“…Predominance of dominant gene effect was reported previously by Wakode et al (2016) who also reported all three significant non-allelic interactions. Dominance x dominance interaction was reported to be significant in the studies conducted by Akthar et al ( 2010) and Deshmukh et al (2021).…”

“…These results support the fact that simple selection would be effective in developing early flowering types. High and significant additive dominance was previously reported by Akthar et al ( 2010), Khanorkar and Kathiria (2010), Akotkar and De (2014), Wakode et al (2015), and Deshmukh et al (2021) in this trait control. Our results suggested role of complementary gene action in this trait.…”

“…These results advocated the use of either selection or recurrent breeding method in the improvement of this trait. Significant additive gene action was reported by and Wakode et al (2016). Significance of Additive genetic effect (d) and dominance x dominance (l) interaction was earlier reported by Patel et al 2013 andSrikanth et al (2018).…”

The present study on generation means analysis was carried out to uncover genetics of yield traits in okra. To determine the nature and magnitude of gene action six generations (P1, P2, F1, F2, BC1 and BC2) of cross Pusa Sawani x Pusa Bhindi- 5 was assessed. The results revealed that both additive and dominance gene effects were significant in genetic control of yield traits. However, the magnitude of dominance gene effects was significant and higher for seed germination per cent, days to first flower, node to first flower, number of fruiting nodes, plant height and fruit yield per plant. Therefore, heterosis breeding would be effective to improve these traits. Additive genetic effect was significant for days to 50 per cent flower, inter-nodal length, number of primary branches, fruit length, fruit diameter and fruit weight. Result of scaling tests confirmed the role of non-allelic interaction in genetic control of all the yield traits analysed. The opposite sign of dominance (h) and dominance x dominance interaction (l) for many yield traits suggested role of duplicate type of epistasis, while few characters exhibited complementary type of epistasis. For improving traits with higher fixable (additive and additive x additive) component of genetic variation, pedigree method of breeding would be useful. For traits showing significant values of both additive and non-additive gene effects, improvement can be done by either recurrent selection or bi-parental mating system in segregating generations followed by selection.

“…It is clear from the combining ability study that the GCA variance was lower than the SCA variance, leading to the character's value of 0.363. This showed the participation of additive genes for this trait, which was also supported by the results of (Wakode et al, 2016). The data showed that the range for the mean number of days till first fruiting was 46.0 to 59.…”

O kra is a vegetable widely grown in hot and subtropical regions. It is a major crop in Pakistan, but average yields are low compared to other countries (Bhatt et al., 2015). Farmers begin growing the Kharif crop in January as an off-season early crop in order to gain high prices, despite the fact that it is a warm season. For the Kharif crop to function at its best, high soil temperatures as well as high daytime Abstract | The present study was conducted to assess combing ability and genetic analysis in Okra. Twentyeight okra genotypes (5x5 diallel crosses) and checks were screened for high yield and early maturity in a randomized complete block design. Highly significant differences were observed for most traits, except stem diameter and marketable fruit diameter. Among genotypes, G10 flowered earliest (41.5 days), G22 had longest internodes (3.59cm), G16 had heaviest fruits (9.65g), and G14 had longest and thickest marketable fruits (13.8 cm, 1.74cm). Combing ability analysis revealed that non-additive gene action was involved in controlling all traits. Non-additive gene action was important for all traits, and P2 and P3 were good general combiners. G8 and G14 were superior crosses due to high per se performance and significant SCA effects. Heritability analysis suggested that the selection of the studied traits should not be based on phenotypic performance. A heterosis study revealed that most of the crosses outperform the checks, and hence could be used in future okra breeding programs. The estimated inbreeding depression revealed that the majority of the traits showed negative inbreeding depression due to selfing, thus least affected by selfing. Thus from our study G8, G14 and G23 could be identified as the best-performing crosses for yield-associated traits. Hence should be involved in a variety of development programs to improve the quantitative and related traits of Abelmoschus esculentus L.

“…The studies intended to determine the combining ability is not only for information regarding the choice of parents but also for the production of superior lines or hybrids. The general combining ability and specific combining ability effects are the foundations for any fruitful breeding programme (Wakode et al, 2016). The common approach of selecting the parents on the basis of per se performance is not a good indicator of their superior combining ability (Allard, 1960).…”
