The purpose of the Ohio Wheat Performance Test is to evaluate wheat varieties, blends, brands, and breeding lines for yield, grain quality, and other important performance characteristics. This information gives wheat producers comparative information for selecting the varieties best suited for their production system and market. Varieties differ in yield potential, winter hardiness, maturity, standability, disease and insect resistance, and other agronomic characteristics. Selection should be based on performance from multiple test sites and years.

EVALUATION PROCEDURES

Each entry was evaluated at five test sites using four replications per site in a randomized complete block design. Plots consisted of 7 rows, 7.5 inches apart and 25 feet long. Participating companies specified the seeding rate used for each of their varieties. Test sites were planted within twenty-one days after the fly-free date based on soil conditions. Approximately 30 pounds of nitrogen/acre was applied at planting followed by the addition of 80-100 pounds/acre in early spring. Herbicides, insecticides, and fungicides were applied as needed. The following data were collected:

Yield is reported in bushels per acre at 13.5 percent moisture.

Test Weight is reported in lb/bushel averaged across all locations.

Seed Size is thousands of harvested seeds per pound (Ex: 15.5 = 15,500 seeds per lb.).

Lodging is the percent of plants that lean more than 45 degrees from vertical.

Plant Height is the distance from the soil surface to the top of the heads.

Heading Date was the average calendar day of the year on which 50 percent of the heads were completely emerged. Average of Wood and Pickaway locations. (Example: Day 135 = May 15.)

Powdery Mildew (PM) Varieties were evaluated for Powdery mildew at Wooster at the heading (Feekes growth stage 10.5) growth stage. Varieties were classified as Susceptible, Moderately Susceptible, Moderately Resistant, and Resistant.

Fusarium Head Blight (FHB) Varieties were evaluated in an inoculated disease screening nursery at Wooster. FHB was rated as the percentage of spikelets showing diseased symptoms. Varieties were classified as Susceptible, Moderately Susceptible, Moderately Resistant, and Resistant.

Glume Blotch (SGB) and Leaf Blotch (SLB) Varieties were evaluated for Stagonospora leaf and glume blotch in an inoculated, mist-irrigated disease screening nursery at Wooster. Both SLB and SGB severity were rated at about Feekes growth stage 11.3 as the average percent flag leaf and spike area diseased, respectively. Varieties were classified as Susceptible, Moderately Susceptible, Moderately Resistant, and Resistant.

Flour Yield is the percent flour yield from milled whole grain.

Flour Softness is the percent of fine-granular milled flour. Values higher than approximately 50 indicate kernel textures that are appropriate for soft wheat. Generally, high values are more desirable.

GROWING CONDITIONS

In fall 2020, wheat was planted at all five locations within 8 days of the fly-free date. Wheat entered dormancy in good to excellent condition. Cool temperatures and adequate moisture lead to a long grain fill period and high-yielding conditions. Harvest conditions were favorable and harvest dates average. Overall, grain test weight averaged 58.1 lb/bu (compared to an average test weight of 58.8 lb/bu in 2020). Grain yield averaged between 85.1 and 115.0 bu/acre among the five locations.

RESULTS

Results of the 2021 wheat performance test are presented in Tables 1-3. Entries in the data tables are arranged by seed source. A least significant difference (LSD) value can be used to determine if the performance of two varieties was statistically different. The yields of two varieties are expected to be significantly different 90 percent of the time if their yields differ by more than the reported LSD value. Flour yield and softness tests were performed by USDA-ARS Soft Wheat Quality Laboratory, at OARDC in Wooster, OH, Dr. Byung-Kee Baik, Director.

Test results for the 79 winter wheat varieties evaluated in 2021 are presented in Table 1. Tables 2 and 3 contain multi-year variety performance data. Depending on variety and test site, yields varied between 74.7 and 128.2 bushels per acre and test weight ranged from 55.1 to 60.3 pounds per bushel. Yield differences between test sites were due primarily to the soil drainage, weather during the grain fill period & harvest, and disease level. Variety selection should be based on disease resistance, average yield across test sites and years (Tables 2 & 3), winter hardiness, test weight and standability.

Table 4 contains susceptibility of winter wheat varieties to various diseases in Ohio. Particular emphasis should be placed on FHB as this is important in reducing vomitoxin in grain. Table 5 contains the company contact information and seed treatments used for each variety entered in the 2021 wheat performance test.
