Evaluation of Selected Genotypes of Soybean for Resistance to Phakopsora pachyrhizi

S. Li and L. D. Young

June 2009


Soybean rust, caused by Phakopsora pachyrhizi Syd. & P. Syd., is one of the most destructive diseases of soybean worldwide. To identify sources of resistance to domestic soybean rust fungus populations for plant breeding, our strategy has been to evaluate soybean lines that were previously identified as resistant to foreign isolates. The objective of this study was to evaluate selected soybean lines with resistance to a Mississippi bulk isolate. The overall goal was to identify soybean lines that are resistant to both foreign and domestic P. pachyrhizi populations for plant breeding purposes.
