Mango wilt: XV. Varietal resistance against two isolates of ceratocystis fimbriata

The objective of this paper is the resistance evaluation of 15 mango varieties in relation to two isolates of the fungi Ceratocystis fimbriata Ell. & Halst.: the IAC FITO 4905 which is very pathogenic to the variety Jasmim and the IAC FITO 334-1 which is not patogenic to this variety. Field inoculations were made about 40 cm from the branch top, using eight years old trees and a complete block design with subdivided plots, being variety the main plot and the fungi isolates the subplots. The varieties São Quirino, Irwin, Edwards and Van Dyke were resistant and 'IAC 100 Bourbon' moderately resistant, against the two isolates whereas Glenn, Joe Welch, Zill and Haden were susceptible. The variety Kent behaved like 'Jasmim' being resistant to the isolate IAC FITO 334-1 and susceptible to IAC FITO 4905, and it may be used like 'Jasmim' for discrimination of these isolates.
