Response of wild Cucumis species to inoculation with Pseudomonas syringae pv. lachrymans

Under controlled inoculation, a set of 49 accessions belonging to 16 wild species and varieties of the genus Cucumis was tested for resistance to Pseudomonas syringae pv. lachrymans. There was no complete resistance to this pathogen in Cucumis accessions, but limited necrotization of leaves was obse...

Description
Summary:Under controlled inoculation, a set of 49 accessions belonging to 16 wild species and varieties of the genus Cucumis was tested for resistance to Pseudomonas syringae pv. lachrymans. There was no complete resistance to this pathogen in Cucumis accessions, but limited necrotization of leaves was observed in four accessions (C. africanus (PI 203974), C. anguria var. longipes (CUC 28/1974), C. melo subsp. conomon Baj-Gua (CUM 238/1974), C. zeyheri (PI 299572)). There were some quantitative differences between Cucumis accessions in disease symptom development.
