Winter wheat cultivars susceptible or intermediate in reaction to stripe rust were crossed. Several generations of selection resulted in progeny with high levels of resistance. Additive genes for resistance were detected in cultivars, which normally appeared susceptible, by maintaining the inoculated plants at a high temperature regime and then comparing the reactions obtained with those of a very susceptible control cultivar. A number of wheat lines were developed that showed uniform resistance to several isolates of Puccinia striiformis.
