Virus Studies with Cucurbita foetidissima
Cucurbit Genetics Cooperative Report 4:41-42 (article 22) 1981 M. E. Rosemeyer and W. P. Bemis University of Arizona, Tucson, AZ 85721 Two isometric viruses have been isolated from field-grown buffalo gourd (bg), Cucurbita foetidissima. Host range studies, electron microscopy, and serology have been used to identify these viruses as squash mosaic virus (SqMV) and a […]
