NDSU Winter Wheat Variety Trial Results for 2007 Available

Winter wheat variety trial results are available from the NDSU Extension Service.

The first winter wheat variety trial results are available from the North Dakota State University Extension Service at http://www.ag.ndsu.nodak.edu/aginfo/smgrains/ (or Google North Dakota small-grains page).

Available are data from trials conducted at Lisbon, Hettinger, Berthold and Roseglen.

Additional sites are being added as the data become available, says Joel Ransom, NDSU Extension Service agronomist for cereal crops and winter wheat testing coordinator.

""Winter wheat yields are somewhat lower than observed in last year’s trials in some locations because of heavy disease pressure and high temperatures during grain fill,"" Ransom says. ""For example, at the Lisbon site there was a 20-bushel yield increase when fungicides were applied.""

Across locations, Jerry, a NDSU release, CDC Falcon and CDC Buteo from Canada and Expedition from South Dakota were among the highest yielding. NDSU no longer has a winter wheat breeding program, so the winter wheat testing program includes new releases from Canada, Montana, South Dakota and Nebraska, as well as private companies.

""Darrell, a new joint release from South Dakota and Nebraska that was included in trials for the first time this year, looks like a promising variety for use in North Dakota,"" Ransom says. ""However, this observation is based on limited data. To select a variety that will consistently yield well, you need to use data from multiple locations and years, if they are available.""
