Technical Abstract: Soybean rust occurs in all major soybean-growing regions of the world except the North American mainland. Four single genes for rust resistance were previously identified in soybean. Race-specific resistance has also been found among non-cultivated Glycine species. Evaluation of plant introduction accessions in the USDA soybean germplasm collection for rust resistance was initiated in 2002 at the Fort Detrick BL-3 containment facility and at six international locations. Partial resistance, expressed as reduced pustule number and increased latent period, has also been reported, but has not been widely used in breeding programs. Tolerance, defined as yield stability under high disease pressure, has also been used in the past. Tolerance, along with race-specific and partial resistance, could offer a broad array of genetics to help minimize the impact of rust on soybean production.
