“…Results indicated that the crosses Giza 96 × Karshenky, Giza 94 x Australy 13 and Australy 13 × Karshenky were significant desirable heterosis relative to mid and better-parent for yield traits under study, while, the crosses Giza 96 × Pima S7 and Giza 92 x Karshenky were significant desirable heterosis relative to mid and better-parent for fiber traits under study. These results were in harmony with those obtained by Karademir and Gençer (2010), Attia (2014), Al-Hibbiny (2015), El-Fesheikawy et al (2015), Sorour et al (2015), Salem (2016) and Said 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 good x good GCA combination could be due to additive and additive types of gene action which is fixable on nature which had significant SCA effects for studied traits. Yahia [32]; Sorour et al [33], Chinchane et al [26] and Yehia and EL-Hashash [34]. This study suggested that information of GCA effects of parent should be considered along with SCA effects and presence performance of hybrid for predicting the value of any hybrid.…”

The objective of this study was to determine the general and specific combining abilities and heterosis of some cotton genotypes for yield, its components and fiber traits using line x tester mating design. Nine parents (six line and three testers) were crossed in a line x tester mating design in 2020 season. Nine parents along with their eighteen F1 crosses were studied in a randomized complete block design (RCBD) with three replications during 2021 at Sakha. Agricultural. Research. Station. Kafr El-Sheikh, Governorate, Egypt. Based on line x tester analysis, the variance due to genotypes, parents, crosses and parent vs. cross exhibited significant differences (P. 0.01) for most yield, yield components and fiber traits. The variance due to GCA of lines x testers and SCA of line x tester interactions were highly significant for most studied traits, indicating the importance of both additive and non-additive gene actions in controlling these traits. The estimates of GCA and SCA effects revealed that the parent and some crosses were having desirable and significantly GCA and SCA effects, respectively. High mean performances and significantly GCA effects values were observed of line Giza 92, Giza 75 and tester Giza 97 for most studied traits, hence, these parents can be used as for generation superior cotton hybrids. The best values of mean performances, SCA effects and heterosis were found in the combinations Giza 94 x Giza 92, Giza 97 x Suvin for most yield and yield components and the cross Giza 97 x (Giza 75 x Sea) for yield and fiber traits. These crosses are considered as the promising crosses to be used in breeding programs for produce hybrid cotton and improvement for these traits in Egypt.

“…The parent (Giza 89 x Giza 86) was the best combiner for boll weight, while the parent (Giza 89 x Sea) was the best combiner for upper half mean. Sorour et al, (2013) found that the best general combiner for most of studied traits was parent (10229 x G. 86). Also the best general combiners for most of studied traits were crosses Hibbiny et al, (2019-a) noticed that the estimates of specific combining ability (SCA) effects for the crosses Giza 90 x Karshenky, Giza 95 x Pima S 7, Giza 92 x Karshenky and Giza 96 x Suvin were significant desirable SCA effects for some yield traits.…”

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
