† Hybrids that have any MS letter in common are not significantly different in yield at the 5% level of probability.

* Hybrids marked with an asterisk were in the top performing “A” group for two (**) or three (***) years within the previous three year evaluation period.

‡  For a full description of abbreviated biotech traits, see table 17.

  • All yields are adjusted to 15.5% moisture.
