  YLD= Avg. Yield @ 13% moisture MS= 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:Carroll, Coffee, Dyer, Fulton KY, Gibson, Giles, Haywood,Henry, Lauderdale, Madison, McCracken, Perry, Smith ,Weakley. *Treated plots sprayed with Quadris TOP @ 8 oz./Acre + 1% Induce @ R3 growth stage. RECM varieties planted May 31 and JAX planted May 23 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 location Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 24% with an average of 4%; Target spot ranged from 0 – 11% with an average of 2%; and Stem Canker ranged from 0 – 100% with an average of 28% Disease ratings at JAX: Frogeye leaf spot ranged from 1 – 40% with an average of 12%; and Target spot ranged from 0 – 23% with an average of 6%. Disease ratings & yield data compiled by Dr. Heather Kelly from replicated plots at the Research and Education Center at Milan and on-farm location in Jackson.
