Abstract

Isolates of Phytophthora infestans of A1 mating type from central Mexico and Wales, when mated to a range of A2 isolates from Russian and Mexico, produced a proportion of abnormal oogonia with several oospheres. Similar oogonia were observed in self- fertile lines resulting from treatment of a Russian A1 isolate with a chemical mutagen followed by the fungicide, metalaxyl.
