“…The parent with best general combining ability effect for number of immature seeds per fruit was G5. This is in accordance with the study carried by Vani et al [10], Arvind et al [11], Kalaiselvan and Anuja [12] and Rajani et al [13].…”

The present study on general combining ability effects and specific combining ability effects involves seven parents viz., G1 (Arka Anamika), G2 (Aruna), G3 (Varsha Uphar), G4 (Pusa-5), G5 (MDU-1), G6 (Kashi Kranti), G7 (Ankur-41) with their 21 F1 hybrids through half-diallel mating system. The present investigation was undertaken using Randomized Block Design with three replications. The combining ability effects were estimated for seven characters viz., days to first flowering, days to first fruit harvest, fruit length, fruit girth, fruit weight, number of immature seeds per fruit and fruit yield per plant. The results showed that gca effects of parents and sca effect of hybrids were significantly differed. The SCA variance was higher than the GCA variance that indicates the presence of preponderance of non-additive gene action for all the seven traits i.e., presence of preponderance of non-additive gene action for all characters except number of nodes per plant. Among the parents, G3 was found to be a good general combiner based on the per se performance and gca effects for its flowering and yield traits. Among the 21 F1 hybrids, the crosses G3 x G5 and G4 x G6 were superior on the basis of per se performance and sca effect for flowering and yield attributes. Hence, these hybrids were used for further exploitation of heterosis.

“…For other traits, hybrids showed non-significant positive or negative values for the effect of special combining ability, indicating trait reductions compared to the general mean. These results align with findings by [29][30][31][32][33][34]. As shown in Table 7, it's evident that the variance of special combining ability of hybrids ( SCA) exceeds the components of the variance of general combining ability ( GCA) for traits such as the number of nodes sets, percentage of pod sets, and plant yield.…”

The field experiment was carried out over the 2021 and 2022 growing seasons with the aim of locally developing a single hybrid from grown okra cultivars, and known general and specific combining abilities in one of the private fields in the Mahmoudiya district of Baghdad. In this experiment, ten okra cultivars (denoted as O1 to O10) were introduced into a hybridization program using a 7-line × 3-tester arrangement. Subsequently, in the second season, an experiment was conducted to evaluate the hybrids, their parental lines, and commercial hybrids, totaling [10 Parents + 21 Hybrids + Commercial Hybrid]. The experimental design employed a Randomized Complete Block Design (RCBD) with three replicates across randomized sectors. Growth Traits were studied. Hybrid vigor and stander+ heterosis were calculated, and genetic analysis was carried out. The results indicated that certain parents, specifically O1, O3, O4, O7, and O10, exhibited a positive and significant general combining ability effect in the measured traits, particularly. Notably, the hybrids O4×O2 and O10×O3 displayed a distinct positive and significant specific combining ability effect on pod weight and overall plant yield. Additionally, the dominance variance (σ2D) exceeded the additive variance (σ2A) across in traits (no. of nodes, no. of. leaves, percentage of pods, plant yield). The average degree of dominance (ā) was most pronounced in traits related to the number of pod sets on the main stem and the percentage of nodes set, as well as plant yield. The heritability broad sense was particularly high for phalanx length (92.75%), and plant yield (84.11%), while it was moderate for the number of nodes on the main stem and the percentage of pods. The hybrid O4×O2 also recorded the highest pod weight at 5.31 g and exhibited exceptional hybrid vigor and heterosis in pod weight traits (59.96% and 53.17%, respectively), as well as in plant yield (54% and 22.73%).
