Gene Flow between Gossypium hirsutum L. and Gossypium barbadense L. is Asymmetric
As both Pima cotton (Gossypium barbadense L.) and Acala (Upland; G. hirsutum L.) are grown in the southwestern United States, understanding gene fl ow within and among these species is important to maintain genetic purity. In small scale and commercial fi elds, gene fl ow decreased exponentially from 1.44% at 1 m to less than 0.50% at 10 m in Acala cotton. Corresponding values for Pima cotton w...
متن کاملEstimation of genetic parameters for quantitative and qualitative traits in cotton cultivars (Gossypium hirsutum L. & Gossypium barbadense L.) and new scaling test of additive– dominance model
A complete diallel cross of nine cotton genotypes (Gossypium hirsutum L. & Gossypium barbadense L.) viz Delinter, Sindose-80, Omoumi, Bulgare-539, Termez-14, Red leaf (Native species), B-557, Brown fiber and Siokra-324 having diverse genetic origins was conducted over two years to determine the potential for the improvement of yield, its components, oil and fiber qual...
متن کاملInfraspecific DNA methylation polymorphism in cotton (Gossypium hirsutum L.).
Cytosine methylation is important in the epigenetic regulation of gene expression and development in plants and has been implicated in silencing duplicate genes after polyploid formation in several plant groups. Relatively little information exists, however, on levels and patterns of methylation polymorphism (MP) at homologous loci within species. Here we explored the levels and patterns of met...
متن کاملEffect of Nitrogen on Seed Cotton Yield and Fiber Qualities of Cotton (gossypium Hirsutum L.) Cultivars
Seed cotton yield and fiber qualities may be significantly altered by a number of agronomic practices. The present study investigates the effect of nitrogen levels on cotton cultivar's seed cotton yield and fiber quality traits. Three cotton cultivars (NIAB-111, CIM496 and FH901) were tested against four nitrogen levels (0, 60, 120 and 180 kg ha) to check reliability, the highest yielding and g...
متن کاملGenetic and phenotypic effects of chromosome segments introgressed from Gossypium barbadense into Gossypium hirsutum
MBI9915 is an introgression cotton line with excellent fiber quality. It was obtained by advanced backcrossing and continuous inbreeding from an interspecific cross between the upland cotton (Gossypium hirsutum) cultivar CCRI36 as the recurrent parent and the sea island cotton (G. barbadense) cultivar Hai1, as the donor parent. To study the genetic effects of the introgressed chromosome segment...
