“…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) .…”

“…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 criteria for the global cut flower trade are good plant growth, the maximum number of flowers, coupled with a good stem length and flower size (Nair et al 2002;Gurav et al 2005). There are some important fac-tors that affect the cut sunflower marketability: the diameter of the inflorescence and length of the stem (Cvejić et al 2017).Two types of sunflower varieties are used for the cut flower market. The first type is a single-stem sunflower that tolerates dense planting.…”

The aim of this research was to determine the optimum planting density for the production of high-quality cut flowers with desirable characteristics. 25 single-stem ornamental sunflower genotypes were planted at different densities and evaluated for flowering time, flower diameter, and stem circumference and length over a two-year production cycle. Three spacing patterns were used: 25 × 25 cm, 30 × 30 cm, and 70 × 30 cm, which led to the planting densities of 160 000, 90 000, and 60 000 plants/ha, respectively. The plant density had the most important effect on the stem circumference, flower diameter, and stem length (total variation 52, 60, and 58%, AMMI analysis) and a small effect on the flowering time (total variation 1%, AMMI analysis). Based on environment-focused scaling, all high-density environments could be suitable for the production of single-stem sunflower genotypes. The results demonstrated the adaptation of several sunflower genotypes G9, G11, G12, G21, and G22 as the most suitable based on the optimum flower diameter, stem circumference, and stem length. These results may lead to progress in growing ornamental sunflowers as a cut flower.

“…Line A-6 (3.337) exhibited highly significant positive GCA effects, which is desirable for OC. The tester A-8 (0.862) exhibited significantly positive GCA effects for OC (Cvejić et al, 2017). Line A-4 (1.238) exhibited significantly positive GCA effects for the desirable PC.…”

The present research was conducted in the Department of Plant Breeding and Genetics, University of Agriculture Faisalabad. Six lines and four testers were sown, and 24 crosses were generated. The seeds of these crosses were sown in a randomized complete block design (RCBD) with three replications and data for several morphological traits, including the number of days to flowering, plant height, number of whorls per head, head diameter, number of seeds per head, number of leaves per plant, achene yield per plant, 100-seed weight, oil content and protein content were recorded. Data were analyzed using analysis of variance and line × tester analysis. General combining ability (GCA) and specific combining ability (SCA) for traits mentioned above were evaluated. Lines with crosses showing high values of GCA and SCA were selected for further breeding programs. The recorded data were further subjected to analysis of variance, GCA and SCA to determine genetic variability and association among the characters. The results showed that the parental lines A-1, A-2, A-7 and A-8 showed good potential for most of the traits so that they could be taken to further breeding programs. The crosses A-5×A-10 and A-2×A-7 could be used for hybrid development.
