This project sought to develop and deploy of standard and disease specific germplasm nurseries throughout the SADCC region to monitor variability and impact of major sorghum pathogens and to identify the best adapted sources of disease resistance.
1. Characterization of Macrophomina phaseolina from diverse hosts in Southern Africa 2. Disease development, economic impact, and host pathogen interaction of Exserohilumturcicum on sorghum cultivars with specific and general leaf disease resistance 3. Evaluate biological control techniques for sorghum down mildew of sorghum 4. Identify and characterize the Fusarium species occurring on pearl millet and sorghum in the SADCC region and assess their role in diseases of each host and their potential for mycotoxin rc.-contamination of seed used for human consumption. 5.Development of a race (pathotype) typing system for isolates ofColletotrichum graminicoia from sorghum usingRAPD biotechnology. 6. Determine stability and sources of resistance to majorfoliar pathogens through field screening nurseries at strate-gic locations, .
