Abstract

In several of the main potato production area’s in China the climate is favorable for P. infestans and consequently, potato late blight is one of the most serious threats to potato production in China. As part of a comprehensive monitoring program that we could establish for China we started genotypic studies on the current P.infestans population in China. We found much more genetic variation than previously reported. Nevertheless, the three mitochondrial haplotypes (Ia, IIa, IIb) and the SSR genotypes found in Chinese isolates were all strongly related to the region of origin. Many genotypes, as determined by multilocus SSR markers, are unique to specific regions and only two genotypes were found in multiple provinces located in the North of China. The genotyping analysis shows strong restriction of the spread of P. infestans but this could change radically if infected seed potatoes are transported between the different regions in China. Therefore we are currently intensifying our sampling and aim to set up a monitoring program similar to Euroblight
