Abstract

Abstract The level of resistance against Phytophthora pod rot disease was assessed among twenty-four exotic accessions of cocoa by non pricking method of pod inoculation. In the non-pricking method, eleven genotypes were grouped under highly resistant category. Binomial logistic regression model revealed that phenes like polyphenol content, wax, husk polyphenol and calcium content had a negative influence with Phytophthora Resistance. From the present investigation, it was found accessions NA 33, NA 702 and PA 70 showed maximum resistance to disease with high yield potential and those could be utilized for further genetic improvement programmes in cocoa.
