“…This is maybe due to the aggregation of favorable genes from different traits in these superior backcrosses. The genetic variability among bi-parental sunflower crosses is consistent with those reported by Shinde et al (2016), Abd EL-Satar et al (2017) and Lakshman et al (2019).…”

“…Similarly, Azad et al (2016 concluded the predominance of the non-additive gene action in inheritance of all the studied traits except for days to maturity. Additionally, many of the yield-attributing traits in sunflower are under the influence of non-additive gene action as reported by Shinde et al (2016), Abd EL-Satar et al (2017, Lakshman et al (2019) and Ahmed et al (2019). Consequently, according to the previous authors, the improvement of these traits can be performed by using hybrid varieties.…”

A field experiment was conducted in the contrasting locations of Kafr-El-Hamam/Sharkia and Al-Arish/North Sinai agricultural research stations of the Agricultural Research Center in Egypt. We estimated the additive and dominance genetic variances, as well as heritability in the broad and narrow senses for sunflower yield and its attributes in the cross L350 x L355 using North Carolina Design-III. The magnitude of the additive variances for all studied traits at both locations in proportion to the phenotypic variances was larger than the dominance variances. The average degree of dominance was greater than the unit, as also confirmed by the high narrow-sense heritability for most of the studied traits. The genetic improvement may be achieved through the selection of genotypes with larger head diameter and heavier seed weight which also showed moderate to high values of narrow-sense heritability. Thirty-two sunflower backcrosses were grouped into eight distinct clusters/groups by canonical analysis.

“…Non-additive gene action was reported for volume weight and test weight (100 seed weight) in sunflower which were similar to earlier reports by Mohanasundaram et al (2010). Similarly, for yield per plant and oil content were also governed by non-additive gene action in sunflower which were in accordance with Reddy and Madhavilatha (2005), Parameshwarappa et al (2008), Dudhe et al (2011), Patil et al (2012, Jondhale et al (2014) and Shinde et al (2016).…”

“…Whereas for days to 50 per cent flowering higher magnitude of GCA variance than SCA variance was observed indicating the presence of additive gene action for this character which is in accordance with Ortis et al (2005). For plant height and head diameter non additive gene action was reported by Manivannan et al (2005), Reddy and Madhavilatha (2005), Pavani et al (2006), Parameshwarappa et al (2008), Mohanasundaram et al (2010), Dudhe et al (2011) and Shinde et al(2016) in sunflower. With respect to days to maturity nonadditive gene action was earlier reported in sunflower by Reddy and Madhavilatha (2005), Pavani et al (2006), Mohanasundaram et al (2010) and Shinde et al (2016).…”

Abstract:The restorer lines are used to get fertile hybrids in hybrid seed production system of sunflower. Improvement of R-lines for fertility and oil content of sunflower is required to get desirable hybrids upon crossing. In the present study, 6 restorer lines were crossed in full diallele and both direct and reciprocal crosses along with parents were evaluated for their combining ability. The analysis of variance revealed higher magnitude of SCA variance than GCA variance for all the characters studied except for days to 50 per cent flowering. Among six parents, GMU-520 and R-GM-41 were best general combiner for plant height, head diameter, test weight and leaf size in the desired direction. However, GMU-520 has advantage of yield per plant and oil content. From 15 direct crosses R-GM-41 x R -GM-49 exhibited significant specific combining ability for viz., days to 50 per cent flowering (-1.08), plant height (13.69), head diameter (4.79), leaf size (0.74), yield per plant (17.14), volume weight (2.54), test weight (1.75) and oil content (0.34) followed by RCR-630 x GMU-520, R-GM-41 x EC-602060, R-GM-49 x GMU-520 and EC-602060 x GMU-520 each exhibiting good specific combining ability for majority of characters. Among reciprocal crosses R-GM -41 x RCR-8 exhibited a high reciprocal effects for head diameter (4.57), yield per plant (15.16), test weight (2.02) and leaf size (0.75).

“…Line A-1 (0.31) exhibited significantly positive GCA effects for AYP, which is desirable. The tester A-7 (0.16) showed significantly positive GCA effects, a desirable trait for AYP (Shinde et al, 2016). Line A-6 (3.337) exhibited highly significant positive GCA effects, which is desirable for OC.…”

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.
