The rate of selection to virulence of potato cyst nematodes is simulated. Effects of number of resistance genes, level of resistance and alternation of different potato cultivars on durability of resistance is simulated.

Purpose of the model:

Model parentage: Spitters, C.J.T. & S.A. Ward, 1988. Euphytica S: 87-98.
