| dc.description.abstract | The study was carried out to screen one hundred and five cocoa types obtained from major cocoa growing areas of various countries and maintained at Cadbury-MU Cooperative Cocoa Research Project, College of Horticulture, Vellanlkkara, for resistance1 tolerance to P. palmivora. For screening, detached pods of the same maturity were artlficlally Inoculated wlth mycelial disc of P. palmivora and were Incubated at 25-250C in poly bags to ensure! high humidity. The lesion area of infected pod was recorded at four and seven days after inoculation. Out of the 105 cocoa types screened, only one type, vlz., GVI-14 (C 78) showed moderate resistance having the least pod area infection. Thirty three types were found susceptible. Among them, GVI-96 (Landas 40), GVI-26 (p,Xp7), GVI-60 (Ma 33) and GVI-53 (MOQ 413) showed comparatively lower disease ratings. Remaining 71 cocoa types were highly susceptible wlth types GVI 100 (Landas 50), GVI-131 (Local), GVI-135 (Local) and GVI-172 (AMAZ 3-2) recording hundred per cent Infection. | en_US |
