dc.description.abstractThe mating types of isolates of Phytophthora palmivora, Phytophthora capsici and Phytophthm citrophthora causing black pod disease of cocoa were determined by pairing them with known A, and A, mating types of P. palmivora, P, capsici and P. meadii. Isolates of P. palmivora and P. capsici produced cospores when paired intra- and inter-specifically with either A, and A2 mating types of P. palmivora, P. capsici and P. mead whereas the isolates of P. citrophthora did not produce oospores. Both A, and A2 mating types were found among the isolates of P. palmivora and P. capsici. A, mating type was predominant in P. palmivora and A, in P. capsici. A2 mating types of P. palmivora was predominant in all the districts of Kerala and Karnataka states. Both A, and Aj mating types of P. palmivora and A; mating types of P. capsici were found in certain localities of Kerala slate from where P. citrophthora isolates were collected. The occurrence of both mating types of different species in same locality reveals the possibility of intra- and inter-specific hybridization in nature and formation of new strains. Tkis is the first report of occurrence of mating types of Phytophthora species causing black pod disease of cocoa in India.en_US
