Reaction of wild solanum species to different viruses
Abstract
In the course of studying the host-virus relations of thirteen wild Solanum species and twelve viruses we established 69 new relations. According to the examinations immune host-virus relation existed between Solanum femandezianum and 5 viruses/belladonna mottle virus, cucumber mosaic virus, potato virus Y, tobacco necrosis virus and tomato ringspot virus. Hypersensitive, local reactions were given by 9 wild Solanum species to 3 viruses. Systemic susceptibility was shown by Solanum femandezianum to alfalfa mosaic virus. The number of local and systemic host-virus relations was fifty-three.
Incompatibility and compatibility pointed out between wild Solanum species and viruses may be important in resistance breeding on the one hand, and in the ecology of viruses, on the other.
