| dc.description.abstract | A field experiment was carried out with a view to estimate heterosis and combining ability and gene effects in brinjal (Solanum melongena L.). The experimental material comprised of 8 parents, 28 hybrids and one standard check (Surati Ravaiya) and 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 2014-15 (crossing programme) and Rabi 2015-16 (evaluation programme). The data were obtained for ten characters including fruit yield and its components. Significant differences were observed among parents and hybrids, indicating considerable genetic variation among genotypes. The crosses viz., AB-09-1 × AB-12-10, AB-09-1 × AB-08-5, AB-08-5 × JBL-08-8, GJB-3 × AB-12-10, JBGR-1 × NSR-1, NSR-1 × AB-12-10 and AB-09-1 × NSRP-1 showed significant and desirable heterosis for fruit yield per plant over standard check. Where as crosses viz., AB-09-1 × NSR-1, ii AB-09-1 × AB-12-10, NSRP-1 × NSR-1, JBGR-1 × NSR-1, JBGR-1 × JBL-08-8 and GJB-3 × JBL-08-8 showed significant and positive heterobeltiosis for fruit yield per plant. 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 days to fifty per cent flowering, plant height at harvest, number of branches per plant at harvest, fruit length, average fruit weight, number of fruit per plant and total soluble solids indicated preponderance of non-additive gene action. While, magnitude of variance due to GCA were comparatively larger than those of SCA for fruit diameter, fruit yield per plant and total phenol content indicated preponderance of additive component of genetic variance. Among the parents, viz., JBGR-1, NSR-1 and JBL08-8 were found good general combiners for majority of the characters. Hybrids viz., AB-09-1 × AB-12-10, AB-09-1 × AB08-5, AB-08-5 × JBL-08-8, GJB-3 × AB-12-10, JBGR-1 × NSR-1, NSR-1 × AB-12-10 and AB-09-1 × NSRP-1 showed higher order sca effects for fruit yield and its component characters. In the present investigation, entitled ―Breeding investigations in brinjal (Solanum melongena L.)‖ the crosses viz., AB-09-1 × AB-08-5, AB-09-1 × NSRP-1, AB-09-1 × JBGR-1, AB-09-1 × GJB-3, AB-09-1 × AB-12-10, JBGR-1 × GJB-3, JBGR-1 × JBL-08-8, NSR-1 × GJB-3, NSR-1 × JBL08-8, GJB-3 × JBL-08-8, and GJB-3 × AB-12-10 as well as parent AB-09-1 recorded the lowest shoot and fruit borer iii infestation. All the parents (except JBGR-1) and all the crosses (except AB-09-1 × GJB-3, AB-08-5 × GJB-3, NSRP-1 × GJB-3, JBGR-1 × GJB-3 and NSR-1 × GJB-3) recorded the least bacterial wilt infection in field condition. | en_US |
