CSU releases Antero wheat

Colorado State University Extension (Agronomy)
A new high-yielding variety of hard white winter wheat developed by the Colorado State University wheat breeding program has been released to the Colorado Wheat Research Foundation. Named Antero in honor of one of Colorado's 54 "14ers" (mountains over 14,000 feet), the new variety has shown high yields, good drought stress tolerance, good resistance to prevalent races of stripe rust, and good test weight.
"CWRF is happy to announce we took ownership of another high quality, high yielding white wheat, Antero," said CWRF President Dan Anderson. "Antero will nicely complement the hard white winter wheat varieties Snowmass and Thunder CL which are currently on the market."
The variety was tested under experimental number CO07W245. In the CSU Uniform Variety Performance Trials in 2011 and 2012, Antero was second only the hard red winter wheat variety Byrd in yield. Test weight was 0.6 pounds above trial average. Antero was also second in the Irrigated Variety Performance Trials for 2011 and 2012.
Antero is resistant to stripe rust and moderately resistant to stem rust, and is susceptible to leaf rust and Russian wheat aphid. It has excellent milling and good baking qualities.
Antero was developed through a cross of an experimental wheat variety from Kansas and TAM 111, a hard red winter wheat variety released by Texas A & M University in 2002. The experimental line from Kansas is an unreleased hard white wheat with the varieties Trego and Betty in its pedigree. The initial cross was made in spring 2003.
Heading date on Antero is 140.5 days from Jan. 1. Plant height is 29.9 inches, coleoptile length is 67.2 millimeters, and straw strength scored 4.3 on a lodging scale of 1 to 9 with 1 = completely erect and 9 = completely flat.
Antero was available to seed growers this fall, and will be available to wheat farmers around the state in limited supply in 2013, with a greater supply available in 2014. It will be marketed under the brand PlainsGold, with other varieties such as Byrd, Hatcher, Brawl CL Plus, and Denali.
Antero may be grown and sold only as a class of certified seed by Colorado Seed Growers Association members licensed by CWRF. The foundation will obtain a certificate of plant variety protection for this new variety under the federal Plant Variety Protection Act. Royalties paid to the foundation by certified seed growers from the sale of this variety are returned to CSU to support continued wheat research and variety development.
