Genome-Wide Association Study (GWAS) Reveals Significant SNP Marker Detected for Fusarium Wilt Disease Resistance in Louisiana Sweetpotato Germplasm
diverse lines over two years. The sweetpotato accessions were genotyped using the 3K DArTag® marker panel. GWAS identified one marker that was significantly associated with Fusarium wilt resistance, providing putative target for future validation and potential use in marker-assisted selection (MAS). These findings offer valuable resources for MAS and lay the groundwork for developing Fusarium wilt-resistant sweetpotato cultivars.
