THE sexual process of the heterothallic fungus, Phytopthora infestans (Mont.) De Bary, in Mexico1,2has long been suspected of being an important source of variation in the pathogenesis of new isolates to resistant varieties of potato2. Although various investigators2–6have reported a low percentage of germination of oospores from controlled crosses in the laboratory, there is little information about the role of sexuality. In some of our experiments as much as 64.0 per cent of the oospores germinated. In this communication, we will briefly describe the variation in pathogenesis and compatibility type of progeny from single germinated oospores. |
