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: Benton, Crockett, Decatur, Dyer, Fayette, Franklin, Gibson, Giles, Haywood, Henry, Loudon, Madison, Marion, Montgomery, Obion, Tipton, Weakley, McCracken (KY)

 

*Treated plots sprayed with Quadris TOP @ 8 oz./Acre + 1% Induce @ R3-R4 growth stage. RECM varieties planted June 1, JAX planted May 23, and WTREC planted June 13 after wheat.

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 † indicates ratings not able to be taken

Disease ratings at RECM: Frogeye leaf spot ranged from 38 – 53% with an average of 45%; Brown spot ranged from 20 – 40% with an average of 26%; and Target spot ranged from 0 – 14% with an average of 4%.

Disease ratings at JAX: Frogeye leaf spot ranged from 0 – 59% with an average of 14%; Brown spot ranged from 20 – 63% with an average of 49%; and Target spot ranged from 0 – 15% with an average of 3%.

Disease ratings at WTREC: Frogeye leaf spot ranged from 0 – 15% with an average of 3%; Brown spot ranged from 14 – 31% with an average of 23%; and Target spot ranged from 0 – 18% 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 (RECM, which is irrigated and had moderate disease pressure), on-farm location in Jackson (JAX, which is dry land and had severe disease pressure), and the West Tennessee Research and Education Center (WTREC, which was planted after wheat, is dry land and had low to moderated disease pressure due to regular crop rotation). County data provided by Ryan Blair, Ext. Area Specialist, and the extension agents.
