* 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 31. § All yields are adjusted to 13% moisture. ‖ Lodging was evaluated on a a scale of 1 (no lodging) to 5 (complete lodging). C.V. is not reported for lodging since it was not measured using a ratio scale. ¶ Protein and oil on a dry weight basis. 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.
