Blackmold

A mold of ripe fruit, blackmold, is caused by the fungus Alternaria alternata and can lead to severe harvest losses in processing tomatoes (Pearson and Hall 1975). The disease progression begins with dry sunken lesions on the fruit which may extend into fruit cavities. RAPD genotyping of A. alternata identified two major phenetic groups and genetic diversity of the pathogen (Morris et al. 2000). QTLs for blackmold resistance were mapped by Robert et al. (2001) and found on chromosomes 2, 3, 9, and 12.
