Abstract
The present inVestlgation was undertaken to characterize a WMV-like
virus, which was isolated from Eskandarani squash (Cucurbita pepo L.) grown in Minya, and for which the provis¬ional name of Watermelon mosaic virus-Egypt(WMV-E) is proposed
The experimental work could be summerlzed as follows;
I) The host-range studies comprised 87 test plants represent¬ing 37 plant specles and 7 families. Of these, 44 host plants
(30 from the Cucurbitace_e, 9 from the Solanace_e, 2 from the Leguminosae, 2 from the Chenopodiaceae, and one from the Amaranthaceae) were included in tests with WMV-l, WMV-2 and WMV-E, for comparative study of host range and symptomatology.the other 43 test plants (representing 23 plant species and 6 fa¬milles) were tested for WMV-E only.
The following 28 cucurbits (out of the 3u tested ones)rev¬ealed as hosts of each of WMV-l, WMV-2 and WMV-E.
