  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: Dyer, Gibson, Hamblen, Haywood, Madison *Treated plots sprayed with Quadris TOP @ 8 oz./Acre + 1% Induce @ R3 growth stage. RECM varieties planted June 1 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 – 17% with an average of 4% and Target spot ranged from 0 – 30% with an average of 4%. Disease ratings at JAX: Frogeye leaf spot ranged from 0 – 54% with an average of 11% and Target spot ranged from 0 – 24 with an average of 3%. 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.
