“…In accordance to the findings of Dharme Gowda (1977) and Iqubal et al (1995) the analysis of variance of combining ability for plant height in the F 1 generation showed significant additive and non-additive gene effect, with prevailing influences additive effect (Damnjanovic et al, 2002). Nonadditive gene action was predominant in the F 1 for plant height, while additive gene action was important for number of branches per plant .…”

“…The mean degree of dominance indicated over-dominance for all traits, except fruit weight. Dominant and recessive alleles were symmetrically distributed among the parents for yield / plant and fruit weight, while were not symmetrical in the parents as indicated by the ratio H 2 /4 H 1 , which was lower than 0.25 for fruit weight trait (Damnjanovic et al, 2002).…”

“…High heritability values were recorded for plant height and branch number per plant by Mehrotra and Dixit (1973), Borikar et al (1981), Kalda et al (1988) and Vadivel and Bapu (1989), for fruit number per plant by Hiremath and Gururaja (1974), Dharme Gowda et al(1979), Salehuzzaman and Alam (1983), Kalda et al (1988), Damnjanovic et al (2002) and Mahaveer et al (2004) and for average fruit weight and fruit yield per plant by Gill et al (1976), Chung et al (2003) and Omkar and Kumar (2005). In addition high heritability accompanied by high estimates of genetic advance (Mehrotra and Dixit, 1973;Bhutani et al, 1977;andKalda et al, 1988) Chaudhary (1999) found both combining and component analysis showed presence of additive and non-additive gene effects with preponderance of latter.…”

Five parents of eggplant were crossed in a diallel cross and evaluated in 2008 to study genetic components for some eggplant traits; i.e., plant height, branch number /plant, early fruit number, fruit weight / fruit in early yield, early yield / plant, total fruit number, fruit weight / fruit in total yield and total yield / plant.The results reflected insignificant t 2 for all the studied traits, except early yield/plant which t 2 was significant. By inspection, t 2 was found insignificant after removing P 4 . For all the studied traits, the estimates of D, H 1 and H 2 were significant for all these traits.Asymmetrical gene distribution was observed, except total yield which had symmetrical gene distribution (0.25). For total yield, complete dominance was found to control this trait, and the dominance is isodirectional.

Evaluation and prediction of the performance of hybrids is important in eggplant (Solanum melongena) breeding. A set of 10 morphologically highly diverse eggplant parents, including nine inbred S. melongena and one weedy S. insanum accessions, were intercrossed according to a half-diallel mating design without reciprocals to obtain 45 hybrids. Parents and hybrids were evaluated for 14 morphological and agronomic conventional descriptors and 14 fruit morphometric traits using Tomato Analyzer. Genetic distances among parents were estimated with 7,335 polymorphic SNP markers. Wide ranges of variation and significant differences were observed in the set of 55 genotypes for all traits, although the hybrids group had significantly higher vigour and yield than parents. General and specific combining abilities (GCA and SCA) were significant for most (GCA) or all (SCA) traits, although a wide variation was obtained for GCA/SCA ratios. Many relevant traits associated to vigour and yield had low GCA/SCA ratios and narrow-sense heritability (h2) values, while the reverse occurred for most fruit shape descriptors. Broad-sense heritability (H2) values were generally high, irrespective of GCA/SCA ratios. Significant correlations were found between traits related to size of leaf, flower and fruit, as well as among many fruit morphometric traits. Genetic distances (GD) among parents were coherent with their phylogenetic relationships, but few significant and generally low correlations were found between GD and hybrid means, heterosis or SCA. The results provide relevant information for developing appropriate strategies for parent selection and hybrid development in eggplant and suggest that GD among parents have limited value to predict hybrid performance in this crop.

Eleven morphologically diverse cultivated eggplant accessions were used for hybridization following half diallel mating design to obtain 55 hybrids. Evaluation of hybrids along with the parents was conducted over two locations followed by randomised complete block design with three replications to study gene action and combining ability of 15 morphological and biochemical traits. The analysis of variance indicated highly significant differences among the environments and interaction of genotype and environment, except for fruit length to width ratio. Additive gene effects were significant for the inheritance of these traits and expression of these additive genes were greatly affected by environments. The general combining ability (GCA) was greater than their respective specific combining ability (SCA) for all traits except for fruit yield per plant. High values of GCA and SCA effects for characters of interest were dispersed among different genotypes. From this study it was observed that the best parental line was BT15 based on days to first flowering, total number of fruits per plant, total soluble solids and total phenol content. Besides, the parent BM5 showed good general combining ability effects for fruit yield per plant, fruit length and fruit length to width ratio and the parent BB1 performed good general combining ability for fruit diameter, fruit girth and fruit weight. Besides, other parents showed the best performance for only one trait. On the other hand, the hybrid BT6 × BT15 was reported bearing early flowering with high total phenol content and the hybrid BM9 × BB26 has high fruit yield with high soluble solids. Besides, the hybrid BM9 × BB1 has a high fruit diameter and fruit weight. All other hybrids except for these three (BT6 × BT15, BM9 × BB26 and BM9 × BB1) were shown the best performance for only one trait. Hence, based on the desired trait, the hybrid can be selected for future use after large scale evaluation.
