Description

The objectiveof this study was to determine the incidence and severity ofpapaya fruit anthracnose (Colletotrichum gloeosporioides).The experiment was carried out in Guápiles, Limón, CostaRica, between the years 2010 and 2011. Five lines andfour crosses were evaluated in a randomized completeblock design with three replications. Evaluated traits wereincidence and severity of anthracnose, fruit firmness andtotal soluble solids content of the pulp. Results suggestthat the crosses have intermediate characteristics to thoseof their parent lines for these traits. In the specific case ofanthracnose, evidence also suggests that the resistance to thisdisease tends to be inherited in a dominant manner.
El objetivo de esteestudio fue determinar la incidencia y severidad de la antracnosis(Colletotrichum gloeosporioides), en frutas de papaya.El experimento se realizó en Guápiles, Limón, Costa Rica,entre los años 2010 y 2011. Se sembraron cinco líneas ycuatro híbridos bajo un diseño de bloques completos al azarcon tres repeticiones. Se evaluó la incidencia y severidadde la antracnosis, así como la firmeza y los sólidos solubles(grados Brix) de la fruta. Los híbridos presentaron característicasintermedias a los padres para las característicasevaluadas. En la antracnosis de fruta, la resistencia tiende aser dominante para el material evaluado.
