6 ARKANSAS WHEAT CULTIVAR PERFORMANCE TESTS R.E. Mason 2, R.G. Miller 2, J.P. Kelley 2, and E.A. Milus 3 INTRODUCTION Wheat cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for small-grain producers. The tests are conducted at the Northeast Research and Extension Center at Keiser, the Vegetable Substation near Kibler, the Lon Mann Cotton Research Station near Marianna, the Southeast Branch Station near Rohwer, and the Rice Research and Extension Center near Stuttgart. This year the Newport test was conducted at the Newport Research Station. Two wheat tests were planted at Stuttgart. The Standard Input Wheat Test and the High Input Wheat Test contained the same entries and were treated identically with respect to cultural practices except the High Input Test received more topdress nitrogen. This dual approach is utilized to give information on cultivar performance under conventional and high input production strategies employed by Arkansas farmers. Specific location and cultural practice information accompanies each table. METHODS Each wheat test contained 83 entries. A randomized complete block experimental design with four replications was used for all tests. A seeding rate of 105 lb/a was used to establish plots 20 feet in length and 49 inches in width (7 rows, 7 inches apart). The tests at Keiser and Rohwer were planted using a grain drill with 9 rows, 7 inches apart. Due to the larger area planted (plot width) the effective seeding rate was reduced to 82 lb/a. All sites used conventional seedbed preparation, with the exception of Rohwer where raised beds were used. Plots were end-trimmed, and harvested with a plot combine. Characters Evaluated Yield: Yields were calculated from the weight of seed from each plot as measured by the Harvest Master Pro 4100 and are expressed as bushels per acre at 13.0% moisture content. Test weight: Test weights, expressed in pounds per bushel (lb/bu), were determined using the Harvest Master Pro Lodging: Lodging is reported as an estimated percentage of plants prostrate at maturity: 10 = 10% lodged; 100 = 100% lodged. The lodging ratings are usually taken at harvest, so many of the earlier maturing lines may have higher ratings resulting from a delay in harvest. Also, high lodging scores are sometimes directly associated with more seeds per head or high grain yields. Heading Date: Heading dates are reported as the day of year that an estimated 50% of the heads had emerged. Maturity Date: Maturity dates are reported as the day an estimated 90% of the culms were yellow. Disease Ratings: Disease infections are rated visually based on the percentage of leaf or glume area displaying symptoms on a whole plot basis.

7 Arkansas Wheat Cultivar Performance Tests WEATHER SUMMARY Soil moisture was generally normal to wet prior to planting with most locations experiencing timely rain following planting. With the exception of Rohwer, fall rainfall totals were above normal for most locations, especially for the months of November and December. A mild winter with above normal temperatures led to early flowering and a dry spring resulted in early maturity. Overall, most locations experienced moderate to severe water deficits across the growing season, resulting in average yields. RESULTS Grain yields ranged from average to good across locations (Table 1). The highest average yield was recorded in Rohwer (89.7 bu/a) and the lowest was recorded in Kibler (55.9 bu/a). No difference was observed between the standard and high input tests in Stuttgart likely due to both the low yield potential and low disease pressure in this location. Stripe rust was present in four locations (Keiser, Kibler, Marianna and Rohwer), leaf rust in two locations (Keiser and Rohwer) and Septoria Leaf Blotch in three locations (Keiser, Kibler and Stuttgart). Ratings at various locations were taken by Gene Milus, Cliff Coker, and Esten Mason. The standard input test at Newport was not harvested due to stand variability. 5
