 ‡ Data Provided by Ryan Blair, Ext. Area Specialist, Grain and Cotton Variety Testing, and Extension agents in counties shown above.† Varieties that have any MS letter in common are not significantly different in yield at the 5% level of probability.* Varieties marked with an asterisk were in the top performing “A” group for two (**) or three (***) consecutive years within the previous three year evaluation period.

• All yields are adjusted to 13% moisture.
