| Abstract: | Summary Guar is reported for the first time as a host of potato virus Y. The virus produced no symptoms, or occasional faint chlorotic spots on inoculated cotyledons and unifoliate leaves. No symptoms were observed on new growth, but the virus was consistently recovered from these leaves by back-inoculation to tobacco. Neither potato virus X nor cucumber mosaic virus infected guar. |
