Varieties of Solanum tuberosum, subsp. andigena, as a source of resistance to common scab

Abstract

High resistance to potato scab of two varieties of the tetraploid Solanum tuberosum subspecies andigena has been demonstrated in a replicated trial at Spring Hill in the central tablelands of New South Wales. The use of scab resistant varieties of this subspecies in a breeding programme would present less difficulty than the use of diploid or triploid species.
