Table 7-a. Mean yield and agronomic traits of 39 medium-season (114-116 DAP) corn hybrids evaluated in small plot replicated trials at eight 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.
¶ 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.
