2022 Annual Report
Accomplishments
1. New sugar beet genome provides breeders with toolbox for pest resistance. Pests and pathogens are a major cause of losses in U.S. sugar beet production, with up to 80% loss reported for some outbreaks. ARS researchers in Fort Collins, Colorado, and collaborators used cutting-edge genome sequencing technologies to develop the most complete genomic maps for sugar beets and their wild relatives. The team identified a group of sugar beet lines and wild relatives that resist Rhizoctonia Crown and Root Rot and sugar beet cyst nematode. These plants can now serve as the basis for using genetic markers to breed this resistance into commercial sugar beet lines. In addition to these sugar beet-specific findings, the approach is transferable to breeding objectives in many important agricultural crops in the U.S. and worldwide.
