“…Whereas, two hybrids viz., AKS CMS-2A × AKS-1731 and AKS CMS-3A × GMU-7448 were significantly superior for the traits seed volume weight and the number of capsules per plant. A similar result has also been reported earlier by Ahmad et al (2016) and Thorat and Gawande (2021) for both traits in safflower. A hybrid AKS CMS-2A × AKS-6891 followed by AKS CMS-3A × GMU-2273 exhibited good sca effects for the trait seed yield per plant in a desirable direction.…”

Combining ability analysis discriminates the parents and crosses, provides information about the breeding method to be adopted for genetic improvement of a specific character. Thirty hybrids obtained by mating two females with fifteen males in L × T fashion were evaluated in RBD along with parents to estimate the combining ability of parents and crosses for seed yield and yield contributing traits. The parents and hybrids significantly differed amongst themselves for different characters, viz., days to maturity, 100 seeds weight, capsules per plant, branches per plant, seed yield, seed volume weight and oil content. Among the males, GMU-590, GMU-2273, GMU-2830 and GMU-589 and the females, AKS CMS-3B had good gca effects for seed yield and some other yield contributing traits. However, GMU-7573 and GMU-2830 were found best general combiners for the trait oil content. All these selected parents may be utilised in a different breeding programme for genetic enhancement of the trait involved. The hybrids AKS CMS-2A × GMU-1731 and AKS CMS-3A × GMU-7448 were identified as good combinations for seed volume weight and capsules per plant. Whereas the hybrids AKS CMS-3A × GMU-2273 and AKS CMS-2A × GMU-6891 were effective for seed filling percentage and seed yield per plant. Three promising hybrids viz., AKS CMS-3A × GMU-7448, AKS CMS-3A × GMU-2273 and AKS CMS-2A × GMU-6891 were designated as promising hybrids as they had good per se performance and significant sca effects for seed yield per plant and most of its contributing characters which can be utilized for heterosis breeding and release of new hybrids at commercial level after thorough multilocation testing. Further, the hybrids AKS CMS-3A × GMU-7448, AKS CMS-3A × GMU-590 and AKS CMS-3A × AKS-589 involving one or both good general combining parents with non-significant sca effects for many studied characters which may be utilized to isolate desirable segregants in progressive generations for identification and release of new varieties by hybridizing the 'B' lines of concerned CMS line with similar males again.

“…The general combining ability of the all parents in terms of head number, head diameter, number of seeds per head and 1000 seed weight were insignificant statistically (Table 3a). The present results confirm the findings of Golkar et al (2012), Kose (2017), Kanoje et al (2018) and Thorat and Gawande (2021). GCA effects of the parents in terms of the seed yield and quality traits were given in Table 3b.…”

“…Similar results were reported earlier by Kose (2017) and Kanoje et al (2018). In addition, Thorat and Gawande (2021) determined that the SCA values ranged from -2.145 to 2.145 in terms of oil content. It can be said that the reason for this difference is that the genotypes used belong to different geographical origins.…”

This research was conducted in 2018 and 2019 at Tekirdag Namık Kemal University, Faculty of Agriculture, Field Crops Department, Research and Experimental area. It was aimed to determine general combining abilities (GCA) of parental lines, specific combining abilities (SCA) of hybrids, having F1 hybrids from 5 female lines and 9 male testers. For this purpose, lines and testers were hybridized in all combinations using line x tester method in 2018. The field experiments for hybrids (F1) were designed in a randomized complete block with three replications in 2019. The male parents Linas as high general combiners for developing increased seed and oil yields in safflower hybrids. The highest heterosis for oil content was calculated EC18 hybrid (14.281%). The highest heterosis was calculated in EC2 (34.079%) and EC4 (34.548%) for seed and oil yield, respectively. In the study, similar heterotic effect was observed between seed and oil yield as there is interaction between them. Hybrid EC2, EC4 and EC18 were determined as best combinations for high seed yield, oil content and oil yield according to the SCA and heterosis values. The promising hybrids will be grown in the next generations together with the other hybrids in order to ensure sufficient variation, and the selection will be started in the later generations such as F3 and F4.

“…Different varieties of diallel crosses exist, however, in terms of the number of reciprocal crossings, half diallel crosses are more manageable for breeders than full diallel analysis 7 . Combining ability analysis is an effective tool for identifying superior hybrid parents with high general combining ability (GCA) and progenies with improved specific combining ability (SCA) 45 . It is also useful for measuring the genetic worth of parents and crossings in terms of gene activity in quantitative character inheritance and exploitation and breeding 13 .…”

Nine morphologically distinct kenaf genotypes were hybridized to produce 36 hybrids following a half diallel mating design. The combining ability and gene action of 15 yield and yield components were assessed in hybrids and their parents across two environments. Except for the mid diameter and plant height traits, there were highly significant differences (p ≤ 0.01) between the environments and the interaction of genotype and environment. Additive gene effects were considerable for the inheritance of these traits, and the expression of these additive genes was heavily influenced by the environment. Significant differences were found for all studied traits for GCA except top diameter and SCA except plant height and top diameter, implying the presence of both additive and non-additive gene action for the inheritance of the concerned characters. For all features except top diameter and number of nodes, the magnitude of GCA variation was significantly higher than that of SCA variance, indicating the additive gene's predominance. The parental lines P1, P3 and P4 were outstanding general combiners for fiber yield and yield-related parameters. Considering combining ability and genetic analysis study, the crosses P1 × P4, P1 × P9, P2 × P3, P2 × P5, P4 × P6, P4 × P7, P4 × P9, P5 × P8, and P7 × P9 were found promising for their heterotic response to higher fiber yield, stick yield, seed yield and could be for future improvement in kenaf breeding programmes.
