“…Increased seed yield per plant is the ultimate objective in crop breeding hence high heterosis for seed yield is always looked for two crosses viz., CMS 17A x EC-601951 R (37.18 %, 62.12 %), and PET 89-1 A x RHA 1-1 (15.38 %, 36.36 %) exhibited significant positive high heterosis over both the standard checks. Similar result was also reported by Patil et al, (2012), Patil et al, (2017) and Thombare et al, (2007). High volume weight is having direct relation to increase the weight of seed.…”

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.

“…The magnitude of SCA variance was greater than GCA variance for most of the traits except seed oil content indicating predominance of non-additive variance controlling the expression of these traits. Similar results were reported by Karasu et al (2010), Dudhe et al (2011), Hladni et al (2011) and Patil et al (2017).…”

“…The important of non-additive variances were verified by the dominance degree ratio, which was more than unity for all studied traits (Table 7). The preponderance of non-additive gene action for these traits was supported in the results of Karasu et al (2010), Dudhe et al (2011), Hladni et al (2011) and Patil et al (2017.…”

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.

“…It is originated in North America and largely grown in Ukraine, Russia, European Union, Argentina, China and India. It is an important source of edible and nutritious oil (about 38-50% by composition) and is a rich source of linoleic acid and oleic acid which helps to remove cholesterol deposition in the coronary arteries and thus is good for heart patients [1].…”

To estimate the extent of heterosis in sunflower for earliness and oil content, ninety-six hybrids were tested in line × tester mating fashion consisting of six CMS lines and sixteen testers (10 R × R S3 high oil content restorer lines and 6 R × R S4 early restorer lines) were evaluated in a simple lattice design, simultaneously parents were also evaluated in RCBD design at Main Agricultural Research Station, Hebbal, Bangalore during summer 2020-21. Analysis of variances revealed that the genotypes, parents, lines, crosses and parent vs crosses showed highly significant differences for earliness and oil content. The high oil content hybrids viz., CMS 903A × 5-2-1 (79.50 days) and CMS 903A × 44-2-1 (80 days), and early hybrids i.e., CMS 903A × 2-3-1-2 (76 days) and NDCMS4A × 2-3-1-2 (78.50 days) recorded good mean performance and high significant heterosis for earliness in a negative direction over the standard check KBSH-44 (National check). With regard to the oil content, the high oil content hybrids like NDCMS2A × 30-10-1 (41.63%), CMS 903A × 38-4-1 (41.61%) and CMS 234A × 38-4-1 (41.61%), in the case of early hybrids viz., CMS 911A × 25-2-4-2 (41.11%), CMS 911A × 4-1-3-1 (39.69%) and CMS 911A × 2-3-1-2 (39.59%) were showed good mean performance and highest significant standard heterosis over the standard checks like KBSH-44 and KBSH-53. Similarly, regarding the seed yield plant-1 (g), the hybrids viz., CMS 911A × 8-5-5-1[E] (70.60g), CMS 234A × 31-1-1[H] (66.20g) and CMS 1103A × 30-10-1[H] (65.95g) were manifested desirable mean performance and also higher significant heterosis over standard check KBSH-44.
