“…It was shown that FF and Rd were managed largely by additive gene effects. Our results were similar to Prakash et al (2018) but Munir et al (2018) and Patil et al (2018) were found non-additive gene effects for FF. This contradiction may be due to genotypic material and different mating design.…”

“…Similar results were reported by Kaleem et al (2016) Also, non-additive gene effects for FL, FS and GP were predominant according to variance ratio of GCA to SCA with below 1. Our findings were in accordance with Khokhar et al (2018); Munir et al (2018); Patil et al (2018). But Prakash et al (2018) revealed that these characteristics were controlled by additive gene effects.…”

“…The ratio of σ 2 GCA / σ 2 SCA could be useful in order to estimate the behavior of a segregating generation. Many researchers reported that seed cotton yield, fiber length, fiber strength and ginning percentage controlled by non-additive gene effect (Khokhar et al, 2018;Munir et al, 2018;Patil et al, 2018). Therefore, selection for improvement should be delayed to late generations (F4-F6).…”

This experiment was conducted in order to estimate gene action, combining ability and heterotic effects for yield and quality characters by the line x tester analysis, involving 5 lines and 4 testers with 20 crosses in cotton (Gossypium hirsutum L.). The ratio of general and specific ability variance revealed non-additive gene action effects for seed cotton yield, fiber length, fiber strength and ginning percentage and additive gene action for fiber fineness and reflectance degree. Claudia, Gloria and Bali 308 with high general combining ability were the best combiner parents and could be used for breeding multi-parent combinations. ST-468 x Claudia, Carisma x Carmen, Bali 308 x Gloria and Bali 308 x Claudia were promising combinations for further selection. Heterosis and heterobeltiosis values of most cross combinations for seed cotton yield, fiber strength and ginning percentage were negative direct. It was concluded that due to non-additive gene actions, it is advisable to select individual plants for seed cotton yield, ginning percentage and fiber traits in later generations (F4-F6).

“…Environments x males x females interaction was also found to be significant for all the characters which indicated variability for specific combining ability among the crosses to the environments for these traits. Tuteja et al, (2006), Shinde et al, (2009), Singh et al, (2014), Patil et al, (2017 and Patil et al, (2018) also reported significant variation for genotypes and genotypes x environments interaction over the environments. Among female parents, none of the parents exhibited significant gca effects over the environments for seed cotton yield.…”

Successful hybrid development work in cotton involves unearthing information of combining ability, heterosis and per se performance of the genetic material. This study involved multi‐environment estimation of combining ability and heterosis along with the stability of per se performance using Bt cotton genetic materials for seed cotton (Gossypium hirsutum L.) yield. Combining ability analysis across environments showed significant effects on the performance of genotypes, general combining ability (gca), specific combining ability (sca), genotype × environment, GCA × environment, and SCA × environment interactions. Combining ability variance revealed the predominance of nonadditive gene actions for seed cotton yield. The mean performance combining ability estimates were varied with the locations for parents as well as for hybrids. In a low yielding environment, the transgenic BGI parents, as well as hybrids, showed superior seed cotton yield levels compared with BGII or non‐Bt versions. There was a significant increase in heterosis noticed in BGII hybrids compared with BGI hybrids in a low yielding environment. The stability parameters showed significant genotype × environment variation and indicated that the stability of the genotype was mainly affected by the genetic background of the material. A positive association was noticed between per se performance and gca effects, heterobeltiosis and sca, and heterobeltiosis and mean of hybrids as the environment`s yield potential increased. The majority of the Bt hybrids showed positive heterosis over a better parent. Among the two versions of Bt transgenic cotton, BGI excelled in per se performance and gca and sca effects for seed cotton yield either in the homozygous form or hemizygous hybrids.
