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: Cannon, Crockett, Dyer, Franklin, Gibson, Giles, Hardeman, Henry, Obion, Perry, Trousdale (KY), Warren, Weakley, Ballard (KY), Calloway (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.
Disease ratings at RECM: Frogeye leaf spot ranged from 0 – 56% with an average of 12%; Brown spot ranged from 23 – 65% with an average of 39%; and Target spot ranged from 0 – 23% with an average of 5%.
Disease ratings at JAX: Frogeye leaf spot ranged from 1 – 63% with an average of 20%; Brown spot and Target spot were only rated as present or absent (noted in ‘Other Diseases’ column)
Disease ratings at WTREC: Frogeye leaf spot ranged from 0 – 21% with an average of 5%; Brown spot ranged from 15 – 35% with an average of 22%; and Target spot ranged from 0 – 13% with an average of 2%. Lodging was recorded for a plot if >50% of the plants were leaning at angle ≥ 45° and is reported on a 0 to 4 scale based on the 4 replicate plots for each variety (e.g. 4=4 of 4 plots, 3=3 of 4 plots, etc.)
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.
