“…This was also confirmed by ratio of σ 2 GCA/σ 2 SCA which is less than unity for these characters. The findings of the present investigation for seed yield per plant and its attributing traits are in close conformity with the findings of Priya et al, 2016 [5] ; Saxena and Bisen, 2017 [6] and Virani et al, 2018 [9] . An overall appraisal of gca effects (Table 2) indicated that none of the parents was good general combiner for all the characters studied.…”

“…The ratio of σ 2 GCA/σ 2 SCA was more than unity for plant height and height to first capsule thereby suggesting the presence of additive gene action for the control of these characters. The predominance of additive gene action for plant height and height to first capsule has also been reported by Walter et al (2016) [10] , Mungala et al (2017) [4] and Virani et al (2018) [9] . For days to 50% flowering, days to maturity, number of branches per plant, length of capsule, number of capsules per leaf axil, number of capsules per plant, number of seeds per capsule, 1000-seed weight, seed yield per plant and oil content the sca variance was higher than gca variance which indicated greater role of non-additive gene action in the control of these characters.…”

A line x tester analysis using nine lines and five testers was carried out to study the combining ability and gene action in sesame for seed yield and its related 11 quantitative traits. The partitioning of variances due to the crosses showed that the mean squares due to lines were found significant for all the characters except for number of branches per plant and oil content, whereas mean squares due to testers and lines x testers were found significant for all the characters except for the plant height and number of branches per plant. General and specific combining ability variances showed the involvement of both type of gene actions in the inheritance of these characters. Among the parents, two lines viz., AT-472 and AT-483 and three testers viz., GT-2, GT-3 and GT-6 exhibited good general combining ability effect for seed yield per plant. The cross combination, AT-471 x GT-2 showed significant and positive sca effect for seed yield per plant and involved average x good combining parents. It was followed by AT-464 x GT-4 and AT-472 x GT-3 which involved either good x good or poor x poor combining parents. These crosses have been identified as best hybrids for improving seed yield per plant.

“…Since, high GCA effect attributed to additive gene action, the parent having highly significant and positive GCA effect could be used in breeding program for yield improvement through pedigree breeding. Similar result registered by Vidhyavati et al (2005) [14] , Virani et al (2018) [17] , Karthikeyan et al (2019) [9] , Sirohi et al (2020) [12] and Ghule et al (2022) [6] . The results on specific combining ability effects of crosses for different traits under study are presented in Table 3.…”

The present investigation entitled "Heterosis and combining ability studies in Sesame (Sesamum indicum L.)" were undertaken with the objective to study the heterosis and to estimate general and specific combining ability effects. Among the parents, TBS-05 and TBS-10 were found good general combiner for seed yield per plant. Considering both per se and GCA effect the parents TBS-05 and TBS-10 were found to be best. The highest SCA effect for seed yield per plant was exhibited by cross R-20 x V-13 along with superior SCA effect for six traits like day to maturity, plant height, number of capsules per plant, seeds per capsule, capsule length and oil content. The character test weight had fixable additive genetic variance which can improve by simple selection. The crosses V-13 x TBS-07 and V-13 x TBS-05 with significant SCA effects for seed yield per plant. Better segregants can be obtained from such hybrid combination for seed yield and yield contributing traits.

“…The performance stability of a variety refers to its consistent production in a specific environment over time (Mirza et al., 2013 ). A plant variety's ability to tolerate different stresses (such as temperature extremes, water levels, day length changes, and light intensity) and survive a range of soil conditions is essential for growth and development (Kumaresan & Nadarajan, 2010 ). Genotype and environment interaction (G × E interaction) occurs when plant genotypes respond differently to environmental changes, impacting the relationship between phenotypic and genotypic values.…”

The multi‐environmental trials aid breeders in selecting the best genotypes for specific or general adaptability to different environments before commercial release. This study aimed to assess the stability of 13 new soybean pure lines, along with two controls, in terms of seed yield and important agronomic traits. The assessment was based on a completely randomized block design with three replications across four areas during 2020–2022. Various adaptability methods, including parametric, AMMI, GGE biplot, PCA, and SIIG were employed. The mixed analysis showed that the effects of environment, genotype, and genotype–environment (GE) interaction were significant for most studied traits. The AMMI showed the highest portion of environment (65.89%) in soybean seed yield. Based on all stability parameters, lines 2 and 5 were selected for their average seed yields of 3349 and 3142 kg ha−1, respectively. Additionally, lines 6 and 5 showed the most stability, yielding higher than the average, which were 2992 and 3142 kg ha−1, respectively, according to GGE biplot results. Furthermore, lines 2, 5, and 8 were identified as the ideal genotypes concerning seed yield and other agronomic traits, with high SIIG parameters and yields exceeding the average. Finally, the soybean line 5 was deemed the most suitable due to its higher yield, stability, and early maturity (128‐day growth period). Therefore, line 5 is considered appropriate for its high stability and earliness in various regions of Iran.
