Data Provided by Ryan Blair, Ext. Area Specialist, Grain and Cotton Variety Testing, and Extension agents in counties shown above. † Hybrids that have any MS letter in common are not significantly different in yield at the 5% level of probability. * Asterisks after a hybrid name indicate the number of preceding consecutive years in the top-performing “A” group. § All yields are adjusted to 15.5% moisture. Highlighted cells indicate hybrids that were above average and bold/underline values indicate the top yield, within a location. County locations include: Fayette, Gibson, Henry, Lake, Loudon, Madison, Monroe, Trousdale, Wayne, and Weakley.
