In order to enhance marker-assisted selection for oil spill remediation, this work found quantitative trait loci (QTL) linked to kenaf's oil sorption capacity. To create F1 and then F2 populations for linkage and QTL study, two opposing parental accessions were crossed. The F2 progeny's oil sorption capacity was assessed phenotypically and utilized for mapping. A modified CTAB technique was used to extract genomic DNA, and 96 samples were genotyped using DArTSeq technology. JoinMap 4.1 was used for linkage mapping, while MapQTL was used for QTL finding. With an average marker interval of 1.39 cM, 18 linkage groups were created, spanning a total map length of 1888.40 cM. Three important and eight potential QTL governing oil sorption ability were identified by the research.
