Abstract
Results are presented from a three gene population genetics and dynamics model of herbicide resistance in annual ryegrass. The models predictions are compared with those of other one and two gene resistance models to validate the modelling approach which will ultimately be used to develop a five-gene herbicide resistance model. The importance of initial gene frequencies for resistance in unselected ryegrass populations and of the selection pressure imposed by herbicides in determining rates and patterns of multiple and cross-resistance development is demonstrated.
