Abstract An investigation of how the common or Scottish
strain of the pollen transmitted
Raspberry bushy dwarf virus
(RBDV) became established in New Zealand indicates that `Canby', a red
raspberry cultivar (
Rubus idaeus L.), introduced in 1965 and released
for field evaluation in 1966, would be the most likely source. At the time of
its introduction, all plants of `Canby' grown in other countries are thought to
have been infected with RBDV, and this same infection is likely to have been
present in plants imported into New Zealand. `Canby' was subsequently found to
be infected with RBDV in New Zealand field plantings and commonly showed leaf
yellows wherever it was grown. Testing of a number of
Rubus cultivars
either recently introduced from other countries, or obtained from the New
Zealand
Rubus breeding programme, showed four (`Glen Rosa, `Lewis',
`Malahat', and `Summit') to be RBDV infected. Graft inoculations with the New
Zealand source of RBDV to other cultivars showed three of the imports (`Glen
Ample', `Qualicum', and Tulameen') and one of the locally bred selections (`HR
104') to be infectible with the common strain of RBDV.
