† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability. * Hybrids marked with an asterisk were in the top performing “A” group across locations 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.

¶ Lodging values do not typically follow a normal distribution, therefore statistical tests to compute LSD were not performed and only mean values are reported. Values highlighted in light orange are above average for a given trait, MS letters highlighted in dark orange are in the “A group”, indicating no statistical difference from the top-performing variety, for a given trait.
