摘要：

The necrotic symptoms (spraing) in tubers caused by Potato mop-top pomovirus (PMTV) have become a severe problem for potato production in Scandinavia. PMTV is transmitted by the powdery scab pathogen (Spongospora subterranea) and no methods for control are currently available. Two breeding lines (NY99 and NY103) from the Cornell University potato breeding program, two tuberosum x acaule lines (TA3.8.3.3 and TA3.5.3.7) from the International Potato Center (CIP), and one line (IvP35) of Solanum phureja were tested for resistance to PMTV in field trials in Sweden in 1998 and 1999. In both years, NY99 had a low incidence of PMTV infection in tubers, and the infected tubers showed a low accumulation of PMTV, indicating that NY99 is a promising new source of resistance to PMTV for breeding programs. Furthermore, it may be suitable for cultivation in Scandinavia, which, however, needs to be evaluated in more extensive field trials.
