Table 46. Mean yields and agronomic characteristics of three Maturity Group IV Liberty Link soybean varieties evaluated in four REC tests in Tennessee for three years, 2014 – 2016 (n=12).

† 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 Milan Experiment Station, in both irrigated and non-irrigated tests, on 9/13/2016

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)
