PENDLETON, Ore. -- Oregon State University wheat breeder Bob Zemetra says several varieties in the development pipeline show promise.

Among them is a soft white winter wheat with good stripe rust resistance and good end-use quality. OR2071628, as it is known, is in foundation seed production. It could be available to growers as certified seed by the fall of 2014.

He gave a presentation to the Oregon Wheat Commission last month.

Another numbered variety that Zemetra featured is a cross between Tubbs 06, a soft white winter wheat, and Einstein, a semi-hard red wheat out of Europe. OR08047P94 has good end-use quality, he said, and is showing good resistance to stripe rust and septoria, a fungal disease common in the Willamette Valley.

"I think this has potential to be a tri-state wheat," Zemetra said. "Everywhere we have grown it, it has done well."

The Einstein-Tubbs 06 cross is in breeder-seed production and could be available as certified seed as early as 2015.

OR2070870 is another variety with good end-use quality, good yield potential and good stripe-rust resistance, Zemetra said. The variety also is showing good soil-borne wheat-mosaic-virus resistance, he said.

It could be available as certified seed in 2014, Zemetra said.

Zemetra also informed commissioners about two hard-white winter wheat varieties that have good yield potential, but had trouble meeting protein targets this year.

The two also could be available as certified seed by 2015, "if we have a market for them," he said.
