“…Sheoran, Amit [ 25 ] and Ghaffari, Gholizadeh [ 26 ] reported more adaptive and stable hybrids with a high mean, a regression coefficient (b i ) near unity, and deviations from the regression (S 2 d i ) near zero on seed yield. Tyagi, Dhillon [ 27 ] reported stable sunflower hybrids for seed yield; Tabrizi, Hassanzadeh [ 28 ] reported stable hybrids for oil yield; Neelima and Parameshwarappa [ 29 ] reported stable hybrids for head diameter, number of filled seeds per head, 100 seed weight, and seed yield per plant. By and large, hybrids that were shown to be stable for seed yield also demonstrated stability for one or more yield component traits.…”

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.

“…Tan & Tan (2011) and Tyagi, Dhillon, & Kaushik (2018) showed significant general combining ability for plant height, seed number per head, 1000-seeds weight and seed yield. Abd El-Satar (2017) indicated the importance of both additive and non-additive gene action in controlling 1000-seeds weight and oil percentage, while Mohyaji, Moghaddam, Toorchi, & Valizadeh (2014) and Neelima & Parameshwarappa (2017) stressed the preponderance of additive type of gene effects and non-additive gene effects for oil percentage.…”

Twenty eight hybrids derived from four CMS lines and seven restorer lines along with two checks were evaluated in randomized block design at three locations for G x E interactions and stability parameters. Stability analysis revealed that genotype x environment interactions were highly significant for all the eleven traits which indicated differential response of genotypes to varied environments. Cross combinations SVCMS-1 x SVSR-3, SVCMS-1 x SVSR-5, SVCMS-2 x SVSR-2, SVCMS-2 x SVSR-4, SVCMS-3 x SVSR-2, SVCMS-3 x SVSR-3, SVCMS-3 x SVSR-7, SVCMS-4 x SVSR-7 and check Phule Raviaj had significantly higher mean than population mean and regression coefficient less than unity which indicated their stable and wide adaptability to poorenvironment, while, hybrids, viz., SVCMS-1 x SVSR-7, SVCMS-2 x SVSR-3, SVCMS-2 x SVSR-6, SVCMS-3 x SVSR-1, SVCMS-3 x SVSR-4, SVCMS-3 x SVSR-5, SVCMS-3 x SVSR-6, SVCMS-4 x SVSR-1, SVCMS-4 x SVSR-5 SVCMS-4 x SVSR-6 and check LSFH-171 were with high mean, regression coefficient more than unity (bi>1) with non-significant least deviation from regression line indicating their specific adaptation to favorable or rich environments.
