Successful Field Trials Boost Advancement of Asian Soybean Rust Resistance

Endemic to most soybean growing regions of the globe, RAS can cause yield loss ranging from 10 to 80% in the countries where it is established, posing a significant risk to farmers and agricultural systems. soy in Latin America are particularly vulnerable to this fungal disease due to mild winter conditions, which allow the fungus to survive year-round. The transgenic trait being developed by 2Blades and Corteva will provide an additional disease management tool to farmers in the region, increasing disease resistance durability and options for integrated disease management strategies.

“The results of the trial showed strong disease resistance in the transgenic soybean varieties tested,” said Dr. Tom Green, Head of Biotechnology at Corteva Agriscience. “Our partnership with 2Blades combines the strengths of our organizations in pursuit of our common goal of improving soybean productivity for farmers through Latin America via stronger plant genetics.”

2Blades’ knowledge of disease resistance, combined with Corteva’s skills in laboratory and field testing, as well as product development expertise, prompted the initial decision to collaborate in 2013. From 2013 to 2018, 2blades and Corteva undertook joint research to identify new gene resistance genes at the Federal Universidade de Viçosa in the Minas Gerais, Braziland the 2Blades group located within the Sainsbury laboratory in Norwich, United Kingdom. Additional testing was conducted across Corteva’s global research footprint.

“Lead genes from our collaboration continue to progress through our pipeline, allowing us to better understand their performance against key ASR pathogens impacting our growers in Latin America“, said Dr. Jeff Habben, who leads the Disease Resistance Discovery Group at Corteva Agriscience. “Reaching this collaborative milestone strengthens our trajectory and builds confidence in our approach.”

Although scientific advances have led to some improvements in soybean rust control in countries such as BrazilEnduring genetic resistance is an important tool for farmers to mitigate disease risk.

“Soybean rust is a major challenge for growers and must be tackled with an integrated strategy,” said Dr. Peter van Esse, vice president and group leader at 2Blades. “The genetic resistance against this disease will help give growers a powerful tool to manage the disease more effectively and sustainably.”
