Distribution of mating types of Phytophthora palmivora
Mating type was determined for 206 isolates of Phytophthora palmivora, 116 were A exponent 2, 80 were A exponent 1, and ten did not form oospores with either test strain. These data were combined with previous records of intraspecific crosses in P. palmivora to give for the first time a world-wide summation of the geographical distribution of the two mating types and of their host relationships. Both types occur in Brazil, Cameroun, Ceylon, Costa Rica, Gabon, Ghana, India, Ivory Coast, Jamaica, Malaya, Mexico, Nigeria, Puerto Rico, Rhodesia, Sarawak, and the United States (Hawaii). New records are included of A exponent 1 and A exponent 2 types in a number of countries
