Abstract
Fusarium wilt, incited by Fusarium oxysporum Schlechtend.:Fr. f. sp melonis Snyd. & Hans., is a severe disease of muskmelon (Cucumis melo) worldwide.
Races 0, 1, 2, and 1,2 were designated based on the resistance genes that are overcome by variants of the pathogen.
Polygenic recessive genes have been found to confer tolerance to race 1,2 in Piboule genotypes.
Seven doubled-haploid (DH) melon lines, originated from parthenogenesis using irradiated pollen were produced.
Two promising DH lines, were selected for resistance/tolerance to Fusarium wilt following inoculations with race 1,2w.
These two doubled-haploid lines represent a source of resistance/tolerance commercially exploitable either as rootstocks or as lines for F1 constitutions.
