An Upland cotton MAGIC population was developed through random mating of 11 diverse cultivars for five generations. In this study, fiber quality data from four environments and 6071 SNP markers generated via GBS, along with 223 microsatellite markers from 547 recombinant inbred lines (RILs) of the MAGIC population, were used to conduct a genome-wide association study (GWAS). By employing a mixed linear model, GWAS enabled us to identify markers significantly associated with fiber quantitative trait loci (QTL). (Islam MS et al.
