Pakistan is inadequate in vegetable oil, and an enormous amount is spent on its import. This is due to the lack of local varieties of oilseed crops in the country. Sunflower (Helianthus annuus L.) is used as a supreme oilseed crop due to its higher oil content. Its hybrids are popular due to its cross-pollinated mode. The present study was conducted for the evaluation of crosses that were better in oil and yield-related traits. For this purpose, 8 parental genotypes were collected, including 5 female and 3 male parents. The subsequent Line × Tester breeding scheme crossed these parental genotypes. Fifteen crosses and eight parental lines were evaluated in Randomized Complete Block Design by using three repetitions. At maturity, data was collected for the following traits such as head diameter, time to bud formation, time to flower initiation, time to maturity, leaf area, plant height, no. of leaves per plant, no. of ray florets per head, 1000 achene weight, achene yield per plant, protein contents and oil contents. Crosses having better yield were selected. Among parents, lines 3-A, 11-A, and 23-A, while testers 79-R and 20-R were the best general combiners for head diameter, time to bud formation, time to flower initiation, time to maturity, leaf area, plant height, number of leaves/plants, 1000 achene weight, achene yield/plant and oil contents. SCA effects showed that cross combination of 12-A × 20-R, 11-A × 78-R, and 20-A × 79-R was best for time to bud formation, the number of leaves per plant, 1000 achene weight, plant height, time to flower initiation and oil contents, respectively. The information obtained from the hybrids can be used in further breeding programs.

“…Cross 23-A × 20-R exhibited as good specific combiner for achene yield/plant among crosses as shown in Table 4. Hladni et al (2011), Imran et al (2015), Singh et al (2017, Lakshman et al (2019) also reported similar findings.…”

“…Ghaffari et al (2011) reported similar results, although their figures were on the upper side, up to 48% oil content. The difference can be attributed to the fact that their work used a different set of germplasm and environments as reported by Hladni et al (2008) and Rondanini et al (2003). However, five of these hybrids were not significantly different from the highest oil content check variety CH3 (Table 1).…”

“…Seed oil percentage of 38% to 54.4% and protein percentages of 15% to 17% have also been reported (Keshta et al, 2008). However, these traits have been reported to be influenced by the germplasm and the environment in which they were evaluated (Hladni et al, 2008;Rondanini et al, 2003). This means that values recorded from elsewhere cannot be generally applied although they might be from the same germplasm set.…”

“…Studying gene action among inbred lines, Ortis et al (2005), Kumar et al (1998), Dagustu andGoksoy (2002), Shrikanth (1996) and Alba et al (1985) reported additive gene action to be important for days to 50% flowering, seed yield and seed oil content. However, given the aforesaid environmental influence on the traits (Hladni et al, 2008;Rondanini et al, 2003) and the specificity of inheritance information to a set of germplasm and environment (Falconer and Mackay, 1996), the need to evaluate germplasm in the recommendation domain remains important in for cultivar development in any given breeding programme.…”

Information on the performance and gene action of sunflower traits is still scarce in southern Africa despite the crop's increasing importance and the growing demand for adapted cultivars. To generate this information, 30 malesterile lines were cross-bred to a restorer line generating 30 experimental hybrids. The hybrids and three check varieties were evaluated in South Africa, Zambia and Zimbabwe. Data was analysed using REML procedure in Gen-Stat®. Significant differences (P<0.05) were observed for grain yield traits, oil content and days to 50% flowering. Grain yield ranged between 1700 kg ha -1 and 4278 kg ha -1 , 1000-seeds weight between 59.4 g and 89.3 g, oil content between 36.6% and 44.6%, and days to 50% flowering between 55.5 and 68.0 for the hybrids but going up to 70 for the control varieties. Five hybrids were ranked above the highest performing check variety for grain yield. Two hybrids, HV9120 and HV9132, significantly outperformed the highest check variety by up to 19.6% and the lowest check variety by up to 91.6%. Oil content showed similar trends with eight hybrids having up to 6.8% yield advantage over the highest check variety and 19.3% over the lowest check variety. The high yields were attributed to heterosis and indicated the high potential for grain yield and oil content from the current germplasm set. The presence of high yielding hybrids with shorter days to 50% flowering, such as HV9132, HV9127, HV9128 and HV9135, showed that it was possible to breed for the short growing season, characteristics of most southern African areas, without compromising grain yield. General combining ability (GCA) effects were significant for all the traits indicating the importance of additive gene action for the traits. Parental lines KP1235, KP1304 and KP1290 that showed desirable GCA effects for at least three of the important traits, were selected for inclusion in the breeding programme for cultivars adapted to the region.
