Abstract:

Understanding the genetic variability and diversity of a crops species provides opportunity for plant breeders to develop new and improved cultivars having both farmer-preferred and breeder-preferred traits. In the present study 11 morphological characters and 16 quantitative characters were recorded from 27 advance breeding lines/varieties to identify useful alleles for future breeding. Genotypes varied considerably in plant growth and morphological characters. The overall mean of Shannon-Wiener diversity index (H’) value was 0.733 with predominant traits that exhibited wider variations were fruit colour, fruit curvature, fruit shape and growth habit, confirmed the existence of diversity among the genotypes.  The genotypes BCB-40, Bidhan Super, Garia exhibited high marketable yield, and fruits of SM-6-6, Arka Nidhi, 13/BRBW RES-3 were least infested by borer attack.  The genetic differences among these genotypes are potentially relevant to breeding programmes in that the variability created through hybridization of the contrasting forms could be exploited to get desirable recombinant in future.. High, genotypic coefficient of variation, heritability coupled with genetic advance for primary branches per plant, fruit length, fruit diameter, fruits per plant, fruit weight, marketable fruit yield per plant, anthocyanin content of peel, total sugar, reducing sugar, non-reducing sugar contents of fruit, shoot infestation by borer and fruit infestation by borer indicated that these traits are predominantly governed by additive gene action, so early generation selection would be helpful for improving these traits. Number of fruits per plant and fruit weight should be considered as the most important selection indices for enhancing marketable fruit yield in brinjal.
