The experiment was conducted using a randomized complete block design with three replications at Shah Abdul Latif Experimental Farm, Sindh Agriculture University, Tandojam. Employing a line × tester mating design in upland cotton (Gossypium hirutum L.), twenty-one cross combinations were obtained from seven females and three males. F1 and F2 generations, along with their parents, were sown in a randomized complete block design with three replications during 2012-13 and 2013-14. Studied traits included lint yield (g) per plant, G.O.T (%), staple length (mm), fiber fineness (mic.value), and fiber strength (g/tex). Throughout the growing period, recommended cultural practices were followed. Analysis of variance revealed high significance for genotypes, parents, crosses, and their interactions (P×C) for all traits. In the F1 generation, lint yield and staple length under line × tester (L×T) were highly significant. For the F2 generation, genotypes, parents, crosses, and P×C were highly significant for all traits except G.O.T%, where lines, testers, and L×T were highly significant for all traits except G.O.T%. Cross VH-292 × VH-291 excelled in lint yield per plant, while CRIS-342 × IR-3701 demonstrated superior fiber fineness and strength. VH-292 × VH-291 also displayed higher lint yield per plant, while CRIS-342 × FH-113 exhibited longer staple length with increased fiber fineness. Significant mean squares for genotypes (parents, crosses, and parents × crosses) indicate the data's utility for assessing parental performance, hybrid evaluation, heterotic effects, and inbreeding depression.

“…Imran et al (2012), Kumar et al (2013), Simon et al (2013) and Raza et al (2013) came to the same conclusion. However, Memon et al (2016) found that the gca variance was larger than that of sca, and the rank order for gca's of the parents differed from F1 to F2 …”

“…Diallel analysis, as developed by Hayman (1954 and1958), Jinks (1956) and Jinks & Hayman (1953), provides full information to identify superior parents and crosses for different traits. Several researchers (Luckett, 1989;Khan et al 1995;Iqbal & Khan, 1996;Esmail et al, 1999;Mukhtar et al 2000;Nadeem & Azhar, 2004;Basal & Turgut, 2005;Mohamed et al 2009;Imran et al 2012;Kumar et al 2013;Raza et al 2013;Simon et al 2013;Soomro et al 2006;Waqar et al 2015 andMemon et al, 2016) pointed to the importance of genetic studies of the materials before selecting the desirable plant. Azhar & Khan (2005), Abbas et al (2008), Abd El-Bary et al (2008), Zangi et al (2009), Palv (2009 and Darweesh (2010) reported that GCA effects were highly significant for number of bolls, seed cotton yield and lint percentage.…”

THIS RESEARCH was conducted to study the effects of late planting on the performance of Egyptian cotton sensitivity to environment, and gene actions that controlling seed cotton yield/plant (SCY/P) and related traits. Half diallel crosses of eight Egyptian cotton varieties were evaluated under early and late plantings. The analysis of variance indicated significant (p ≤ 0.01) differences among entries (parents and crosses) for most traits. The reduction percentin seed SCY/P caused by the stress of late planting was 17.98 and 18.25 percent for the parents and hybrids; respectively. Stress susceptibility index indicated that five parents were tolerant for SCY/P to late planting. Fifteen out of the 28 hybrids showed tolerance in SCY/P to late planting. The diallel analysis of variance indicated that both additive and dominance effects of genes were involved in the inheritance of all traits. Generally, the regression coefficient "b Wr/Vr " and the graphical analysis revealed that the inheritance of seed cotton yield/plant controlled by additive, dominance and epistatic effects of genes. The results of boll weight under the stress of late planting suggested the presence of additive, dominance and epistatic genes interaction. The genetic analysis of number of seeds/boll under late planting indicated no significance of the additive effects of genes "a item", however, the dominance item "b" was significant (p≤ 0.01). The non-additive effects of genes were reflected in the departure of narrow from broad sense heritability. Therefore, pedigree and recurrent selection breeding methods could be effective in isolating lines adapted to late planting.

“…Additive gene action with higher GCA estimates and non-additive gene action with higher SCA estimates have potential role in the identification and selection of superior lines. 2 Due to the importance and demand of cotton it is necessary to develop cotton varieties with high yield potential and fiber qualities. For this purpose it is necessarily to study the inheritance pattern of genes for various yield and fiber quality contributing traits which are helpful for the genetic improvement of available germplasm.…”
