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, Franklin, Gibson, Henry, Hickman, Lake, Obion, Weakley

 

*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 – 6% with an average of 3%; Brown spot ranged from 9 – 14% with an average of 11%; and Target spot ranged from 0 – 15% with an average of 2%.

Disease ratings at JAX: Frogeye leaf spot ranged from 1 – 14% with an average of 8%; other diseases were not rated or noted at this location for this maturity group

 

Disease ratings & yield data compiled by Dr. Heather Kelly from replicated plots at the Research and Education Center at Milan (RECM, which is irrigated and had moderate disease pressure), and on-farm location in Jackson (JAX, which is dry land and had severe disease pressure). County data provided by Ryan Blair, Ext. Area Specialist, and the extension agents.
