BOGANTES-ARIAS, Antonio  and  MORA-NEWCOMER, Eric. Incidencia y severidad de la antracnosis en líneas e híbridos de papaya (Carica papaya). Agron. Mesoam [online]. 2013, vol.24, n.2, pp.411-417. ISSN 2215-3608.

Incidence and severity of anthracnose in breeding lines and crosses of papaya (Carica papaya). 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.

Keywords : Colletotrichum gloeosporioides; postharvest life of papaya fruit; anthracnose resistance in papaya.
