Characteristics of superior soybean breeding lines tolerance to rust (Phakopsora pachyrhizi Syd.)
<p>Soybean rust caused by Phakopsora pachyrhizi is one of the most important diseases which limits soybean production. The aim of this study was to evaluate the resistance of 28 superior soybean lines and their tolerance to rust. The study was conducted at a screen house and arranged in a comp...
