Technical Abstract: Significant strides were made this last year in the development of wheat breeding lines with resistance to greenbug, Russian wheat aphid, and bird cherry-oat aphid. Several highly productive wheat lines with resistance to Russian wheat aphid were advanced through various testing phases. Testing and selecting for greenbug resistance continues, with greenbug-resistant wheat lines now in various stages of development. One will appear in the 2000-01 edition of the Oklahoma Elite Trial, the final stage of statewide yield testing before testing in regional USDA uniform trials. As a result of large-scale testing efforts, we have identified 17 wheat strains with high levels of resistance to bird cherry-oat aphid feeding. One of these lines happens to be an Oklahoma selection that was obtained from the USDA National Small Grains Collection in Aberdeen, Idaho. Tests are ongoing to verify the high levels of bird cherry-oat aphid resistance and begin the process of moving this resistance into elite Oklahoma breeding lines.
