Compared to the predicted average yield of 61 bushels per acre for Wisconsin's winter wheat crop this summer, the results at the four trial plots overseen by the University of Wisconsin-Madison department of agronomy and the Extension Service look quite favorable.
In the report published in mid-August, the average yields for a total of 85 varieties - five of which were public sector entries.
The 80 commercial varieties came from 17 cooperating seed companies yielded in tight range averages of 89 bushels per acre at Chilton (Kolbe Seed Farms), 87 bushels at Lancaster, and 85 bushels at Arlington.
The Janesville plot posted an average yield of 67 bushels per acre. The Chilton plot had the highest average despite what was described as "severe winterkill" of several varieties while the Arlington plot had moderate winterkill.
Seven varieties posted average yields of above 100 bushels in the four replicated plots at Kolbe Seed Farms.
They were 105 bushels for Pioneer's 25R34, 104 bushels each for the AgriMAXX 413 and Tracy's TW 73-12, 103 bushels for the public Sunburst, Tracy's TW 52-13, and Pioneer's 25R47, and 101 bushels for Diener's D492W.
The only other variety topping 100 bushels was Legacy's LXW 1375, which had a yield of 105 bushels at Lancaster.
For the four plots, PIP's 733 had the top average yield of 92 bushels per acre - 99 at Arlington, 98 at Chilton, 94 at Lancaster, and 79 at Janesville.
PIP's 734 posted an average yield of 89 bushels per acre across the four plots.
The second highest average yield of 91 bushels was shared by Diener's D492W and Legacy's LXW 1375. The ranges were from 72 bushels at Janesville to 101 at Chilton for the D492W and from 75 bushels at Janesville to 105 at Lancaster for the LXW 1375.
Most of the varieties had per acre bushel yields in the 60s and 70s at Janesville. Yields in the 80s were the most frequent at Arlington while the Chilton plot had a spread of about 30 bushels per acre between the top and lower yielding varieties.
A high percentage of the yields at Lancaster were between 80 and 95 bushels per acre.
Except for the 57.6 pound test weight at Arlington, test weights at the other sites were in a tight range average of 59.2 pounds at Lancaster, 59.6 at Chilton, and 59.9 at Janesville.
A number of the varieties had test weights above 60 pounds at one or more plots.
