The principal objectives of this project were to identity and develop disease resistant and drought resistant sorghum germplasm in diverse backgrounds for use by collaborating LDC and US scientists, and to collaborate with host country scientists in all aspects of their crop improvement programs.


1. Develop and distribute early generation breeding materials involving disesase and drought resisantce specfically for selection and use in host countries with emphasis on Hondruas, Sudan, Mali, and Niger 2. Screen and evaluate in the U.S. and host countries, sorghum germplasm sources for drought tolderance and for resistance to diseases of importance in the U.S. and LDCs. 3. Develope high yielding cultivars with resistance to internationally important disesase wtih emphasis on downy mildew, charcoal rot, grain mold, weathering anthracnose, head smut, head blight, viruses and acremonium wilt. 4. Develope through breeding and selection, agronomically desirable types with superior combinations of pre-and post-flowering drought dolerance and lodging resistance for use in the U.S. and host countries. 5. Develop cooperative disease and drought trials and distribute, evaluate, and utilize improved disease and drought resistant breeding materials, and new germplasm sources in host countries. 6. Collect new sorghum germpalsm, including wild types, evaluate for traits needed in the U.S. and developing countries, and introgress these traits into improved lines.


The disease resistance and drought resistance breeding programs and the germplasm program continued to progress with several breeding lines ready for release, as well as some new converted lines. New cultivars were introduced into the US, evaluated , and used in crosses. A large amount of new germplasm containing a large number of desirable traits was generated by the new crosses. Large numbers of germplasm lines of all categories were distributed to LDC, other international, and domestic collaborators.
