Professor, Department of Horticulture, Professor, Department of Plant Pathology, and Technician, Department of Horticulture, Alabama Agricultural Experiment Station, Auburn University 36849. Plant Dis. 76:251-252. Accepted for publication 1 October 1991. Copyright 1992 The American Phytopathological Society. DOI: 10.1094/PD-76-0251. Of 153 plant introductions (PI), breeding lines, and commercial cultivars tested by mechanical inoculations in the greenhouse, only PI 482261-1, Egun, PI 494528, PI 386026, and PI 386025 showed any resistance to the Florida strain of zucchini yellow mosaic virus. PI 482261-1 and Egun are Citrullus lanatus, the others are citron types (Citrullus colocynthis). This is the first report of resistance in PI 386026, PI 386025, and the cultivar Egun. |
