Exploring the natural biodiversity of potato for late blight resistance

This paper gives an overview of the activities in Sub-project 4 of the BIOEXPLOIT programme. The European genebank collections of potato need to be narrowed down into (customized) core collections by focusing on loci associated with disease resistance. Therefore, new and more efficient molecular methods are being developed to identify these loci, extensive genotyping of resistance to Phytophthora infestans and signalling loci is being performed, and genotyped selections of accessions are phenotypically analysed for their resistance specificities. The results of these activities are being assembled in an integrated database
