The materials in this subset were identified by Barker and McKenzie, 1996 for tolerance to the Orange Wheat Blossom Midge.

Global warming may increase insect distribution and activity, and imperil crops. The Orange wheat blossom midge (OWBM) is a devastating insect pest affecting wheat production, affecting the crop during the narrow window between heading and anthesis. OWBM larvae cause most damage by feeding on developing grain and economic risk is highest in crops intended for seed or milling.
