Table 11-b. Mean yield and quality traits of 20 full-season (>116 DAP) corn hybrids evaluated in small plot replicated trials at seven AgResearch and Education Center locations in Tennessee during 2020. Analysis included hybrid performance over a 1 yr (2020), 2 yr (2019-2020), and 3 yr (2018-2020) period.
† 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.
‖ Protein, Oil, and Starch 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.
