Stem rust resistance testing
In the Central Plains, fungal diseases have been virtually non-existent during the last two growing seasons. So how do we make progress fighting disease when there is no selection pressure out in the field?
Take it to the lab.
First, we propagate our favorite race of stem rust by infecting a highly-susceptible variety planted in ‘spreader trays.’ Pictured below is a high-yielding line that also excels at making lots of spores!
This is an example of off-season activities at the Wichita Research Station.
