Abstract: Fusarium wilt caused by Fusarium oxysporum f.sp. melonis (FOM) is the most damaging disease of muskmelon worldwide. Race 1,2 is the most aggressive race among the four known races of FOM. This race is the most widespread in the Italian melon growing areas. Its spread has become a problem for melon growing, so that the use of genotypes with resistance to multiple races of the pathogen represents the major objective of melon breeding programs. No genes have been identified in muskmelon that confer high levels of resistance to race 1,2. However, polygenic recessive genes have been found in Piboule genotypes. Until recently, only a few genotypes tolerant to race 1,2 were available commercially. These hybrids are mainly used as rootstocks. An efficient method for testing the level of resistance, using a virulent isolate of FOM race 1,2, isolated from an intensive melon-cultivated area, was developed allowing the screening of different germplasm sources. Promising results were obtained with the variety inodourus and typical southern Italian populations were selected for resistance to race 1,2. These genotypes represent a potentially valuable source of resistance that can be exploited commercially using them either as rootstocks or for F1 hybrid production.
