1 Wheat Variety Performance Test Results General Information: The soft red winter wheat variety performance tests were conducted at three different sites: Adairville, Kentucky; Tenton, Tennessee; and Bertrand, Missouri. The KY location contained 73, the TN location contained 63, and the MO location contained 64 different varieties. Varieties were tested in no-till (MO and KY) and minimum till (TN) practices, however; the residue was burned off before planting in MO. The preceding crop for all locations was corn. Seeding rates used were as follows: MO and TN were 325 s/yd 2, while KY was 375 s/yd 2. Trials were planted using a Hege Drill with a row spacing of 7.5 inches, and were harvested with a Kincaid 8-XP research combine with a HarvestMaster Classic GrainGage. Plot dimensions used were 5 feet wide by 20 feet long. All sites contained four replications, and the experimental design used was randomized complete block. All locations were managed intensively with split applications of nitrogen, insecticides, herbicide sprays in the fall and spring, and a Feekes 5 and Feekes fungicide. Nitrogen applied to all locations was a January-February/March split application. The rate at KY was 55/65 pounds per acre, the rate at TN was 45/75 pounds per acre, and MO was 50/100 pounds per acre. At the Kentucky no-till site, there were four replications treated with a foliar fungicide at Feekes 5 and Feekes and four without. The objective for having four untreated replications is to see how each variety responds to the given level of head blight and foliar diseases, and then create a yield fungicide response column. At the Tennessee and Missouri sites all replications were sprayed with a fungicide at both timings. The MO site is irrigated, and our other locations are non-irrigated. Growing Season: Planting for the wheat growing season began on October 12 th in Missouri, then Tennessee on the 13 th, followed by Kentucky on the 18 th. Adequate moisture at time of planting made for excellent conditions. Emergence of wheat was delayed slightly at the Kentucky location due to colder than average temperatures beginning on October 23 rd and lasting through most of the month of November. Colder than average winter temperatures would continue to be the trend for all locations which slowed growth down, until February. February s warmer weather also brought extreme amounts of rainfall. According to the west TN site saw inches of accumulated precipitation for the month, which is far from the 5-year average of 3.93 inches. MO s total of 8.83 inches was considerably higher than its 5-year average of 3.12, with 6.82 inches of that total coming from the 19 th 26 th. Conditions were the same for KY. Varying weather would continue to create challenges for the wheat crop. High temperatures combined with areas of drought stress during grain fill periods would negatively affect grain quality and yield at harvest time. Test weights and yields at the MO and KY sites would be the greatest effected by these above average temperatures. Missouri s mean yield would be 23.5 bushels lower than the average of the previous two years, and the test weight would be approximately 2 pounds lower. While test weights in KY were not as affected as much, the mean yield would be 22 bushels lower than the 3-year average. Anthesis for the MO and KY locations took place from May 3 rd 8 th, during which high temperatures would not be problematic, however; from May 9 th 31 st (~75% of the grain fill period) there would be an increase in daytime high temperatures. According to in MO the 5-year average high temperature during this period is 80 F and the average high for this year was 88 F, while the KY 5-year average high is 79 F and the actual average high temperature was 86 F. The result of the heat stress during a very important time for the crop was reduced yield, test weight, and quality. That being said, some varieties handled the heat stress well, and still preformed positively. Disease pressure varied by location. Some varieties exhibited powdery mildew at the Kentucky site, and some moderate amounts of stripe rust were noted at the TN location. As a precaution, the TN location was sprayed with a fungicide across the entire plot at Feekes Septoria was present in moderate to high amounts at the KY and MO locations. Fusarium Head Blight was noted at the KY site in slight to moderate amounts. The combination of disease pressures contributed to the mean of 14.1 bushel fungicide response. Aphid presence was monitored closely this past growing season. The colder than typical winter could have played a big role in the low numbers reported all season.

2 Data Interpretation: Maturity groups are separated out into the following classifications: E = Early M = Medium L = Late ME = Medium/Early ML = Medium/Late The tables on the following pages have been prepared with the entries listed in order of performance, the highest-yielding entry being listed first. All yields presented have been adjusted to 13.5% moisture. At the bottom of the tables are there are three different values: LSD (Least Significant Difference), CV (Coefficient of Variation), and Grand Mean. The mean yields of any two varieties being compared must differ by at least the LSD amount shown to be considered different in yielding ability at the 5% level of probability of significance. CV is a measure of the error variability found within each experiment. It is the percentage that the square root of error mean square is of the overall test mean yield at that location. Grand Mean is the mean of all values in the group.
