† If a trait appears inside parentheses i.e. (RR), then it is not part of the variety name.

‡ All yields are adjusted to 13% moisture.

  • Average moisture at harvest.

Lodging = 1 to 5 scale; where 1 = 95% of plants erect; 2.5 = ~50% of plants leaning at angle ≥ 45°; 5 = 95+% of plants leaning at an angle ≥ 45°.

Maturity = days after planting (DAP).

Leaf Holding = 1 to 5 scale; where 1 = no leaves remaining on stems at maturity; 5 = 90+% of leaves remaining on stems at maturity.

Seed Quality = 1 to 5 scale; where 1 = < 5% of seeds showing disease or split seed coats; 5=95+% of seed are diseased or have split seed coats.

Protein & Oil on dry weight basis.

SDS disease ratings were taken at the Highland Rim Experiment Station on 9/3/2015

DI = disease incidence = percentage of plants with symptoms

DS = disease severity = score of leaf chlorosis and necrosis; 0 = no symptoms; 9 = plant death before normal defoliation due to senescence.

DX = disease index = (DI x DS / 9)

Disease ratings for Frogeye Leaf Spot are from 1-9, where 0=no disease & 10=maximum amount of plant disease or plant death. Ratings taken 8/28/14 in Knoxville, TN
