Abstract:
An assemblage of fifteen distinct eggplant genotypes underwent thorough evaluation to estimate the extent of genetic diversity, heritability, and genetic advancement across sixteen distinct attributes. The evaluation took place during the Rabi season of 2020-21 at the Vegetable Research Farm located within the Department of Horticulture at Banaras Hindu University's Institute of Agricultural Sciences in Varanasi. The outcomes derived from the analysis of variance clearly revealed notable genetic variations among the eggplant genotypes, implying a substantial level of diversity within these genotypes. This signifies considerable potential for improving relevant characteristics through selective breeding. Among all the observed traits, the phenotypic coefficient of variation (PCV) consistently exceeded the genetic coefficient of variation (GCV), albeit with minor differences. This suggests that the impact of environmental factors on the manifestation of these traits is comparatively limited. Particularly noteworthy were attributes such as the number of seeds per fruit, number of fruits per plant, fruit width, ascorbic acid content, fruit yield per plant, fruit yield per hectare, average fruit weight, fruit length, and test weight, all of which exhibited notable PCV and GCV values. In the case of attributes such as the number of seeds per fruit, number of fruits per plant, and ascorbic acid content, a combination of substantial heritability and significant genetic advancement was evident. This observation underscores the predominant influence of additive genes on these traits, suggesting their potential for effective enhancement through phenotypic selection.
