“…TIPO-1 × CIM-600 was the best specific combiner for fiber fineness. When greater value of SCA as compared to GCA effects than non-additive type of gene action was influenced for fiber fineness similar results was found by Sultan et al, (2018); Ali et al, (2014). For most of the traits like number of monopods per plant, boll weight per plant, seed cotton yield, number of nodes per plant, 1 st fruiting node, intermodal distance, ginning out turn percentage, cotton seed yield, seed index, fiber uniformity, plant height, fiber strength, fiber length and fiber fineness had more value for dominance variance same results was also found by Gnanasekaran et al, (2019) and Puspito et al, (2015).…”

Cotton is very important crop regarding the global trade. It is grown for its fiber and edible oil in Pakistan. It contributes 1.5 percent to GDP and 69 percent in foreign exchange. There is need to enhance the yield per unit area of cotton by developing high yielding and stress tolerant varieties. In breeding program the parents and their crosses are selected on the basis of their combining ability. Combining ability analysis is performed to identify the general and specific combiner for yield attributed traits. This research was performed for evaluation of four lines as female parents (C-1, CIM-616, TIPO-1 and CYTO-608) and three testers as male parents (NIAB-1048, CYTO-124 and CIM-600) of cotton (Gossypium hirsutum L.). The traits such as plant height, first fruiting node, seed cotton yield, monopodial branches, sympodial branches, ginning out turn percentage, number of bolls per plant, height to node ratio and cotton seed yield was tested. The general combining ability of parental lines and specific combining ability of the F1 cross will be determined for yield related traits. The genotypes with good general combining ability and specific combining ability further exploited for hybrid/variety development programs. For most of the traits like number of monopods per plant, boll weight per plant, seed cotton yield, number of nodes per plant, 1st fruiting node, intermodal distance, ginning out turn percentage, cotton seed yield, seed index, plant height, fiber strength, fiber length, fiber uniformity and fiber fineness value had more value for dominance variance. The higher effects of GCA and SCA indicated that there is the role of additive and non-additive gene action for inheritance of traits.

“…The crosses Giza 96 ×Karshenky, Giza 94 × Pima S7, Giza 92 × Pima S7 and Australy 13 × Karshenky were significant and positive (desirable) for most yield traits under study, while, the crosses Giza 96 x Giza 92, Giza 94 x Australy 13, Giza 92 × Australy 13, Giza 92 x Karshenky and Giza 92 x Pima S7 were significant (desirable) for most fiber traits. These results are in common agreement with the results obtained by many authors among them Abd El-Hadi et al (2005), Imran et al (2012), Simon et al (2013), Sultan et al (2018), AL-Hibbiny et al (2020) and Mokadem et al (2020).…”

“…On the other hand, narrow-sense heritability (h 2 n) was low to moderate for most of the studied traits, which may be ascribed to the opposite direction of additive and dominance variances, narrow-sense heritabilities were ranged from 5.62% for micronare reading to 58.17% for lint cotton yield plant -1 , respectively. The same findings were reported by Amein et al (2013), Sultan et al (2018), Balcha et al (2019), Mokadem et al (2020), Gnanasekaran and Thiyagu (2021) and Moiana et al (2021).…”

six cotton varieties belong to (Gossypium barbadense L.) growing seasons 2020 and 2021. The F1 hybrids and six cotton varieties Giza 96, Giza94, Giza 92(Egyptian cotton) and Australy13, Karshenky and Pima S7 (another varieties) were growing in 2021 season in a randomized complete blocks design (RCBD) with three replications. Obtained results showed that the mean squares of parents and crosses were highly significant for all traits under study. The mean squares due to general combining ability (GCA) and specific combining ability(SCA) were highly significant for all traits under study except lint percentage at specific combining ability. The crosses Giza 96 × Karshenky, Giza94 × Australy13 and Australy13 × Karshenky were significant desirable heterosis relative to mid and better-parent for most yield traits under study, while, the crosses Giza 96 x Pima S7 and Giza 92 × Karshenky were significant desirable heterosis relative to mid and better-parent for most fiber traits under study. Highest broad-sense heritability estimates was observed in case of seed cotton yield plant -1 with value of 96.81% and the lowest value was for lint percentage with value of 54.26%, while, narrow-sense heritability (h 2 n) was ranged from 5.62% for micronare reading to 58.17% for lint cotton yield/plant, respectively.In general, Australy 13 and Karshenky can be used in breeding programs for improving high yielding varieties, while Giza 92 and Giza 96 can be considered as excellent parents for the production of new varieties characterized with best fiber properties.

“…The GCA mean squares were higher than SCA for majority traits which revealed that additive genes controlled the inheritance. Sultan et al, (2018) cleared that the cross combinations Pima x Giza 67, Pima x Giza 86 and Pima x Giza 68 exhibited mean values and exceeded other combinations for yield and its components traits. The cross combination Pima x Giza 68 recorded significant desirable values over better parents heterosis for seed cotton yield/ plant, lint yield and lint percentage.…”

The present study was carried out at Sakha Agricultural Research Station, Cotton Research Institute, Agricultural Research Center, Egypt, during the two successive seasons 2018 and 2019. Six cotton varieties belong to (Gossypium barbadense L.). Three of them are Egyptian cotton varieties; Giza 89, Giza 93 and Giza 96. The other three varieties are Pima S4, Pima S6 and Suvin. They were crossed in a half diallel mating to produce 15 F1 hybrids in 2018 season. The F1 hybrids and six cotton varieties were growing in 2019 season in a randomized complete blocks design with three replications. The Results showed that the mean squares of the genotypes, parents, crosses and parents versus crosses were significant and highly significant for all studied traits except No. of bolls/plant at parents and micronaire reading at parents versus crosses. The results illustrated that the mean squares of general combining ability (GCA) and specific combining ability (S.C.A.) were significant and highly significant for all studied traits except micronaire reading at specific combining ability (S.C.A.). The parental genotypes Giza 96 and Giza 89 gave significant (desirable) GCA effects for most yield traits. Giza 96 and Suvin exhibit significant and positive (desirable) GCA effects of some fiber properties. The crosses Giza 89 x Pima S4, Giza 96 x Pima S6 and Giza 96 x Suvin recorded significant and positive (desirable) SCA effects for most yield traits, while the crosses Giza 89 x Giza 96, Giza 96 x Suvin and Giza 89 x Suvin showed significant (desirable) SCA effects for some fiber properties. following crosses
