Inheritance of resistance to rust (Phakopsora pachyrhizi) in soybeans

Abstract

A study was conducted to determine the inheritance of resistance to soybean rust in three soybean accessions-PI200492, Tainung 3 and Tainung 4. The results suggest that PI200492 and Tainung 3 contain the same single dominant gene for resistance, and that Tainung 4 contains two dominant genes for resistance, one of which is identical with that in PI200492 and Tainung 3.
