“…The three hybrids recorded significant positive heterosis over the better parent. These results are in agreement with the results reported by Shamshad et al (2016) and Harun (2019). Linoleic acid constitutes unsaturated fatty acids which are desirable from the health point of view.…”

“…Heterobeltosis ranged from 48.49% (A 11 Â Rf 18 ) to 75.00% (A 5 Â Rf 9 ). Negative heterosis for stearic acid in sunflower has also been reported by Ferfuia et al (2012), Shamshad et al (2016) and Harun (2019).…”

“…The predominant role of SCA has been determined for yield and other yield contributing components in sunflower Aleem et al (2015) while others explained the superior effect of GCA effects over SCA for various traits contributing towards yield (Machikowa et al, 2011). Higher SCA variances as compared to GCA variances were also reported for achene yield per plant, seed and oil yield per hectare (Memon et al, 2014), palmitic, stearic, oleic acid and linoleic acid (Shamshad et al, 2016;Rizwan et al, 2020). Higher GCA variances as compared to SCA variances were also reported for achene yield per plant (Kholghi et al, 2014), palmitic acid, stearic acid and oleic acid (Joksimovic et al, 2006).…”

Twenty-one hybrids of sunflower were produced by crossing 7 introduced cytoplasmic male sterile lines (CMS-lines) with 3 restorer lines (RF-lines) using line × tester mating design. The twenty-one hybrids, three restorers, seven maintainer lines (B-lines) were evaluated. The experiment was conducted in a randomized complete block design of three replications. Mean squares due to genotypes, parents (P), crosses (C), lines (L), testers (T), P vs. C, for stearic acid and line × tester for palmitic acid. The inbred lines and their F1 hybrids differed significantly in their mean values of the traits under study. The variances due to specific combining ability (SCA) were higher than general combining ability (GCA) variances for all the studied traits, showing non-additive type of gene action controlling the traits. Non-additive type of gene action can be utilized for varietal improvement through heterosis breeding. Heterosis values for seed yield plant−1 were positive and highly significant relative to both the parental mean (17.68–72.38%) and the better parent (−2.86–56.842%). Significantly and negative heterosis was recorded in the case of linoleic acid relative to the parental mean (−81.24 to −38.02%) and better parent (−66.24–22.87%). With oleic acid, the heterotic effect ranged from −14.18 to 39.59% (parental mean) and from −15.06 to 38.72% (better parent). Therefore, these results are valuable for the improvement of quantitative as well as qualitative traits in sunflower breeding material to fulfill the edible oil requirements.

“…Importantly, negative heterosis of this traits are desirable and the highest negative heterosis for lauric acid and stearic acid was found from the cross Dacca-1 × China Badam, myristic acid from the cross Dacca-1 × GC ( 24)-1-1-1, palmitic acid from the cross China Badam × GC ( 24)-1-1-1, and arachidic acid from the cross China Badam × Binachinabadam-4. Similar negative heterosis for saturated fatty acid was also reported in sunflower (48). Importantly, in most of the cases different cross combination exhibited higher superiority in hybrid, therefore, they can be used in isolating potential lines and to break oil decreasing and low quality barrier in groundnut.…”

Development of a variety having high oil content and desirable fatty acid compositions is a major objective of groundnut (Arachis hypogaea L.) breeding programmes. To study the gene action (through combining ability) and heterosis for oil and fatty acids, an experiment was conducted using a 4 × 4 full diallel method. Four parents and their 12 F1 hybrids were evaluated following a randomized complete block design. Data were recorded for oil, fatty acids and oleic-linolenic (O/L) acid ratio. Highly significant genotypic variation was found among the parents and their F1 hybrids for the studied traits. The combining ability studies (general, specific and reciprocal) reflected that the oil and fatty acid traits were controlled by both non-additive and additive genes having significant maternal effects. Results also revealed that the parent China Badam was the best general combiner for oil, linolenic acid and O/L ratio whereas the parent Binachinabadam-4 for oleic and linoleic acids. Best SCA performance was found from the cross Dacca-1 × China Badam and Binachinabadam-4 × China Badam for oil, oleic- and linolenic-acid contents. Significant heterosis for oil content was observed in F1 hybrids obtained from the cross Binachinabadam-4 × China Badam and its reciprocal cross. The cross China Badam × GC (24)-1-1-1 showed a higher O/L ratio (>4) along with lower level of saturated fatty acids. Therefore, these crosses could be exploited in future breeding programmes to develop new lines for higher oil and healthy fatty acid compositions.

The present investigation was conducted to study genetic parameters for sixteen characters viz., days to 50% flowering, days to maturity, plant height, head diameter, leaf length, leaf width, number of leaves per plant, 100 seed weight, volume weight, seed yield/plant, seed length, seed width, stem girth, leaf area index, chlorophyll content and oil content at ICAR-Indian Institute of Oilseeds Research during kharif-2022 and rabi-2022-23, respectively. The study included a total of 50 advanced (BC2F6) interspecific derivatives derived using five diploid annual compatible Helianthus species along with three checks (ARM-243B, DRSF-108 and DRSF-113). Analysis of variance revealed significant differences for all the traits. High variation was observed for plant height and seed yield/plant and lowest was observed for 100 seed weight, oil content and head diameter. The difference between GCV and PCV was low for all the characters indicating less influence of environmental factors on the expression of these traits. High heritability coupled with high genetic advance in percent of mean was observed for plant height, leaf width, number of leaves/plant, volume weight, 100 seed weight, stem girth, leaf area index and chlorophyll content indicating additive gene action in the expression of these traits. Simple phenotypic selection may be effective for improving these characters. High heritability coupled with low genetic advance was observed for days to maturity and oil content suggesting involvement of non-additive gene action in the expression of these traits indicating little scope for further improvement through individual plant selection. The results showed that the experimental material used had a substantial quantity of genetic variability to be used in crop development programs in the future.
