† 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.
†† 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 Knoxville, Springfield irrigated, Milan irrigated, Milan non-irrigated, and Jackson 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 Springfield 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.
