Breeding for potato cyst nematode resistance in <i>Solanum tuberosum</i>
Pia M Spychalla, Walter S. De Jong
Abstract
Abstract Two species of potato cyst nematodes (PCNs), Globodera rostochiensis (Woll.) and Globodera pallida (Stone), threaten potato ( Solanum tuberosum L.) production worldwide. PCNs are remarkably persistent in soil and can reduce potato yield significantly. The most sustainable approach to PCN control is deploying resistant cultivars. This review focuses on the knowledge needed to conduct a successful PCN resistance breeding program, including identifying resistance sources in wild species, introgressing them into cultivated potato, and sifting through clones to identify a marketable potato.
