Technology Description
ORCF-103 is best adapted to dryland wheat-growing regions in north-central Washington (blue shaded areas). Secondary areas of adaption (red regions) are the larger dryland wheat-growing regions in northeast Oregon and southwest Washington.
ORCF-103 is a cross between Eltan, FS-4, Stephens, and Madsen. It is an awned, intermediate stature, medium-late maturity variety with moderate straw strength. Not only is this variety high yielding, but what really sets ORCF-103 apart from OSU’s other CLEARFIELD varieties is its exceptional winter hardiness with good emergence and vigor from deep seeding. ORCF-103 is tolerant to snow mold, Fusarium crown rot, and cephalosporium.
Features & Benefits
Applications
Background of Invention
ORCF-103 incorporates an herbicide resistance trait and was developed in cooperation with BASF Corporation and USDA-ARS. When ORCF-103 is used in combination with Beyond® or Clearmax® at labeled rates, this CLEARFIELD® technology provides growers with an effective tool for control of several grassy weeds. ORCF-103 is a traditionally bred (not genetically modified) wheat variety that carries an altered form of the acetolactate synthase enzyme. The altered enzyme is not affected by imazamox, the active ingredient in Beyond® herbicide and one of the active ingredients in Clearmax® herbicide. ORCF-103 is resistant to the herbicide and many weeds are susceptible to damage when sprayed.
