Abstract : The malformation of mango caused by the fungus Fusarium subglutinans is probably one of the diseases that causes more damages in the mangoes production in Brazil and other producer countries. This fungus was isolated from a Tommy Atkins plant in Sao Paulo, Brazil with advanced symptoms of malformation, purified and prepared to be inoculated in 15 cultivars of national and imported mangoes. Initially, 10 cultivars had been inoculated in July 2000: Bourbon IAC - 100, Coração de Boi, Keitt, Parvin, Primor de Amoreira, Sensation, Smith, Surpresa, Tommy Atkins and Van Dyke. The second group was inoculated in December 2000, on the cultivars: Adams, Bhadauran, Palmer, Princesa and Zill, and the inoculation were repeated with others cultivars: Primor de Amoreira, Sensation and Tommy Atkins, with the purpose of comparing the two different times of inoculation. Throughout the data collected at the different times, after 11 months of evaluation, the analysis with Z mean test was done to compare the averages of unhealthy plants from inoculated cultivars. The cultivars Bhadauran, Palmer, Parvin, Sensation, Surpresa, Van Dyke and Zill present smaller percentage of plants with malformation symptoms or smaller progression of symptoms in relation to the other inoculated cultivars, under protected environmental conditions, where the assays were carried out.
