5 Introduction The Uniform Wheat Variety Trial (UWVT), presented in the following pages, is coordinated and implemented by numerous Texas AgriLife Extension and Research faculty and staff, and Syngenta researchers. We also appreciate the cooperation from numerous Texas AgriLife County Extension Agents, producers, and private industry groups that contribute time, property, and seed to conduct these field trials. Wheat types within these yield trials included Hard Red Winter Wheat (HRWW), Soft Red Winter Wheat (SRWW), or Hard Red Spring Wheat (HRSW). During the wheat production season Texas producers planted 5.6 million acres of wheat according to the National Agricultural Statistics Service (NASS). Projected Texas wheat production is estimated at 52 million bushels with an average yield of 26 bu/ac. The production and yield was down significantly from 2010 due to the exceptional drought that most of the state experienced during the growing season. The purpose of this publication is to provide unbiased yield data for wheat producers across the state. Using this information, Texas wheat producers can make an educated decision concerning the most appropriate varieties for their geographic region. Variety Selection: Selection of small grain varieties is one of the most important decisions a producer will make. This decision impacts potential yield (forage and grain), seed quality (test weight and protein), disease and insect management, and maturity. It is important that producers diversify the varieties to be planted on their farms. Variety diversification spreads the risk associated with potentially devastating pests (rust, Hessian fly, leaf curl mite, greenbugs, etc.) and yield loss from adverse environmental factors (freeze, drought, etc.). Producers should select no fewer than 2 or 3 varieties to plant on their farms and preferably more, depending on size and location of fields. Variety selection should be based upon a combination of sound data from university trials, and other reliable sources. Wheat varieties should be chosen based on multiple years of data (yield, pest resistance, grain quality and maturity). High yields over multiple years and multiple locations demonstrate a variety s ability to perform well over diverse environmental conditions. Stable yield performance is the best variety selection tool. It is important to consider decreasing yields over a 2 or 3 year time frame, which may reflect a change in disease and/or insect resistance. When selecting a variety for the season, producers need to consider multiple year averages, recognizing the unusual climatic conditions that impacted yield and quality over the past several years. It is strongly encouraged that producers look at the 3-year averages, and to look at numerous relevant variety trial locations. There are typically 20+ wheat variety trials conducted across the state each year, and most of these contain analyses for multiple years. 1

6 Interpreting the Data: Yield and test weight at each location have been statistically analyzed using the recommended procedures. The statistical analysis provides the mean, coefficient of variation (CV), and LSD values. It is important to note these statistical values to prevent misinterpretation of the data. The mean is another term for the average. Therefore, a mean yield is the average of all the plots within a trial. The CV value, expressed at a percentage, indicates the level of unexplained variability present within the trial. A high CV value indicates a lot of variability existed within the trial not related to normal variations that might be expected between the varieties in the test. This variability may be the result from non-uniform stands, non-uniform insect or disease pressure, variability in harvesting, or other issues. High CV values indicate a great deal of variation due to factors other than the genetic variation between varieties. CV values in excess of 15% should cause the person using the data to understand that there were problems in the trial that will cause concerns about the validity of the data as a true representation of varietal performance. The LSD value is a numeric range to help the reader determine if the varieties performed differently from one another within the trial. If the LSD value is 5 bu/ac in a trial in which Variety A yielded 36 bu/a and Variety B yielded 30 bu/a, then Variety A is said to be significantly better. In a trial with an LSD value of 5 bu/ac at a 0.05 (or 5%) level the statistical inference is that Variety A would yield better than Variety B in 19 out of 20 trials conducted in which there was a 5 bushel difference in yield. In this hypothetical comparison, you might have a 20 th trial with a 5 bu/ac difference that there is not truly a difference between Variety A and B, but random chance caused the 5 bushel difference. 2

8 2011 Texas Wheat Region Overview Texas Blacklands: The Texas Blacklands this past growing season gave many challenges to wheat producers. Most of which occurred during the grain filling with inconsistent rainfall from March to May. Yields were lower than expected for all varieties tested within this region. In addition to the drought conditions, freezing temperatures on February 3-4 set the wheat back and could have also played a role in the overall yield reduction. Texas High Plains: Unfortunately 2011 will go down as one of the driest years on record for the region. Much of the dryland wheat acreage throughout the area was not harvested due to drought. Those that were harvested were generally planted late and on land fallowed in Irrigated yields were also down. Many producers had to quit watering wheat early in order to concentrate their irrigation water on establishing corn or cotton. Insect infestation and disease infection were low throughout most of the region, although wheat streak mosaic and barley yellow dwarf could be found in some fields. A few low lying fields in the southwest panhandle were damaged from freeze injury during flowering. In isolated cases freeze damage was severe. Irrigated Trials Variety trials were planted and harvested at six irrigated locations around the Texas Panhandle and at the New Mexico State University station near Clovis. Even though trials were irrigated, yields were lower than normal due to drought conditions, hot air temperatures during flowering and late freeze damage in a few of the trials. Highest average yields were recorded in the Dimmitt trial. Three varieties, TAM 112, Winterhawk, and TAM 113 yielded in the top 25% of five of the six locations. This is only the second year we have had Winterhawk, a Westbred variety, in our trials. TAM 113 was released this year by Texas AgriLife Research and will not be commercially available until Other top varieties were TAM 111, OKO7209 (OSU experimental), Duster and Bill Brown. Other varieties of note were Hatcher and the Texas AgriLife experimental TX05A Dryland Trials Surprisingly, in spite of the drought, we were able to harvest seven of the nine dryland trials planted. Lowest average yield (12.1 bushels) was at Etter and the highest average yield (34.7 bushels) was at the Groom location. All of the dryland locations were located on fallowed land. Those locations in the eastern part of the Panhandle (Groom, Silverton, Perryton) yielded the highest, greatly benefiting from a late fall rain event. Varieties yielding in the top 25% in at least 4 of the 7 locations were TAM 113, TAM 112, OKO7209 (OSU experimental), Armour, Winterhawk and Texas AgriLife experimental TX05A Other varieties of note were Hatcher, AP 503 CL, OK07214 (OSU experimental), TAM 111, Duster and Mace. Mace is a Nebraska variety with good wheat streak mosaic tolerance. This is the second year it has been in our trials and overall its yield has been average. 4

9 Texas Rolling Plains: A severe drought was observed in the Texas Rolling Plains this year with numerous wildfires. Wheat fields planted in this region were planted dry with the anticipation of getting a rain. Yields were much lower than normal and if the wheat was not under irrigation, yields were extremely poor if it was harvested at all. In addition to the lack of moisture, high temperatures at grain fill also contributed to poor wheat yields. South Texas: Wheat producers in South Texas, like the rest of the state, had extremely dry conditions. Below normal rainfall was persistent throughout the entire growing season. Poor stands developed in dryland fields, leading to fewer harvested acres than expected. Wheat that was planted in September for fall forage performed respectively due to early rainfalls and subsequent crop establishment. 5

10 Wheat Survey Provides Important Feedback This fall wheat producers across the state participated in a Wheat Management Survey funded in part by the Texas Wheat Producers Board. The survey was designed to gather information about planting practices, management decisions and variety selection. The results of this survey will be used throughout the year to gauge priority areas for the Texas Wheat Producers Board as well as Texas AgriLife Extension and Research.
