Abstract:
Fifty genotypes of black pepper including five varieties viz., Panniyur 1, Panniyur 5, Vijay, IISR Malabar Excel and Pornami were screened against Phytophthora foot rot disease by artificial inoculation of culture disc of Phytophthora capsici in detached leaves. None of the genotypes were found immune to P. capsici. Black pepper variety IISR Malabar Excel, cultivars such as ICP 102, Kulathurpuzha, Mundi, Padarppan, Vellanamban 1 and Veluthanamban 5 recorded lowest lesion development after 48, 72 and 96 hours of inoculation with P. capsici. Cultivars, ICP 102, Vellanamban 1, Angamaly and Arakkalamunda 4 came in the lowest classes of disease incidence. Among the different genotypes screened against foot rot disease, ICP 102 was found to be the most tolerant followed by Vellanamban 1, which showed lowest lesion development and came in the lowest classes of disease incidence.
