General Information Research and Education Center Tests: The 2011 variety performance tests were conducted on 71 soft red winter wheat varieties in each of the physiographic regions of the state. Tests were conducted at the East TN (Knoxville), Plateau (Crossville), Highland Rim (Springfield), Middle TN (Spring Hill), Milan (Milan) and West TN (Jackson) Research and Education Centers and at the Agricenter International Research Center in Memphis. All varieties were seeded at rates from 26-32 seed per square foot (Table 1). Plots were seeded with drills using 7–7.5 inch row spacings. The plot size was six, seven, eight or ten rows, 20 to 30 feet in length depending on location equipment. Plots were replicated three times at each location. Seed of all varieties were treated with a fungicide. County Standard Tests: The County Standard Wheat Test was conducted on 15 soft red winter wheat varieties across eight counties in Middle and West Tennessee (Dyer, Fayette, Franklin, Gibson, Henry, Lake, Moore and Weakley). Each variety was evaluated in a large strip-plot at each location; thus each county test was considered as one replication of the test in calculating the overall average yield and in conducting the statistical analysis to determine significant differences. At each location, plots were planted, sprayed, fertilized and harvested with the equipment used by the cooperating producers in their farming operation. The width and length of strip-plots were different in each county; however, within a location in a county, the strips were trimmed on the ends so that the lengths were the same for each variety, or if the lengths were different, then the harvested length was measured for each variety and appropriate harvested area adjustments were made to determine the yield per acre. Wheat and Oat Silage Tests: In order to evaluate the 2011 wheat and oat varieties for silage yield, duplicate tests with differing randomizations were planted at the Middle Tennessee Research and Education Center. These data will be presented in the UT Extension Silage Tests publication SP618 later this year. Growing Season: Hot, dry conditions during the fall of 2010 promoted early harvesting of summer crops; however, planting of small grains was later than usual across much of the state. The winter temperatures were unusually cold with some freezing damage to plants at some locations. According to the Tennessee Agricultural Statistics Service (TASS), the crop tolerated the winter in good condition and spring conditions were very good for wheat growth, albeit some areas experienced heavy rains and flooding. The wheat crop experienced a low incidence of disease and the weather conditions at maturity were very favorable for harvest. The result was a record 70 bu/a state average wheat yield in 2011. This record yield surpasses the previous best of 64 bu/a set in 2006. Tennessee producers planted approximately 390,000 acres of wheat in the fall of 2010, up 50% from the previous year. Approximately 310,000 acres were harvested for grain, which was 130,000 acres more than in 2010. The remaining 80,000 acres were utilized for hay, silage, cover crop or were lost due to flooding. According to TASS, the total wheat production in Tennessee for 2011 is 21.7 million bushels, more than twice the production from 2010.

Interpretation of Data The tables on the following pages have been prepared with the entries listed in order of performance, with the highest-yielding entry being listed first. All yields presented have been adjusted to 13.5% moisture. At the bottom of the tables, LSD values stand for Least Significant Difference. 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. For example, given that the LSD for a test is 8.0 bu/a and the mean yield of Variety A was 50 bu/a and the mean yield of Variety B was 55 bu/a, then the two varieties are not statistically different in yield because the difference of 5 bu/a is less than the minimum of 8 bu/a required for them to be significant. Similarly, if the average yield of Variety C was 63 bu/a then it is significantly higher yielding than both Variety B (63 - 55 = 8 bu/a = LSD of 8) and Variety A (63 - 50 = 13 bu/a > LSD of 8). Also, the coefficient of variation (C.V.) values are shown at the bottom of each table. This value 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. For example, a C.V. of 10% indicates that the size of the error variation is about 10% of the size of the test mean. Similarly, a C.V. of 30% indicates that the size of the error variation is nearly one-third as large as the test mean. A goal in conducting each yield test is to keep the C.V. as low as possible, preferably below 20%.

Results

Yield and Agronomic Traits: During 2011, 71 wheat varieties were evaluated in seven research and education center (REC) tests, and 15 varieties were evaluated in eight county standard tests (CST). All 15 varieties in the CST were also present in the REC tests (Table 5). Eleven companies and five universities entered varieties into the tests this year. The average yield of the 71 varieties in the 2011 REC tests was 70 bu/a (range from 58 to 80 bu/a, Table 2). The varieties ranged in maturity from 218 to 226 days after planting (DAP) with most of the varieties clustering around 220. The test weight values ranged from 51.6 to 57.4 lbs/bu (Table 3). The average yield of the 20 varieties in the county tests was 89.4 bu/a, with individual varieties ranging from 84.9 to 92.2 bu/a. The test weight values ranged from 54.6 to 59.9 lbs/bu (Table 4).

-------------------------------------------- Oats ---------------------------------------------

Results

A fall-seeded oat test was conducted at the East TN (Knoxville) and Middle TN (Spring Hill) Research and Education Centers (REC) during 2010-2011 on 23 winter oat varieties / breeding lines. The Spring Hill location experienced storm damage, resulting in seed loss and lodging, which made harvest unfeasible and is therefore not included in these analyses. The average yield of the 23 oat entries was 69 bu/a, ranging from 36 to 91 bu/a. Test weights ranged from 30.3 to 43.3 lbs/bu. The official test weight for oats is 36 lbs/bu. A moderate amount of winter injury occurred on some of the breeding lines at Knoxville, reducing overall stands for those lines. Eight of the 23 varieties have been evaluated over the two-year period 2010 - 2011. Four of the 23 varieties have been evaluated over the three-year period 2009 – 2011.
