Combining ability studies in Brinjal

Abstract

The experimental material comprised of 56 genotypes including 10 parents, 45 hybrids and one standard check (GHB-1) was laid out in randomized block design with three replications at Vegetable Research Station, Junagadh Agricultural University, Junagadh during Rabi 2016-17 (E1), Late kharif 2017-18 (E2) and Rabi 2017-18 (E3) to estimate, combining ability and gene effects in brinjal (Solanum melongena L.). Combining ability analysis revealed that both additive as well as non-additive variances were important in the inheritance of all the traits studied. However, magnitude of variances due to sca was comparatively larger than those of gca for most of the economic traits indicated preponderance of non-additive gene action. Among the parents, PLR 1, GJB-3, JBL-08-08 and JB-12-06 were good general combiners for fruit yield per plant. The crosses viz., AB-09-1 × AB-12-10, AB-09-1 × AB-08-5, AB-08-5 × JBL-08-8 and GJB-3 × AB-12-10 showed significant and positive sca effects in addition to desirable performance for fruit yield and its component characters.
