ABSTRACT=Gossypium hirsutum L. is the most important tetraploid species cultivated over 33 million acres worldwide. The precise information about candidate genes involved in complex quantitative traits is a great hindrance to fiber quality improvement. As a result, the overall genetic gain is low in traditional phenotypic selection. Recent molecular interventions and advancements in genome sequencing have led to the development of high-throughput molecular markers, quantitative trait loci (QTL) fine mapping, and single nucleotide polymorphisms (SNPs) with genetic identification have resolved the existing bottlenecks in trait-specific breeding. This review demonstrates the significance of chromosomes 3, 7, 9, 11, and 12 of sub-genomes A and D carrying candidate genes for fiber quality. However, chromosome 7 carrying SNPs for stable and potent QTLs related to fiber quality provides great insights for fiber quality targeted research. This information can be validated by marker-assisted selection (MAS) and transgene in Arabidopsis and subsequently in cotton.
