| Abstract: | A high level of PLRV resistance has been found in four diploid genotypes originating from resistant ancestors widely utilized in European potato breeding. Plants of these genotypes were difficult to infect not only with aphids, but also with graft inoculation. Their resistance is associated with limited virus spread, but not with intolerance. The level of PLRV resistance in these genotypes appears to be comparable to a high level of resistance detected recently in some wild potato species. Evaluation of virus concentration after graft inoculation with PLRV was found useful in the selection of potato genotypes highly resistant to PLRV. |
