Technical Abstract: A cooperative project was conducted to determine the genetic variability among populations of the Ustilago scitaminea, the pathogen of sugarcane smut, from different sugarcane growing regions of the world. A common set of 11 sugarcane cultivars with different reported reactions to smut was distributed to participating countries to determine their susceptibility or resistance to indigenous popluations of U. scitaminea. Each cultivar was vegetatively propagated from a single bud and shipped to the participants at 14 locations in 10 countries. A protocol that outlined specific procedures for planting, inoculating, and evaluating results was followed at each location. The reaction of the common set of cultivars to the local populations of smut was similar at all locations except Taiwan. A cultivar that was highly susceptible at other locations was resistant to smut in Taiwan suggesting the existence of a different race of U. scitaminea at that location.
