Potato blight tracking in Europe

28. april 2017

A team of researchers examining the ongoing evolution of the European population of the potato late blight pathogen now report on the 2016 data. Over 1600 samples were genotyped from 26 countries and entered into the EuroBlight database. More than 70% of the samples were of defined clonal lineages that have been observed in previous seasons. Some clones are widespread and have been present in Europe for more than a decade but two recently emerged clones showed marked local expansion in the 2016 season. The other 30% of the population comprised ephemeral genetically diverse isolates consistent with a source of oospore-borne inoculum. A clear regional pattern in the dominance of clones versus sexual recombinants was observed across Europe.
