 YLD= Avg. Yield @ 13% moistureMS= Varieties that have any MS letter in common are not statistically different in yield at the 5% level of probability.Varieties denoted with an asterisks (*) or (**) etc. were in the top performing group for consecutive years.County Locations include:Coffee, Decatur, Dyer, Gibson,Giles, Haywood, Henry, Madison, Marion, McCracken KY.*Treated plots sprayed with Quadris TOP @ 8 oz./Acre + 1% Induce @ R3 growth stage. RECM varieties planted May 31, JAX planted May 23 , and WTREC planted after wheat June 14.LOW, MOD, and HIGH is a relative ranking of disease severity at each location. Other diseases noted: SC=Stem Canker, CLB=Cercospora Leaf Blight, SDS=Sudden Death Syndrome;  ‘ – ‘ indicate variety was not tested at that locationDisease ratings at RECM: Frogeye leaf spot ranged from 0 – 20% with an average of 2%; Target spot ranged from 0 – 18% with an average of 3%; and Stem Canker ranged from 0 – 33% with an average of 4%.Disease ratings at JAX: Frogeye leaf spot ranged from 0 – 43% with an average of 8%; Target spot ranged from 0 – 21% with an average of 4%; and Stem Canker ranged from 0 – 36% with an average of 12%.Disease ratings at WTREC: Frogeye leaf spot was <1%; Target spot was <4%; the majority of the varieties has soybean rust but at levels too low to rate.Disease ratings & yield data compiled by Dr. Heather Kelly from replicated plots at the Research and Education Center at Milan, the West Tennessee Research and Education Center, and on-farm location in Jackson.County data provided by Ryan Blair, Ext. Area Specialist, and the extension agents.
