ABSTRACT:
The present invention relates to a plant of theCapsicumgenus, which plant exhibits resistance to Pepper mild mottle virus (PMMoV) pathotype 1.2.3 due to the presence of the L4 resistance allele in the genome of said plant, wherein the genetic information responsible for the SNFD phenotype is absent from or is repressed in the genome of said plant at least to such an extent that the SNFD phenotype is not expressed. The present invention further relates to a method of producing a plant of theCapsicumgenus that exhibits resistance to PMMoV pathotype 1.2.3, comprising the steps of a) providing a recipient plant of theCapsicumgenus that is susceptible to PMMoV pathotype 1.2.3 or a part thereof, and b) introducing into the genome of said recipient plant or a part thereof or a progeny plant thereof a genomic region comprising a truncated L4 resistance allele, wherein said allele comprises genetic information capable of being expressed in said plant or plant part or progeny plant thereby conferring resistance to PMMoV pathotype 1.2.3 to said plant or plant part or progeny plant, and wherein genetic information that confers the SNFD phenotype is absent from said allele at least to such an extent that the SNFD phenotype is not expressed.
