Online published on 25 July, 2018. Abstract Genetic analysis was performed on progenies developed in F2 generation of an inter-varietal cross Arka Keshav x Bhola Nath of brinjal, Solanum melongena L using North Carolina Design-1. The experiment was conducted during Kharif (April-November) 2012 and 2013 in randomized block design (RBD) with three replications at experimental farm of Department of Vegetable Science and Floriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. Biparental progenies were superior in mean performance than were F3s. Dominance variances were greater than additive variance for most characters. For fruit diameter, plant height, branches per plant and total soluble solids additive component of genetic variance was of higher magnitude. The average degree of dominance was in over-dominance range for most traits. Plant height, number of branches per plant, fruit diameter and total soluble solids were in the partial dominance range. Heritability estimates were generally low to medium. Fruit weight exhibited moderate to high heritability. The pre-ponderance of additive and non-additive genetic components of variance for most traits indicated role for additive and non-additive gene action for inheritance of marketable fruit yield and its component traits. These could be utilized through recurrent selection and heterosis breeding for the development of high yielding and quality cultivars in eggplant.
