Since host plant resistance to Asian soybean rust (ASR) has not yet been employed as a major control method, probably due to a lack of known source for stable and strong resistance. It is now possible to screen for soybean rust resistance in two newly established rust screening nurseries in China. Screening priorities will be for new PI's along with previously identified possible rust-resistant plant introductions. One identified line consistently showed partial resistance under ASR infection in a multiple Chinese test as well in University of Georgia field trials. This partial resistant line was used as the resistant source in crossing into elite Michigan germplasm. To date, a...
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
