2009 Variety Trials - South Dakota

SDSU 2009 Small Grain Variety Performance Results

Robert G. Hall, Extension agronomist – crops; John Rickertsen, research associate; Kevin K. Kirby, agricultural research mgr.; Bruce Swan, senior agricultural research technician; and Jesse Hall, agricultural research mgr.

These trial results are from the South DakotaCrop Performance Testing (CPT) Program and include averages for 2009 and the last three years (2007-09). A detailed version of these results and the procedures used to obtain the results are available at: http://plantsci.sdstate.edu/varietytrials/ .

Test Performance Results Yields (Table 1) – The entries Traverse, Faller, Howard, and Steele-ND at 100%; Briggs at 83%, RB07 at 67%; and Brick at 50% were to top-yield frequency entries for the past 3-years (2007-09). These entries exhibited very good yield stability or the ability to adapt to a wide range of production environments by being in the top-performance group for yield at more than 50% of the test locations. The entries Faller at 89%, Traverse at 78%, and Albany at 67% were to top-yield frequency entries for 2009.

Grain protein content (Table 2) – The entries Vantage at 15.8%; Kelby, Alsen, and Glenn at 15.1%, and RB07 at 15.0% produced protein values of 15% or higher.Bushel weight (Table 2) - The top bushel weight entries include the varieties Brick (59.1), Glenn (59.0), Barlow (58.7), and Breaker (58.6).Lodging (Table 2) – The entries Kelby, Kuntz, Samson,Brogan, Reeder, Breaker, Vantage, and Mott with lodging scores of 1 were better in lodging resistance compared to the other varieties.

Height (Table 2) - Granger and Mott were the tallest at 35” while Kelby, Kuntz, and Samson were the shortest entries.

Hard Red Spring Wheat Variety Recommendations for 2010

Recommendations are based on information from the South Dakota Crop Performance Testing (CPT) Program and regional university trials. Variety performance depends on genetics and environmental factors like temperature, moisture, plant pests, soil fertility, soil type, and management practices. The performance of recommended varieties in response to environmental conditions is generally better than that of other varieties. The better performance of a recommended variety, however, cannot always be guaranteed due to its complex response to the environment. Variety recommendations, including crop adaptation area (CAA) where each is most suited, are listed on the previous page.
