Combining ability for yield and yield attributing characters in brinjal (Solanum melongena L.)
Abstract
A field experiment was carried out with a view to estimate, combining ability and gene effects in brinjal (Solanum melongena L.). The experimental material comprised of 37 genotypes including 8 parents, 28 hybrids and one standard check (Surati Ravaiya) was laid out in Randomized Block Design with three replications at Regional Horticultural Research Station (R.H.R.S.), Navsari Agricultural University, Navsari, Gujarat during Rabi 2015-16. Combining ability analysis revealed that both additive as well as non-additive gene effects were important in the inheritance of all the traits studied. However, magnitude of variances due to sca were comparatively larger than those of gca for most of the economic traits indicated preponderance of non-additive gene action. Among the parents, JBGR-1, NSR-1 and JBL-08-8 were good general combiners for majority of the traits. 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 higher order sca effects in addition to performance for fruit yield and its component characters.
