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.  


*Treated plots sprayed with Quadris TOP SBX @ 7 oz./Acre + 0.25% Induce @ R3 growth stage.

RECM varieties planted May 28, sprayed Aug 19, and harvested Oct 9.

JAX varieties planted May 21, sprayed July 31, and harvested Sept 24.


LOW, MOD, and HIGH is a relative ranking of disease severity at each location. Other diseases noted: SDS=Sudden Death Syndrome;  ‘ – ‘ indicate variety was not tested at that location  


Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 2% with an average of 0.6% and Target spot ranged from 0 – 0.5% with an average of 0.1%.  

Disease ratings at JAX: Frogeye leaf spot ranged from 0 – 16% with an average of 3% and Target spot ranged from 0 – 1% with an average of 0.1%. 


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.
