Andean cultivated potatoes in Peru, 1955
Collectors: H.J. Toxopeus and C.M. Ochoa
This mission was sponsored by the Dutch government and yielded 560 clones of Group Andigena, 113 of Group Stenotomum, 21 of Solanum juzepczukii and 17 of S. curtilobum. The aim of this collecting expedition was to collect cultivated South American potato clones with resistance to Heterodera rostochiensis (golden nematode). A part was lost because tubers were accidently removed from the cold storage room (see letter below). Another part could not be transformed into true seed and was lost due to virus infections.
