RAGAZZO-SANCHEZ, Juan Arturo et al. Molecular identification of the fungus causing postharvest rot in jackfruit. Rev. Mex. Mic [online]. 2011, vol.34, pp.9-15. ISSN 0187-3180.

Jackfruit (Artocarpus heterophyllus) belonging to the family Moraceae, is a popular tropical fruit originated from India and Malasia and is now widely grown in San Blas, Nayarit, Mexico. Jackfruit has a short shelf life (2-3 days after harvest), mostly because of losses due to postharvest diseases caused by pathogenic fungi. These fungi have not been identified in jackfruit from Nayarit. The aim of this research is to identify the fungi that cause diseases in jackfruit in order to develop new post-harvest practices for the future. Five fungi, corresponding to the genus Aspergillus and Penicillium were isolated from deteriorated jackfruit. The pathogenicity test was positive only for Aspergillus sp. which after PCR analysis was identified as Aspergillus niger ATCC16888.

Keywords : phytopathogenic fungi; Artocarpus heterophyllus; Aspergillus niger; Penicillium.
