† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability. * Asterisks after a hybrid name indicate the number of preceding consecutive years in the top-performing “A” group. ‡ For a full description of abbreviated biotech traits, see table 18. § 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.
