Abstract
A genetic analysis of resistance to crown rust in a series of natural populations of Lolium perenne by means of the diallel cross has revealed that heritability is high (58%) and that the genes concerned show complete but ambi-directional dominance for resistance. An environmental correlation was established between the degree of infection and productivity but no genetic correlation was present. The implications of this mode of control for resistance breeding procedures are briefly considered.Keywords
