Black pepper (Piper nigrum L.) is famed as ‘King of Spices’. Indian monopoly in the production of black pepper is now constrained due to various diseases. In the present study an evaluation of different endogenous and released varieties was carried out for their resistance against foot rot fungi, Phytophthora capsici through in vitro screening. Thirty two healthy samples were collected from Malappuram, Kozhikode and Palakkad districts of Kerala, India. The pathogen was isolated from diseased black pepper leaves using carrot agar medium supplemented with Pimaricin-Vancomycin- Penta chloro Nitro Benzene- Hymexazol medium. Pure culture discs collected the culture plated were inoculated on to the lower sides of pin pricked or non pinpricked immature black pepper leaves. Upon regular observation, cultivar Panniyur showed more resistance and Karimunda showed the least against the pathogen.
