Interpretive Summary:

Technical Abstract: Genetic maps are available for most crop species. The immediate application of a map is to localize genes of agronomic importance such as disease resistance. We have created a genetic map of melon (Cucumis melo L.) using over 200 AFLP (Amplified Fragment Length Polymorphims) and other markers. Additional and mapped markers were used to localize Fom-2, a gene conferring resistance to Fusarium wilt of melon caused by race 1 of Fusarium oxysporum f.sp. melonis. A previously identified RAPD marker was found to cosegregate and two AFLP markers flank the gene. These markers are being converted to codominant PCR-based markers for marker-assisted selection (MAS).
