Seventy-nine isolates of Cylindrocladium crotalariae originally obtained differences were noted among isolates from the resistant host. As isolates from plants of the resistant peanut cultivar NC 3033 and 1 1 isolates became adapted to NC 3033, they tended to become less adapted to obtained from susceptible plant species including peanut were tested by Florigiant. Following only one cropping cycle of the resistant host, inoculating replicates of the susceptible cultivar Florigiant and resistant virulence specific for NC 3033 increased in a previously nonselected cultivar NC 3033. The mean virulences of isolates from the susceptible hosts pathogen population. The results indicate that a potential exists for race did not differ significantly from those of isolates from the resistant host. development in C. crotalariae even though corresponding resistance in the When disease data were fitted to a pathogen virulence model, however, host appeared to be quantitatively inherited
