Transfer of resistance to potato leaf roll virus from Solanum brevidens into Solanum tuberosum by somatic fusion. Many wild Solanum species are regarded as important prptoplastos for disease resistance and tolerance to many abiotic stresses Hawkes, but their use in potato breeding is limited due to poor crossability and sterility protoplwstos interspecific hybrids.
