Abstract

Foliage BLIGHT symptoms have been observed on cucunber (Cucumis sativus), cantaloupe (Cucumis melo) and squash (Cucurbita pepo) plants in Varamin since 1996. Symptoms consist of marginal mecrosis surrounded by chlorotic halos that expand as V-shaped blotches along and between the major leaf veins. The BLIGHT has been severe during and following periods of wet and rainy weather when the day-time temperature averaged 27-30°C. A rod-shaped, Gram-negative, oxidase positive, fluorescent Pseudomonas was consistently isolated from the diseased leaves on medium B of King.On the basis of the phenotypic features, the strains were identified as Pseudomonas marginalis pv. marginalis. The electrophoretic profiles of cell proteins of the strains were similar to each other and to a reference strain of Pseudomonas marginalia pv. Marginalis ICMP 3553. Pathogenecity of the strains was confined on CUCUMBER (cv. Soltan and line RS- 410332) under greenhouse conditions, and strains were isolated from the inoculated plants. To evaluate the resistance of CUCUMBER cultivars to the pathogen, an experiment using 77 cultivars and lines was performed under greenhouse conditions (22-30°C). The majority of CUCUMBER cultivars and lines were rated as susceptible and a few rated tolerant to P. m. pv. marginalis. cultivars and lines Kozakloo, GH4,.KC 361106, KC 361065, TN 94162, TN 94139, TN 94190 and Super shoal appeared to be tolerant.
