“…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.…”

“…It was determined that heterotic effects for SCY, FS and GP were mostly negative direction whereas numerous cross combinations showed positive heterosis and heterobeltiosis for FF, FL and Rd. Our results are similar to the findings of Solanki et al (2014) and Khokhar et al (2018).…”

“…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).

The objectives of this study were to determine the heterosis, combining abilities, proportional contributions, genetic components and heritability measurements of some yield, its components and fiber quality characters for six genotypes belong to Gossypium barbadense, L viz., Giza 95 (L1), Giza87 (L2), and Giza93 (L3), which used as a parental lines (L) as well as, Suvin (T1), Karshenky (T2), and 10229 (T3) which used as a testers (T), by using line x tester analysis (LxT) across three locations i.e. Sakha, Sids and Shandweel during 2017 and 2018 seasons. The variances due to the genotypes, locations (Loc.), parents (P), crosses (C), (P vs. C), L, T, (parents x loc.) and (P vs. C x loc.) were significant for most traits under study. Among the parents, Giza 95 (L1) and Karshenky (T2) were highest yielding parents for most studied yield traits, Giza 87 (L2) and Suvin (T1) for most studied fiber traits. According to useful heterosis and desirable specific combining ability effects estimations, the promising recombination's i.e., (L1xT 1), (L2xT 2), (L3xT 1), (L3xT 2) and (L3xT 3) were the highest values for most studied traits. Proportion contribution of testers were the high values for No. of bolls/plant, seed cotton yield per plant, boll weight and fiber strength traits. Meanwhile, lines contributions were the highest for other traits. The non-additive genetic effect was larger than additive ones for NB/P, SCY/P, LY/P and length uniformity index. M eanwhile, heritability in broad sense (h 2 b %) were higher than the values of narrow sense (h 2 n %) for all characters under study.
