“…While, Rf8 was the best general combiner for plant height and seed oil content %. These results were in accordance with the findings of Azab et al(2014); Imran et al(2015); Memon et al(2015); Vikas et al(2017); Cvejic et al(2017); Biradar et al(2018), Bhoite et al(2018), Singh et al (2018), Telangre et al(2019), Haddadan et al (2020) and Rizwan et al, (2020) .…”

Seven sunflower cytoplasmic male sterile (CMS lines) and three Rf-restorer (tester lines) were used to obtain 21 F1 hybrids according to line x tester mating design. All the 21 F1 hybrids, 7 lines, and three testers were evaluated at Sakha Agricultural Research Station, Kafer El-Sheikh Governorate during 2017 season. The results showed highly significant differences among the genotypes for all the studied traits. The major role of dominant genes was found because the degree of dominance was greater than unity. These results indicated the preponderance of dominant gene action and the feasibility of hybrid sunflower development. A5 and A9 of CMS lines and RF1 of restorer lines proved to the best general combiners for head diameter, seed yield plant -1 and seed oil content. The cross combinations of A5 x Rf1 and A7 x Rf8 were identified as the best for seed yield per plant with highly significant SCA effects and heterosis. Combining ability analysis indicated that both genetic components, additive and non-additive, were important in expression of investigated traits. The components of genetic variance indicated that the non-additive component played the main role in the inheritance of all studied traits. Heritability in broad sense (h 2 b) was larger than that in narrow sense (h 2 n) for all studied traits.

Twenty four hybrids along with ten parents and four standard checks were evaluated in a Randomized block design with two replications at Regional Agricultural Research Station, Nandyal during rabi, 2018-19. The analysis exhibited significant differences among lines for ten traits and testers for nine traits. The lines x tester interactions were significant for eleven traits. The mean squares with respect to crosses were significant for all the characters except stem girth. The GCA and SCA variances revealed existence of non-additive gene action for most of the traits. The parental line CMS 30 A was a good general combiner as it possessed significantly high GCA effects for most of the economic traits like leaf area index, plant height, head diameter, number of leaves per plant, days to maturity, 100 seed weight, autogamy per cent, seed yield, hull content, oil content and oil yield, while NDLA-4 was a good general combiner for specific leaf area, number of leaves per plant, number of seeds per head and volume weight. The tester NGM-16 was a good general combiner for seed yield and yield component traits. The crosses NDLA-3x NO-30, CMS-30 A x R-106 and NDLA-4 x NGM-16 were promising hybrid combinations for seed yield with regard to specific combining ability (SCA) effects and these hybrids could be tested in multi location trials further if they have exploitable level of commercial heterosis .
