Upland cotton (Gossypium hirsutum L., 2n= 52, AADD) is an allotetraploid, therefore the
discovery of single nucleotide polymorphism (SNP) markers is difficult. The recent …

Background Tetraploid cotton contains two sets of homologous chromosomes, the At-and Dt-
subgenomes. Consequently, many markers in cotton were mapped to multiple positions …

A narrow germplasm base and a complex allotetraploid genome have made the discovery of
single nucleotide polymorphism (SNP) markers difficult in cotton (Gossypium hirsutum). To …

The presence of two closely related subgenomes in the allotetraploid Upland cotton,
combined with a narrow genetic base of the cultivated varieties, has hindered the …

Cotton is an important fiber crop worldwide. Improved fiber quality is a driving force for cotton
genetic studies and breeding. A BC 1 population containing 115 individuals from a cross …

Abstract Background Cotton (Gossypium spp.), as the world's most utilized textile fibre
source, is an important, economically valuable crop worldwide. Understanding the genomic …

Upland cotton (Gossypium hirsutum L.) has a narrow germplasm base, which constrains
marker development and hampers intraspecific breeding. A pressing need exists for high …

Background SNPs are the most abundant polymorphism type, and have been explored in
many crop genomic studies, including rice and maize. SNP discovery in allotetraploid cotton …

Background Improving fiber quality and yield are the primary research objectives in cotton
breeding for enhancing the economic viability and sustainability of Upland cotton …

Varietal single nucleotide polymorphisms (SNPs) are the differences within one of the two
subgenomes between different tetraploid cotton varieties and have not been practically used …
