The principal objectives of TAM-122 were to identify and develop disease resistant and drought resistant sorghum germplasm in genetically diverse backgrounds for use by host country and U.S. scientists, and to collaborate with host country scientists, especially those in Mali, Honduras, and Sudan, in all aspects of their crop improvement programs.


1. Enhance the germplasm of LDC's by developing and distributing early generation breeding germplasm involving genetically improved disease and drought resistance andother desirable traits for use and selection in host countries with emphasis on Honduras, Sudan, Mali, and Niger. 2. Develop high yielding cultivars for LDC's and the U.S. with genetically enhanced resistance to internationally im-portant diseases with emphasis on downy mildew, charcoal rot, grain mold/weathering, anthracnose, head smut, head blight, viruses, and acremonium wilt. 3. Develop through breeding and selection, high yielding,agronomically desirable types with superior combination of pre-and post-flowering drought tolerance for use in the U.S. and host countries, 4. Identify, in basic sorghum germplasm lines, new sources of drought tolerance and resistance to diseases of impor-tance in the U.S. and LDC's. 5. Collect new sorghum germplasm and evaluate for traits needed in the U.S. and developing countries, and introgressthese traits into improved lines.
