BOZEMAN - Scientists at Montana State University's College of Agriculture have developed two new lines of Clearfield herbicide-tolerant winter wheat, which are available for licensing.

The lines, known as MTCL1067 and MTCL1077, were derived from the Yellowstone variety and retain the Clearfield two-gene resistance to the imidazolinone family of herbicides.

Tested at locations across Montana, both of the new lines are similar to Yellowstone and to each other in performance, end-use quality, and disease reaction. The first of the new varieties, MTCL1076, grows to maturity earlier and is taller than the Yellowstone variety.

Both lines appear to have improved stem rust resistance compared with their backcross parent and are superior in yield performance compared with the two-gene Clearfield winter wheat cultivar predominantly used in Montana, AP503 CL2.

To be eligible for licensing, prospective licensees must have a current Clearfield commercialization agreement with BASF. Companies may only license one of the two varieties. The licensing is contingent on BASF's approval of the new varieties following its review of MSU's data on the new lines' herbicide tolerance.

Companies with a current BASF Clearfield agreement interested in licensing the MTCL1067 or MTCL1077 wheat lines must submit a license proposal by June 15, 2012.

The new varieties of winter wheat are the latest technologies available for licensing at MSU. For more details and to inquire about licensing, interested companies should contact Nick Zelver with the MSU Technology Transfer Office at (406) 994-7868, or by e-mail at

Currently, MSU has 214 licenses from technologies developed by faculty and researchers. Of those, 95 licenses are with Montana companies.
