✦ Synopsis

Globodera rostochiensis resistance, Globoderapallida resistance, tuberous Solarium wild and primitive potato species, potato germplasm. SUMMARY Numerous accessions maintained in the potato collection of the 'German-Netherlands Potato Department of the Gene Bank in the Federal Research Center for Agriculture Braunschweig-Volkenrode' have been evaluated for resistance to potato cyst-nematodes. The results of several years testing for resistance to both Globodera rostochiensis and G. pallida are presented in this paper. It is concluded that resistance is predominantly found in some 17 species belonging to the series Tuberosa which have their geographical distribution mainly in the Andes. The geographical distribution of species with G. pallida resistance is discussed and it is pointed out that this resistance is mainly concentrated on the eastern slopes of the Andes (Cordillera oriental).
