Inheritance of Podosphaera xanthii resistance in melo "90625"

, 2008
Several races of Podosphaera xanthii have been described on melon. The Indian melon line ‘90625’ (PI 313970) 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 ‘Védrantais’
