To hedge against weather risks, plant multiple wheat varieties from more than one maturity group. Start by planting the later maturing varieties, and finish with the earlier ones. Difference between hard and soft wheats should be weighed.
A summary of performance of selected soft red winter wheat varieties in Bailey, Texas for 2013:
USG 312O, 91.5 bushel per acre yield, 50 pounds per bushel test weight; Syngenta Coker 9553, 89.4 bushels and 59.4 pounds; AGS 2035, 88 bushels, 57.4 pounds; USG 3555, 83.3 bushels and 55 pounds; USG 3409, 81 bushels, 55.4 pounds; USG 3209, 75 bushels, 53,4 pounds; USG 3201, 72.4 bushels and 57 pounds; USG 3993, 69.2 bushels, 54.1 pounds; Terral TV8525, 67.4 and 54.5; Pioneer 25R40, 65.8 and 53.8; Terral TV8848, 65.5 and 52.5; Syngenta Harrison, 63.7 and 50.5; Pioneer 25R30, 62.4 and 55.1; Syngenta Oakes, 61.4 and 55.8; Terral TV 8861, 60.9 and 54.9; USG 3251, 60.6 and 53.4; USG 3883, 58.8 and 54.4; Terral TV8535, 58.6 and 51.7; SY 474, 54.5 and 53.9; Pioneer 25R39, 53.3, and 54.6; Syngenta Magnolia, 53.1, and 54.2. Grand Mean average is 68.4 bushels and a test weight of 54.7.
2013 SRWW Highlight Summary
- The Bailey location was planted on October 30 and harvested on June 13. Ninety five percent of the wheat did not emerge until mid -January following a general rain on December 25.
- USG 3120 and AGS 2035 are very early maturing varieties, and showed some freeze damage following the March freezes. Because they emerged so late in this location, they were at an early stage of development when they were exposed to the cold weather in March and escaped significant freeze damage. We suggest these varieties not be planted before mid– to late November this fall.
- Leaf rust infection levels were heavy across the region, and most of the varieties sustained damage from this pathogen. Stripe rust (Puccinia striiformis) infection pressure was very low, except in USG 3993.
- Bushel weights were low, likely due to a late season leaf rust infection.
- Lodging was not a serious problem with the SRWWs at the Bailey location, except in the case of USG 3209
Yield stability is the most important consideration when selecting wheat varieties to plant in northeast Texas. It is risky to make varietal choices based on one year’s results because weather conditions and disease pressures vary greatly from year to year. Therefore, performance over a number of years and locations is the best indicator of varietal stability.
