The charcoal root disease caused by Macrophomina phaseolina (Tassi) Goidanich leads to considerable damage in hot, dry seasons in many parts of the world, including Hungary. The present study investigated the mycelial compatibility of 53 Macrophomina phaseolina isolates, collected from sunflower, maize and soybean in different regions of Hungary, in order to characterize the diversity of the pathogen. Compatible isolates were identified by growing the isolates in direct contact with each other on potato-dextrose agar medium under laboratory conditions. Most isolates were compatible. Only 24 pairs of all the possible paired combinations showed incompatible relationships. Even geographically distant isolates were found to be compatible. Some Serbian isolates were compatible with all the Hungarian isolates and one Spanish isolate tested in this work. The latter exhibited incompatibility only with a single Hungarian isolate. These results suggest that the same or very similar genotypes may spread over long distances, probably through the transportation of seeds or crops contaminated with microsclerotia. This is the first report on the compatibility of Macrophomina phaseolina isolates in Hungary.
