hot arid agro-climate

Abstract

The present investigation was carried out under hot arid agro-climatic conditions to study the genetic variability, heritability, expected genetic advance and character association for nine traits in brinjal. The experimental material comprised of 20 genotypes of brinjal. The genotypes V18, V14 and V3 were superior based on mean for fruit yield per plant. Wider variability was observed for plant height, number of primary branches per plant, leaf length, leaf width, fruit length, fruit width, number of fruits per plant, average fruit weight and fruit yield per plant. PCV was in general higher than the GCV and the highest genotypic coefficient of variation was recorded for fruit yield per plant followed by average fruit weight and number of fruits per plant. All these characters also recorded high heritability and genetic advance which indicates participation of additive genetic variance. Correlation coefficient analysis revealed that fruit length, fruit width, number of fruits per plant and average fruit weight had the significant positive correlation with fruit yield per plant. Hence selection will be effective for these traits.
