Successor barley is a novel variety that exhibits tolerance to
residual IMI herbicide in soil and crop residue. It is well suited to dryland
and conservation/no-tillage agricultural systems in Eastern Oregon and
Washington. In a multi-environment trial, Successor met or exceeded the yield
of Survivor in all years in all but one location year. Additionally, it had
similar protein levels and test weights as Survivor. An on-farm trial showed
its potential under standard management conditions in a rotation following
winter wheat and was perceived favorably by the grower. Successor provides a
new option for growers to add barley into a rotation with Clearfield crops,
being only the second released variety with known tolerance to IMI residues.
