Abstract
An in vitro inoculation method for the identification of physiologic races of Phytophthora fragariae var. fragariae was evaluated.
Sixteen strawberry cultivars were micropropagated through meristem tip culture.
Single shoots were rooted on a medium with IBA and activated charcoal.
The rooted shoots were inoculated in vitro with a pure culture zoospore suspension of five German isolates of P. fragariae var. fragariae. For estimation of disease symptoms different parameters were taken including measuring the length of root discolouration, the length of the red stele and the number of oospores in root segments.
The value of these parameters for diseases assessment is discussed.
Three different races could be identified using the cultivars Senga Sengana, Saladin, Climax and Yaquina B, this being in accordance with former results achieved by using an in vivo inoculation method.
