The genus Gossypium provides natural fiber for textile industry worldwide. Genetic improvement in cotton for traits of interest is not up to mark due to scarcity of adequate information about fiber production and quality. Use of DNA markers for overcoming the issues of selection associated with complex traits is the ultimate choice which may lead to initiate breeding by design. Numerous marker-trait associations have been identified for economical traits using linkage analysis in cotton. Currently there is need for developing high-density genetic maps using next-generation sequencing approaches together with genome-wide association studies (GWAS). Efforts have been started in this direction and several QTLs including fiber quality, yield traits, plant architecture, stomatal conductance and verticillium wilt resistance were identified. This chapter narrates genetic diversity, QTL mapping, association mapping and QTLs related to fiber quality traits. The incorporation of various genomic approaches and previously described marker strategies will pave the way for increase in fiber production.

The two cultivated allopolyploid cottons, Gossypium hirsutum and Gossypium barbadense, represent a remarkable example of parallel independent domestication, both involving dramatic morphological transformations under selection from wild perennial plants to annualized row crops. Deep resequencing of 643 newly sampled accessions spanning the wild-to-domesticated continuum of both species, and their allopolyploid relatives, are combined with existing data to resolve species relationships and elucidate multiple aspects of their parallel domestication. It is confirmed that wild G. hirsutum and G. barbadense were initially domesticated in the Yucatan Peninsula and NW South America, respectively, and subsequently spread under domestication over 4000-8000 years to encompass most of the American tropics. A robust phylogenomic analysis of infraspecific relationships in each species is presented, quantify genetic diversity in both, and describe genetic bottlenecks associated with domestication and subsequent diffusion. As these species became sympatric over the last several millennia, pervasive genome-wide bidirectional introgression occurred, often with striking asymmetries involving the two co-resident genomes of these allopolyploids. Diversity scans revealed genomic regions and genes unknowingly targeted during domestication and additional subgenomic asymmetries. These analyses provide a comprehensive depiction of the origin, divergence, and adaptation of cotton, and serve as a rich resource for cotton improvement.

Pima cotton (Gossypium barbadense L.) is grown for its superior fiber quality in four U.S. states and in several other countries. However, there is a lack of information on major and stable quantitative trait loci (QTL) for fiber quality and agronomic traits and abiotic stress tolerance across different environments. In this study, a genetic linkage map based on 403 simple sequence repeat (SSR) markers was developed for the Pima S‐6/89590 intraspecific mapping population consisting of 161 recombinant inbred lines (RILs). Through the evaluation of the RIL population in seven field tests for agronomic traits and fiber quality in the four pima cotton‐growing U.S. states and four greenhouse tests for drought and salinity tolerance, a total of 156 QTL were detected. Eight QTL clusters and four hotspots were further identified, and many of the QTL and their clusters and hotspots were consistent with previous studies that will be useful for marker‐assisted selection. Using a basic local alignment search tool (BLAST) search against the sequenced Pima 3‐79 genome, 26, 16, 32, 14, 127, and 14 candidate genes were predicted for 15 stable QTL on six chromosomes (chromosomes 3, 10, 12, 19, 21, and 24, respectively), for fiber quality traits and abiotic stress tolerance. These genomic regions were rich in genes related to fiber developments and abiotic stress responses. This study provides important information on new and stable QTL across environments for developing superior American pima cotton.
