Inheritance of resistance to downy mildew in a gynoecious muskmelon

The gynoecious, downy mildew-susceptible Cucumis melo W1998 was stabilized for gynoecity and crossed with C. melo PI 124111F, a monoecious breeding line resistant to pathotype 3 of Pseudoperonospora cubensis. F 1 plants (all monoecious) were moderately resistant to downy mildew (reation types 22 and 23). F 2 plants(1/16 gynoecious) segregated I susceptible(reaction type 11): 14 moderately resistant(reaction types 12, 13, 22, 23, 24, and 33): 1 resistant (reaction types 33 and 34)
