Molecular technique advances soybean rust resistance research
Date:5/16/2011

plant breeders trying to breed soybeans for resistance to soybean rust.

"We believe Q-PCR will save time and be more precise," he said. "The precision part is very important. The more precise you can be, knowing exactly what the line is reacting to, will lead to more precise mapping of the quantitative resistance genes."

The mapping of this particular quantitative resistance is very important to breeders selecting for rust resistance, Hartman said.

"It's a numbers game," he said. "In developing soybean cultivars, a large number of lines need to be evaluated so many inferior lines have to be discarded. In terms of breeding for soybean rust resistance, this technique can help determine which lines are more resistant to rust when it comes to the gray areas or quantitative resistance."
