A major quantitative trait locus (QTL)
for Fusarium oxysporum Fr. f. sp. niveum race 1 resist‑
ance was identified by employing a “selective genotyp‑
ing” approach together with genotyping‑by‑sequencing
technology to identify QTLs and single nucleotide poly‑
morphisms associated with the resistance among closely
related watermelon genotypes.
