Study-name finding: Wu et al. report whole-genome confirmation of Wilking as a King–Willowleaf hybrid. The paper does not assign seed/pollen direction. The catalog already records King Tangor seed × Willowleaf pollen, consistent as an unordered named pair. Figure 1 uses study code M19; the supplementary accession table was unavailable, so an exact study-accession-to-catalog-clone match is not established.
