摘要：

Several races of Podosphaera xanthii have been described on melon. The Indian melon line '90625' (PI 3 13970) which had already been described as resistant in the USA is a potential Source of resistance for strains recently characterized in France. We have studied the inheritance of resistance in a Recombinant Inbred Line Population between 'Vedrantais' (Susceptible) and '90625' using a leaf disk technique with 10 strains of P. xanthii. Potentially five genes could be present in '90625'. Two independent semi-dominant genes (A and B) are involved in resistance to strains 06Sm10 and S87-7 respectively. Resistance to the other strains seems to be under a digenic control, including A and B or not, with three other recessive genes. Some of these RILs could be used as additional differential lines for the characterization of the races.
