The management of potato cyst nematodes using resistant Solanaceae potato clones as trap crops

The concept of using a range of Solanaceae potato clones as trap crops for potato cyst nematode (PCN) management was investigated. A series of field trials were undertaken from 1999 to 2002 that evaluated 10 clones of either wild Solanum potato species, breeder’s hybrid lines or commercial cultivars. All had high resistance to all known PCN pathotypes (both Globodera rostochiensis and Globodera pallida) and the ability to stimulate high levels of PCN hatch. Investigations showed potential for the development of some clones as a means of reducing high PCN field population levels and for use by organic potato producers.
