“…It is recommended for cotton breeders to exploit these characters pedigree selection may also be suitable. Same conclusions were drawn in the previous studies for one or other fiber quality trait (Esmail, 2007;Srinivasan et al, 2013;Refaey and Razek, 2013). Genetic variance of almost all the fiber traits was equal to that of phenotypic variance coupled with higher estimates of genetic gain and heritability (Table 5) so, selection could be rewarding in cotton fiber quality improvement program.…”

“…Under water stressed conditions, inheritance of fiber traits involved additive along with epistatic type of gene action (Ahmad et al, 2009;Shakoor et al, 2010) while Esmail (2007), Srinivasan et al (2013), and Refaey and Razek (2013) found both additive and non-additive type of gene action but the magnitude of additive was higher than non-additive genes. Present research concluded that fiber length is found to be controlled by additive, dominant and epistatic kind of gene action (Table 3).…”

Genetic effects on fiber quality parameters in six basic populations (P1, P2, F1, F2, BC1 and BC2) of crosses viz. TARZAN-1× CIM-602 and A-555×FH-114 were investigated through GMA. The outcomes of the current study envisaged that additive and dominant alongside non-allelic interactions assumed a significant role for the attributes like fiber length and fiber maturity in both crosses, however, additive genetic actions [d] were observed to be imperative for fiber uniformity, fineness and bundle strength. Epistatic gene interactions were present almost in all the quality traits in one or other cross, whereas linkage was prominently observed in bundle strength and fineness. All the fiber traits showed high genetic variance and genetic advance except fiber length where genetic gain was relatively low under normal and water stressed conditions. Inverse indication of [h] and [i] anticipated duplicate genes in the legacy of fiber fineness and length that will bring plant breeders in trouble during selection. Hence, heterosis breeding would be a better choice because complementary gene interaction was absent in all quality traits.

“…Jagtap [8] stated that when additive effects are larger than non-additive ones, selection in early generation would be effective, while if the nonadditive portions are larger than additive one, the improvement of the character need intensive selection through later generation. The evidence of non-allelic interaction was reported by Refaey and Razek [10] for fibre traits.…”

“…Patil et al (2005) reported inadequacy of the additive-dominance model and the presence of non-allelic gene interaction. The three types of epistasis differed from cross to cross (Darweesh, 2006;Abd-El-Haleem et al, 2010 andEl-Refaey et al, 2013). Laxman et al (2003) revealed that the components of genetic variance indicated predominance of dominance × dominance type of epistatic interaction followed by additive × dominance, besides equally important role of dominance, additive and additive × additive type of gene actions were found.…”

T HE PRESENT work was conducted to study the effects of late planting on the performance of Egyptian cottons, sensitivity to environments and gene action controlled earliness, lint yield/plant, lint % and lint index. A half diallel crosses of eight Egyptian cottons varieties were evaluated under normal and late plantings. The reduction % in lint yield/plant was 23.21 and 23.87% for the parents and F 1 hybrids; respectively. The results of stress susceptibility index of LY/P indicated that six parents were tolerant for LY/P to late planting. Sixteen out of the 28 hybrids showed tolerance in LY/P to late planting. The diallel analysis revealed significant (p ≤ 0.01) items; ''a'' and ''b'', indicating that both additive and dominance effects of genes were involved in the inheritance of the five studied traits. The genetic parameter indicating that ''H 1 '' tended to be more than the additive parameter ''D'' under late planting. The regression analysis of Wr/Vr indicated the presence of non-allelic interaction in the inheritance of lint yield/plant under late planting. However, the additive-dominance model was adequate in the inheritance of days to first flower under normal and late plantings. The ''b 2' '' item and KD/KR indicated unequal distribution of dominance and recessive genes in the parents for all traits. The nonadditive effects of genes were reflected in the departure of narrow form broad sense heritability. Therefore, pedigree and recurrent selection breeding methods could be effective to isolate lines adapted to late planting.
