Abstract
F 2 progenies of six crosses of oats involving three sources of resistance to crown rust (Landhafer, Santa Fe, and Trispernia) were studied. Data from four crosses indicated the resistance of Landhafer to race 101 was conditioned by a single partly dominant gene. Data from two crosses indicated the resistance of Santa Fe to races 45 and 101 could be satisfactorily explained by assuming Santa Fe carried two genes for resistance, which were linked with a recombination value of about 23 percent. In one cross, the resistance of Trispernia to race 101 was attributed to the action of a single gene. In crosses involving Landhafer and Santa Fe, and Landhafer and Trispernia, certain segregates appeared that were more highly resistant than the parental types. The proportions of these segregates in the F 2 populations indicated the effects of the different genes in conferring resistance were cumulative.
