Two inbred lines and five F1 hybrids of cucumber resistant to downy mildew were evaluated for resistance in growth chambers and the field. Best-performing plants were selfed and S4 plants were crossed with a high-yielding, parthenocarpic, susceptible partner. Resistance in J-13, a derivative of Wisconsin 2843, was found to be controlled by incompletely dominant gene(s). Resistance was expressed as small, chlorotic, water-soaked lesions with negligible sporulation of the fungus. No breakdown of this resistance was observed at 12°C.
