Table A-2. Mean yields and agronomic data from Knoxville, TN, MG-3

Table A-2. Mean† yield and agronomic traits of 7 Maturity Group III (3.0 – 3.9) soybean varieties evaluated in small plot replicated trials with irrigation at the East Tennessee AgResearch and Education Center in Knoxville, Tennessee during 2021. 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 were measured post-harvest using NIRS and are reported on a dry weight basis.

‡‡ Frogeye was evaluated using a 1 to 9 scale, with 1 indicating no disease. Evaluated in mid-September.

§§ Seed quality was evaluated visually post-harvest using a 1 to 5 scale, with 1 indicating no shriveled or damaged seed.

¶¶  Purple stain was evaluated visually post-harvest using a 1 to 5 scale, with 1 indicating no purple stain.
