Abstract

Research Note

RAPD markers were used to analyze the genetic structure in an Eutypa lata population from a single vineyard located in Charente, France. The high level of genotypic diversity and the lack of genetic disequilibrium between RAPD loci strongly suggest that the population originated from random mating. Its genetic structure was similar to that previously observed within a population from a vineyard located in Herault, France. No genetic differentiation was found between the two populations separated by 390 km. Ascospore-mediated gene flow would unify E. lata populations into a panmictic population at least at the geographic scale studied.
