carrying Rpp2, Rpp4, and Rpp5 was evaluated by backcrossing it with a susceptible variety.
It was also evaluated eight lines which carry these Rpp genes against five Asian soybean
rust (ASR) isolates, in order to determine the likely range of resistance against ASR isolates
differing in pathogenicity. The results indicated that a high level of resistance against various
ASR isolates could be retained in lines carrying the three Rpp genes in susceptible genetic …
