Kasebergs' new wheat

CORVALLIS, Ore. – With the baking industry in mind, Oregon State University has developed a higher-yielding soft white winter wheat that's also resistant to the disease stripe rust.

The new cultivar is known as Kaseberg and is ideal for rain-fed and irrigated areas. In field trials, the variety thrived in a number of Pacific Northwest regions, including eastern and western Oregon, southern Idaho and south central Washington.

During two years of testing in Oregon, Kaseberg averaged 136 bushels an acre on land with high rainfall or irrigation – compared with 122 bushels for similar Oregon variety Stephens and 106 for the more recent release Tubbs 06. Under low rainfall conditions, Kaseberg averaged 91 bushels per acre versus 85 for Stephens and 81 for Tubbs 06.

The new variety also resists stripe rust, a fungal disease that can cut yields in half, said Bob Zemetra, OSU's wheat breeder.

"Stripe rust resistance was fairly stable from the 1970s to 1990s,” he said. “Now the disease is changing more frequently, so breeders have to be upgrading resistance constantly."

Kaseberg is also mildly resistant to the disease Septoria, but the cultivar shows susceptibility to strawbreaker footrot, soilborne wheat mosaic virus and crown rot.

OSU researchers developed Kaseberg to appeal to millers and bakers. For cookies and crackers, it's superior to Tubbs 06, Stephens and Madsen because it has weaker gluten and finer flour particles when milled.

"New releases need to equal and surpass the performance of previous varieties,” Zemetra said. “The bar is set higher each time. In breeding we deal with three customers: the farmer, the miller and the baker. We aim to fit the needs of all three."

The new cultivar is named after the Kaseberg family, longtime eastern Oregon wheat growers who have been major contributors to the Oregon wheat industry, held leadership roles in the Agricultural Research Foundation and the Oregon Wheat League, and have allowed OSU to use their land to develop varieties for many years.

This year, OSU is also releasing another new cultivar known as Ladd. The new soft white winter wheat cultivar is the first produced in the Pacific Northwest resistant to soilborne wheat mosaic virus.

The variety is targeted toward irrigated areas in Oregon and central Washington where the virus has recently been found to thrive. Ladd is also resistant to strawbreaker foot rot and is moderately resistant to stripe rust.

The variety is named for Sheldon Ladd, the head of OSU's Department of Crop and Soil Science from 1985 to 2000.

Creating a new variety of wheat can take more than a decade. Even after that, breeders need an additional three years to generate enough seed for farmers.

Both new varieties are open cultivar releases from Oregon State University and the Oregon Agricultural Experiment Station. Registered seed of both varieties and a small amount of certified seed of Kaseberg will be available this fall.

More than 980,000 acres of wheat were harvested in Oregon in 2011, with gross sales exceeding $520 million, according to a report by OSU Extension.

It’s not all about agriculture: Granted, Wasco County’s largest economic engine is agriculture, but another reason to go to the fair starting tomorrow through Sunday is to check out the commercial building where businesses put their best foot forward.

Visit Fourth Street: Business After Hours for The Dalles Area Chamber of Commerce will spotlight businesses on East Fourth Street, including The Dalles Art Association, Planetree Health Resource Center, and Van Valkenburgh & Grossman, Lawyers this Thursday, Aug. 15, from 5 to 7 p.m.

Learn more about GMOs: Sherry Kaseberg, part of a family of long-time wheat ranchers, has been posting information about Genetically Modified Organisms (GMOs) as part of her “Sherman County eNews” email blasts. One of her most recent posts included links to documentaries on the David vs. Monsanto, Round-Up case she considers “a must watch”:

• Monsanto: A Documentary on GMO:• Dr. Mercola Interviews Dr. Huber about GMO“Genetically modified (GMO) wheat found in Oregon inspired me to learn more about genetic engineering (GE) compared to developing wheat varieties the old-fashioned way, in trial plots, over many years, a process with which I am very familiar,” Kaseberg said. “I posted the GMO wheat story in Sherman County eNews as it developed. eNews subscribers interested in the GMO issues are sending links and articles, the latest being the video links. I still have questions.”

Kaseberg hopes to talk to the wheat breeders who have developed the new “Kaseberg” wheat variety, named after Sherry and her husband Larry Kaseberg’s family for their involvement with Oregon State University and OSU Ag, providing space for elite yield trials and graduate student experimental plots, hosting USU ag students and scientist groups on field trips. The new variety has the baking industry in mind and is a higher-yielding soft winter white wheat resistant to the disease stripe rust. Find more detail online at
