A. Virus Epidemiology
1. Develop high throughput detection tests
2. Identify vector species and determine their major flying times
3. Identify alternative hosts and
4. Evaluate seed transmission and effect in seed vigor
B. Plant-Virus Interactions
1. Evaluate the role of SVNaV isolates and soybean germplasm in observed symptomology and
2. Evaluate cultivar reactions to mixed infections with major soybean viruses
C. Resistance to SVNaV
1. Screen soybean germplasm for resistance
2. Study inheritance of resistance
3. Develop molecular markers linked to resistance and
4. Breed for resistance
