MODELING THE CULTIVAR RACE INTERACTIONS IN INTERREGIONAL DISEASE SPREAD

Quantitative analysis of cultivar-race interaction at population level is important to deploy host plant resistance and stabilize pathogen p opulations or minimize their damage. This interaction is far more comp lex when inter-regional disease spread occurs. In this paper, a modell ing approach to the cultivar-race interaction is developed, which allo ws to simulate the cullivar-race interaction in inter-regional disease spread. Simulating example is presented to illustrate the application of our model.
