Table 9 Clusters containing multiple QTLs from different trait categories (fiber quality, yield or morphological). QTL mapping study involved the RIL population of cross NC05AZ06 × NC11–2091 genotyping with Cotton 63K SNP array. Phenotypic traits were evaluated in the field at Central Crops Research Station, Clayton, NC in years 2016 and 2017
