Summary
Each of the three soybean accessions P.I. 200492, P.I. 230970, and P.I. 462312 (Ankur) has a dominant gene governing specific resistance to Phakopsora pachyrhizi, the causal agent of soybean rust. These genes occur at a different locus in each accession and not in an allelomorphic series. Additional sources of specific resistance recently identified were accessions P.I. 459024 and P.I. 459025, both from southern China, and Glycine soja accession P.I. 339871 from Korea. The genetic basis for rust resistance in these accessions is being investigated. The resistance of P.I. 459025 and P.I. 339871 was of special interest because it was effective against P. pachyrhizi isolate Taiwan-80-2, which caused disease in P.I. 200492, P.I. 230970, and P.I. 462312.
