title: Somatic fusion for combining virus resistances in Solanum tuberosum L.
abstract: Dihaploid genotypes of potato, containing the dominant allele for extreme resistance to PVX and/or PVY, were used in a fusion program in order to analyze the behaviour of the two monogenetic resistances after fusion. Eighteen different fusion combinations were performed and regenerated hybrids were tested by ELISA for their virus resistance. In most of the combinations an addition of the two qualities was found, but a few deviating clones were observed. The possible reasons for the phenotypic disappearance of resistant alleles are discussed.
