“…The hybrid (A15 x Rf8) exhibited maximum positive heterotic effect (3.25%), along with 40.18 mean seed oil percentage. Similar results were obtained by Tan (2010), Hladni et al (2011), Azab et al (2014, Encheva et al (2015), Ingle et al (2015), Cvejic et al(2017), Vikas et al (2017), Bhoite et al (2018) Abd ElHadi et al(2019, Khan et al (2019), andHaddadan et al (2020) .They indicated that heterosis was manifested in yield crosses for many studied traits.…”

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.

The main objective related to heterosis breeding is to improve the oil content and seed yield of newly developed hybrids of sunflower (Helianthus annuus L.) using selected parental lines. The present experiment involved of four CMS lines and six testers which were crossed in line x tester fashion to estimate the heterosis for seed yield and yield contributing traits in sunflower. The resulting 24 hybrids were evaluated in two replications of randomized block design over two commercial checks LSFH-171 and LSFH-35 during Kharif 2018 at Oilseed Research Station, Latur. The morphological observations on ten quantitative characters were recorded. Range of standard heterosis in 24 hybrids over check, LSFH-171 ranged from-6.42 to 31.74, whereas the other check, LSFH-35 showed range from-13.56 to 13.56 for oil content while the extent of heterosis for seed yield in hybrid over LSFH-171 ranged from-20.51 to 37.18 while over the other check, LSFH-35 ranged from-6.06 to 62.12. Hybrid PET 89-1 x EC-601951 R exhibited a significant negative heterosis for early flowering and days to maturity over both checks. The hybrids viz., CMS 17 A X EC-601951 R, PET 89-1 x RHA-1-1 recorded a high significant heterosis in desirable direction over both standard checks, LSFH-171 and LSFH-35 for yield and yield contributing traits. These better performing hybrids can be used for exploiting hybrid vigour and needs to be evaluated in future sunflower breeding programme.

“…These traits might be utilized for heterotic expressions in sunflower genotypes. Non additive gene effects have been reported for plant height (Mohanasundaram et al, 2010) for head diameter (Karasu et al, 2010) for 100 achene weight (Karasu et al, 2010), for average yield (Dudhe, 2011).…”

Pakistan is deficient in edible oil production. The sunflower being an important oilseed crop due to better oil composition, short duration as a cheapest source of energy and major component of our daily diet can be used for overcoming the gap. In this experiment combining ability was computed for achene yield and its related trait. 15 Genotypes of sunflower were crossed by using line × tester pattern. Out of 15 genotypes, A6, A7, A10, A11, A12, A17, A19, A20, A21 and A26 were taken as females (lines) and A8, A9, A16, A18 and A22 were taken as male (testers) in this experiment. 50 Crosses were made. The parental and F1 cross seeds was sown in randomized complete block design in 3 replications in next growing season. The data was recorded for number of leaves/plant, leaf area, plant height, head angle, fresh head diameter, dry head diameter, No of achenes/head, average yield/plant, 100 achene weight and harvest index. The recorded data was used to estimate the genetic variation among the genetic material. Line × tester analysis was used for estimating combining ability effects of sunflower genotypes. Analysis of variance, Line × Tester and Crosses vs parents showed highly significant differences among the sunflower accessions. Significant and positive GCA was found among lines A10, A21 for average yield and A17, A26 for 100 achene weight. Among testers significant and positive GCA values were found in A9 for average yield, A18 for 100 achene weight. Dominance variance represented that the ratio of GCA: SCA variance for all of the investigated traits is more than unity. All the lines had highest contribution to the total variance which indicated the presence of maternal effects. The findings suggest that crosses can produce heterotic effects which can be utilized for developing sunflower hybrids with high yield potential.
