“…The use of heterosis breeding offers the possibility of improving the quantitative traits in cross-pollinated crops. Sunny et al [ 21 ] reported that per se evaluation is often ineffective for parental selection on yield-related traits due to their polygenic nature. The selection can be more biased due to unstable performance across environments and weaker vigor due to inbreeding depression [ 22 ].…”

Improving sweet–waxy corn hybrids enriched in carotenoids via a hybrid breeding approach may provide an alternative cash crop for growers and provide health benefits for consumers. This study estimates the combining ability and heterosis of sweet–waxy corn hybrids for yield-related traits and carotenoids. Eight super sweet corn and three waxy corn lines were crossed to generate 24 F1 hybrids according to the North Carolina Design II scheme, and these hybrids were evaluated across two seasons of 2021/22. The results showed that both additive and non-additive genetic effects were involved in expressing the traits, but the additive genetic effect was more predominant. Most observed traits exhibited moderate to high narrow-sense heritability. Three parental lines, namely the ILS2 and ILS7 females and the ILW1 male, showed the highest positive GCA effects on yield-related traits, making them desirable for developing high-yielding hybrids. Meanwhile, five parental lines, namely the ILS3, ILS5, and ILS7 females and the ILW1 and ILW2 males, were favorable general combiners for high carotenoids. A tested hybrid, ILS2 × ILW1, was a candidate biofortified sweet–waxy corn hybrid possessing high yields and carotenoids. Heterosis and per se performance were more positively correlated with GCAsum than SCA, indicating that GCAsum can predict heterosis for improving biofortified sweet–waxy corn hybrid enriched in carotenoids. The breeding strategies of biofortified sweet–waxy corn hybrids with high yield and carotenoid content are discussed.

“…Heterosis, also known as hybrid vigor, is the phenomenon in which the offspring of two genetically different parents exhibit superior traits compared to their parents. The degree of heterosis is influenced by additive and non-additive gene effects (Sunny et al 2022).…”

Eight rice genotypes, including Binam, Hashemi, Deylamani, TH1, Hasani, Saleh, IR75479-199-3-3, and Gohar, were crossed in a line tester mating design to generate breeding populations, assess the general and specific combining ability (GCA and SCA) and identify suitable combinations for yield. 23 genotypes (15 F1s and eight parents) were evaluated in a randomized complete block design with three replications at the Rice Research Institute of Iran during the 2020 cropping season. Analysis of variance revealed significant genotype effects and GCA and SCA mean square values for all the investigated traits, which indicated the genetic diversity of the parental genotypes and the importance of both additive and non-additive gene effects in the inheritance of the studied traits. Results indicated that additive gene action controlled plant height. Meanwhile, non-additive gene action controlled panicle length, number of panicles per plant, heading date, hundred-grain weight, number of grains per panicle, and grain yield. Effects of general combining ability were significant for the panicle length, the number of panicles per plant, heading date, hundred-grain weight, number of grains per panicle, and plant height in all testers. Hasani and Saleh's genotypes demonstrated to be good general combiners for early maturity. Gohar was the best specific combiner to enhance yield components. Hashemi × Gohar was identified as the best combination for improving grain yield and reducing the number of days to heading. The predominance of non-additive types of gene actions related to grain yield and its components suggested that selecting the best plants should be postponed to advanced generation.

“…Because the tiny genetic base is a key bottleneck for breaking the yield plateau, it is vital to boost sunflower seed and oil yield by integrating additional genes from superior lines through recombination breeding. Plant breeders are very interested in genetic variety [ 7 – 9 ]. The more different the parents, the more likely a heterotic cross combination will result in F 1 with a wide range of diversity in segregating generations [ 10 ].…”

Exploration of heterosis is a strategy for enhancing sunflower yield and productivity. In India, the greatest constraints on sunflower production are stagnant and inconsistent yields. By raising them in a variety of ecological conditions, stable per-se performance with the highest yielding potential sunflower hybrids were selected. Sustainable agriculture requires the use of desirable hybrids with high seed yields and oil content too. By making three distinct crossing sets from 32 sunflower genotypes, 11 cytoplasmic male sterility (CMS), and 21 restorer lines, a total of 124 hybrids were developed (comprising both lines and tester). After extensive field evaluation of all hybrids, only eight superior F1s belonging to all three sets, as well as the three national control hybrids KBSH-53, LSFH-171, and DRSH-1, were selected for stability analysis in four agro-ecological regions of West Bengal, India viz., Nimpith, Baruipur, Bankura, and Berhapore. The genetic stability of several phenotypic characters was assessed using statistical models that examine genotype-environment interaction (G × E) in multi-locational yield trials. In this experiment, the performance of hybrids under various environmental circumstances over two-year periods was measured using regression coefficient (bi) and deviations from regression (S2di). With the exception of genotypes CMS-852A × EC-601751 for volume weight (0.9335) and CMS-302A × EC-623011 for head diameter (0.0905) and volume weight (0.6425), all sunflower genotypes for all concerned traits had extremely minor and negligible deviations from regression (S2di), which showed significant values. The genotypes having insignificant values of S2di were more stable. The economic heterosis of these novel hybrids was also quantified. CMS-302A × EC-623011 in which seed yield was recorded 20.90, 20.91, 20.95 and 20.90% higher than DRSH-1 at Nimpith, Baruipur, Bankura and PORS (Berhampur), respectively. The research revealed that CMS-302A × EC-623011, CMS-853A × EC-623027 and P-2–7-1A × EC-512682 exhibited good seed production and stability for critical agronomic parameters in addition to oil content. As a result, the current researches enlighten to find out how stable the expression of important economic traits in sunflower hybrids is.
