The estimation of heritability, genetic advance and direct effect yield attributing components on seed cotton have been used to develop indirect selection criteria. For this purpose, seven parents their F2 populations were evaluated for the identification superior be transferred further generations. Claudia x AGC-208, AGC-85 MD combinations fiber quality. highest heritability recorded in boll n...

Cotton plants engineered for resistance to the herbicides, glyphosate or glufosinate have made a considerable impact on the production of the crop worldwide. In this work, embryogenic cell cultures derived from Gossypium hirsutum L. cv Coker 312 hypocotyl callus were transformed via Agrobacterium tumefaciens with the rice cytochrome P450 gene, CYP81A6 (bel). In rice, bel has been shown to confe...

Cotton is a potential and excellent candidate to balance both agricultural production remediation of mercury-contained soil, as its main fiber hardly involves into food chains. However, in cotton, there known rarely about the tolerance response mercury (Hg) environments. In this study, biochemical physiological damages, Hg concentrations (0, 1, 10, 50 100 µM), were investigated upland cotton se...

Trichogramma Westwood (Hymenoptera: Trichogrammatidae) cause high mortality rates in the potentially resistant pest species, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), and are considered integral to the resistance management plan for Bacillus thuringiensis transgenic cotton, Gossypium hirsutum L., production in the Ord River Irrigation Area (ORIA), WesternAustralia.Measured as perc...

The presence of promoter(s) of ethylene biosynthesis in young cotton (Gossypium hirsutum L.) fruits (bolls) was demonstrated by injection of an aqueous extract from bolls into other bolls and measurement of a 3-fold increase in rate of ethylene evolution. Injection of methionine did not affect rate of ethylene production, indicating that the promoter extracted from bolls was not methionine. Inj...

A full-length cDNA, MIC-3, has been identified from a lambda ZAPII cDNA library constructed from the mRNA of nematode-resistant cotton (Gossypium hirsutum L.) roots after infection with root-knot nematode (Meloidogyne incognita). The putative open reading frame of MIC-3 encoded a protein of 141 amino acids with a calculated molecular mass of 15.3 kDa. Seven alternative polyadenylation sites hav...

Cotton fiber is multigenic trait controlled by number of genes. Previous studies suggest that one of these genes may be responsible for switching cotton fiber growth on and off to influence the fiber quality produced from a cotton seed. In the present study, the Gossypium hirsutum GhEXPA8 fiber expansin gene was introduced into local cotton variety NIAB 846 by using an Agrobacterium-mediated ge...
