Abstract

The objective

of this study was to determine the incidence and severity of

papaya fruit anthracnose (Colletotrichum gloeosporioides).

The experiment was carried out in Guápiles, Limón, Costa

Rica, between the years 2010 and 2011. Five lines and

four crosses were evaluated in a randomized complete

block design with three replications. Evaluated traits were

incidence and severity of anthracnose, fruit firmness and

total soluble solids content of the pulp. Results suggest

that the crosses have intermediate characteristics to those

of their parent lines for these traits. In the specific case of

anthracnose, evidence also suggests that the resistance to this

disease tends to be inherited in a dominant manner.
