Variety Testing Data Is Posted

It was an extremely late harvest season, but 2009 data from the University of Illinois Variety Testing program are now posted online. This site is an extremely valuable resource for your soybean variety selections for 2010. You can compare your current varieties with varieties of interest for next year at the locations closest to you as well as over multiple locations in the appropriate region and maturity group (MG) categories. The state is broken into five testing regions, and multiple MGs were tested in each. Average yields at the testing locations in 2009 ranged from 49 to 67 bu/acre. Within region and MG, there was a 12% to 27% advantage for varieties that performed in the top 10% versus the bottom 10%. Additional variety information, including SCN resistance data and disease ratings, are provided by the Varietal Information Program, funded by the Illinois Soybean Association, and can be found at If you don't find data for the soybean varieties you use, nominate a variety to be tested in the future sponsored by the Illinois Soybean Association.--Vince M.
