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.   *Treated plots sprayed with Quadris TOP SBX @ 7 oz./Acre + 0.25% Induce @ R3 growth stage. RECM varieties planted June 3, sprayed Aug 12, and harvested Nov 3. JAX1 varieties planted June 2, sprayed Aug 10, and harvested Oct 22. JAX2 varieties planted after wheat June 26, sprayed aug 25, and harvested Nov 6.   LOW, MOD, and HIGH is a relative ranking of disease severity at each location. Other diseases noted: CLB=Cercospora leaf blight;  ‘ – ‘ indicate variety was not tested at that location or data was not collected Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 5% with an average of 2%; Target spot ranged from 0 – 0.8% with an average of 0.1%. Disease ratings at JAX1: Frogeye leaf spot ranged from 0 – 4% with an average of 0.6%; Target spot ranged from 0 – 6% with an average of 2.7%; Sudden Death Syndrome (SDS) index ranged from 1 – 23 with an average of 10 disease index. Disease ratings at JAX2 (after wheat): Frogeye leaf spot ranged from 0 – 5% with an average of 2%; Target spot was not observed; there was soybean rust present but it was not rated.   Disease ratings & yield data compiled by Dr. Heather Kelly & Alyson Horner from replicated plots at the Research and Education Center at Milan, the West Tennessee Research and Education Center, and on-farm location in Jackson.
