Cultivars behavior of mango (Mangifera indica L.) in relation to malformation

The malformation of mango caused by the fungus Fusarium subglutinans Wollenweb & Reinking 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 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, Coracao 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 I I months of evaluation, the analysis with Z mean test was made to compare the averages of unhealthy plants from inoculated cultivars. It can be concluded with the results obtained that 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.
