An Israeli breeding line, BIZ, resistant to all four races of Fusarium oxysporum f.sp. melonis (FOM), has been characterized regarding its response to FOM race 1.2. The infection process of a FOM 1.2 strain that expresses the GFP reporter protein was monitored, suggesting the timing and sites in which fungal progression differs between a resistant and a susceptible genotype. A mapping population derived from the cross PI 414723 and BIZ was used to construct a linkage map with ~90 traits and markers, and QTL analysis of FOM1.2 resistance was initiated. Other traits such as flesh color and rind netting were mapped as well. A major recessive QTL for FOM1.2 resistance was located in linkage group 2, near a major locus controlling net development.
