Identify new sources of resistance through extensive screening of adapted and exotic breeding lines and cultivars. Incorporate resistance through recurrent family and simple mass selection in populations, which are segregating for the Sumai 3 FHB resistance and other quantitative sources for resistance. Advance resistant plant and families into the variety development. Evaluate the effectiveness of the Sumai 3 molecular markers in heterogeneous populations. Screen diverse lines, cultivars, and populations for genetic variation in DON content.
