text: Through pioneering genetic studies (Fig. 16) of the pathogenicity of different physiological races of the pathogen and the resistance and susceptibility to rust in flax, H.H. Flor observed that there was a specific relationship between each gene determining pathogenicity in rust [avirulence (Avr ) genes] and corresponding genes [resistance (R ) genes] in the host determining resistance (Flor, 1956; Lawrence, 1988; Lawrence et al ., 2007).
