Reproduction of Globodera rostochiensis on Transformed Roots of Solanum tuberosum cv. Desiree

A. Kumar, J. M. S. Forrest

Abstract


Transformed roots of the susceptible potato Solarium tuberosum L. cv. Desiree were inoculated with second-stage juveniles (J2) of Globodera rostochiensis pathotype Rol. Adult males emerged after 3-4 weeks and matings with females occurred. After 8 weeks gentle pressure on the eggs of maturing females released the J2 which were viable. Because this technique enables the production of vigorously growing roots with numerous laterals, it may be suitable for obtaining a high yield of sterile potato cyst nematodes.
