The sunflower is a remarkable oilseed crop due to better oil composition and short duration. In this experiment combining ability was computed for achene yield and its related trait. Fifteen 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). The parental and 50 F1 crosses seed was sown in randomized complete block design in 3 replications in next growing season. The data was recorded for leaves/plant, leaf area, plant height, head angle, fresh head diameter, dry head diameter, number of achenes/head, average yield/plant, 100 achene weight and harvest index. The recorded data was used to estimate the genetic of descriptive traits among the genetic material. Heterosis study revealed that A19 × A22 was best hybrid for plant height. A21 × A8 performed well for number of achenes per head and directly involved in increasing yield. A7 × A8 hybrid combinations expressed positive and significant SCA values for average yield. The intermediate inheritance pattern was observed for all traits. It can be concluded that investigated material can be efficiently used for the development of high-yielding hybrids along with genetic improvement of sunflower accessions for different traits.

“…Crosses showing highest 100-achene weight might be utilized in producing high yielding hybrids. Jocković et al (2018) and Khan et al (2008) had reported variability for 100-achene weight ranged from 5.51 to 10.50 g in sunflower. The abovementioned findings are in pars with these researchers.…”

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.

“…Combining ability of parental lines should be estimated to find the best hybrid combinations. Furthermore, estimation of gene effects could be done by analyzing combining ability values based on F 1 mean values (Jocković et al, 2018).…”

“…Jocić, Miladinović, & Kaya (2015) analyzed four male sterile lines and 10 testers and found additive gene effects for seed yield. However, Jocić, Miladinović, & Kaya (2015), Jocković et al (2018), and Makanda et al (2014) analyzed gene effects of inbred lines using line x tester method and they showed that non-additive gene effects were more important for seed yield. Larièpe et al (2017) also observed the after that gene component was more important than the additive component in managing seed yield in sunflower.…”
