Table 5-a. Mean† yield and agronomic traits of 7 Maturity Group III (3.0 – 3.9) soybean varieties evaluated in small plot replicated trials at eight AgResearch and Education Center locations in Tennessee during 2021. Analysis included variety performance over 1 yr (2021) period. All MG-3 varieties evaluated this year were new; therefore, 2 yr and 3 yr analysis are not presented.

† Varieties that have any MS letter in common are not significantly different at the 5% level of probability. 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.
* Asterisks after a name indicate the number of preceding consecutive years in the top-performing “A” group.
‡ 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).
¶ Protein and oil on a dry weight basis and were evaluated at the Knoxville location

§ All yields are adjusted to 13% moisture.
†† SDS was evaluated as disease incidence (percentage), disease severity (1 to 9, with 1 indicating no disease), and disease index (DI x DS/9). All locations were evaluated,
but only Milan irrigated and Milan non-irrigated exhibited significant variation and are included in the analysis.
‡‡ Frogeye was evaluated using a 1 to 9 scale, with 1 indicating no disease. All locations were evaluated, but only Knoxville and Milan non-irrigated exhibited significant
variation and are included in the analysis.
§§ Seed quality was evaluated visually post-harvest using a 1 to 5 scale, with 1 indicating no shriveled or damaged seed. Trials were evaluated at the Knoxville location only.
¶¶ Purple stain was evaluated visually post-harvest using a 1 to 5 scale, with 1 indicating no purple stain. Trials were evaluated at the Knoxville location only
