Abstract
The attraction of zoospores of Phytophthora cinnamomi Rands to roots of three cultivars of rabbiteye blueberry (Vaccinium ashei Reade), two species hybrid cultivars of highbush blueberry, and one tetraploid species hybrid selection (US 109) was compared. Zoospores were attracted to the roots of all plants tested. Roots of highbush cultivars ‘Bluetta’ and ‘Patriot’ attracted more zoospores than the rabbiteye cultivars. The number of zoospores attracted to roots of US 109 was greater than the number attracted to the three rabbiteye cultivars, but less than the highbush cultivars. Increased zoospore attraction appeared to be related to root rot susceptibility in blueberries.
