Breeding lines have been developed from crosses with resistant lines. Evaluation and selection among these lines in field experiments with natural rust pressure will continue toward the development of new, improved resistant germplasm releases. Potential new sources of resistance will be evaluated in field screenings and new populations developed as warranted. The efficacy of single-gene resistance will be evaluated using fungicide spray/no spray field experiments. Similar fungicide experiments will be used to identify and evaluate quantitative resistance in a recombinant inbred population. Where appropriate, molecular markers will be used to identify specific genes and qualitative trait loci.
