An RFLP linkage map has been constructed based on an
intraspecific cross between two partially heterozygous, diploid
potato lines. The map consists of more than 400 RFLP loci and
covers ca. 90% of the potato genome. The genomic positions of a
series of functional genes of the potato have also been included
in the map. The RFLP linkage map was used to locate in the
potato genome monogenic resistance traits to the root cyst
nematode Globodera rostochiensis, potato virus X and the fungus
Phytophthora infestans. Quantitative trait loci (QTL) for
resistance to P. infestans have also been mapped. RFLP markers
closely linked to nematode resistance loci were converted into
allele specific PCR primers to be used in marker based selection
schemes.
