Abstract

In 1969, 355 leaf or tuber samples from potatoes suspected of harboring the potato spindle tuber virus were collected from 23 tablestock fields in eastern Canada. By means of Fernow's tomato cross protection test, modified by the use of ribonucleic acid extract as inoculum, 317 samples were shown to be infected, 290 (92%) of these with a mild strain, and 27 (8%) with a severe strain of the virus. Preliminary tests in the greenhouse and field indicate that the mild strain, so named because of symptoms on tomato, is relatively mild in the potato as well.

Resumen

En 1969, 355 muestras de hojas o tubérculos posiblemente infectados con el virus de tubérculos ahusados (PSTV) fueron collectados de 23 campos comerciales en el Este del Canadá. Por media del ensayo de proteción cruzad en tomate de Fernow, modificado con el uso de extracto del ácido ribonucleico como inóculo, 317 muestras fueron probados como infectados, 290 (92%) con la blanda, y 27 (8%) con la cepa virulenta del virus. Ensayos preliminares en el invernadero y campo indican que la cepa blanda, llamado así debido a los sintomas en tomate, es también relativamente blanda en la papa.
