Cucumber (Cucumis sativus) Breeding Line with Young Fruit Resistance to Infection by Phytophthora capsici

cuccap

Cucumber (Cucumis sativus) production in the eastern and midwestern United States is subject to severe losses due to fruit rot caused by the soilborne oomycete pathogen, Phytophthora capsici. P. capsici preferentially infects cucumber fruits, especially young fruit, while leaves and vines remain healthy. Disease is manifested by extensive mycelial growth, sporulation, fruit rot, and tissue collapse. There are currently no commercial cucumber cultivars with resistance to this disease.
