For 2012, wheat varieties for the High Plains include:

  • TAM 111, TAM 113, Hatcher, Duster and Winterhawk for all conditions, full irrigation to dryland.
  • Specific for particular production conditions are: TAM 112 for limited irrigation and dryland – stand-ability can be an issue in full irrigation; TAM 304 for full irrigation with high inputs; and Endurance ondryland.

“When a variety is selected as a pick for all production conditions, this speaks well of that variety for its broad adaptation,” Trostle said.

TAM 113 and Winterhawk are new additions in 2012. TAM 113 has broad adaptation and improved leaf rust and stripe rust resistance compared to other varieties, Rudd said.

Winterhawk has been a top three-year yielder in both irrigated and dryland production averaged across 17 sites, but Rudd said this variety is susceptible to stem rust, to which most other varieties are resistant.

Trostle suggested that because of this, producers interested in Winterhawk should limit it to no more than 25 percent of their total acreage.

An additional means of comparing wheat performance is averaging the annual yields of pick vs. non-pick wheat varieties over time, they said.

For the three-year harvest period of 2010 to 2012, irrigated picks averaged 68.9 bushels per acre compared to 62.5 bushels per acre for non-picks, an 11 percent yield advantage, Trostle said. The same pick varieties also average 1.2 bushels per acre higher in test weight. The same comparison in dryland finds a 3.4 bushel per acre, or 10 percent increase, for dryland wheat pick varieties vs. non-picks.

Trostle said there is no surprise in these numbers.

“We would have guessed that this might be the case, but prior to 2012 we didn’t tabulate the data in this manner,” he said. “It is further evidence that producers should consider including a mix of the wheat picks as part of their wheat farming practices.”
