Abstract:
Downy mildew is one of the most common types of destructive foliar disease of cucumber, Oomycete pathogen Pseudoperonospora cubensis is responsible for this in cucumber, moderately resistant Hybrids and open pollinated verities are available, but without the use of fungicides, yield losses are enormous. The development and utilization of resistant cultivars is economically and ecologically considered to be the best approach to control downy mildew. The Wild cucumber (C. sativus var. hardwickii) originated in India and served as a source of resistance to a number of diseases, including downy mildew however, recently it has shown a susceptible reaction. The current research aimed to find the lines that are resistant among the 34 screened lies the 3 USDA accessions PI-330628, PI-250147, and PI-197085 displayed resistance to downy mildew. These lines can be more thoroughly used for resistant lines or hybrid development.
