| Resumo: |
Late blight, caused by the oomycete Phytophthora infestans (Mont de Bary) poses one of the most important risks in production of organic potatoes. Favourable late blight conditions result in substantial losses in yield and quality in susceptible genotypes. In a series of field experiments between 2012 and 2015 at three organic sites in northern and southern Germany 148 cultivars assessed the outcome of decades of german late blight resistance breeding. The phenotyping of this diversity panel under natural conditions showed significant differences in the level of resistance within and across all maturity classes. These results were then used for a Single Nucleotide Polymorpism (SNP) assay on a 12k Infinion chip to locate QTLs for late blight resistance. Significant SNPs could be found for the traits late blight infection, maturity and maturity corrected late blight infection. These SNPs will be used for development of PCR markers for marker assisted selection in ongoing resistance breeding.
