The occurrence of sexual compatibility types (mating types) was studied in a set of 59 Bremia lactucae isolates originating from 33 naturally infected and wild populations of Lactuca serriola (prickly lettuce) plants occurring in the Czech Republic, Germany, and France. The isolates were collected in 1997-99 as part of detailed population studies of virulence structure. Both compatibility types (B1 and B2) were recorded.
