Interspecific hybridization is an important evolutionary process contributing to adaptation and speciation. During the last decade, advances in the molecular taxonomy techniques have led to increasing the number of descriptors interspecific hybrids in the genus Phytophthora. In Phytophthora hybrids, inheriting and recombining genes from both parents may result in increased aggressiveness and broader host range compared with either parent. Some Phytophthora natural hybrids have also been

Consequently, identification, pathogenicity and host range tests of these hybrids as well as preventing the formation of new hybrids before experiencing large economic losses are recommended for management of plant diseases caused by this fungal-like organisms.
