Billings is a high-yielding, large-kernel hard red winter wheat variety derived from a single cross of a Ukraine variety with a Pioneer experimental. The variety combines very good stay-green characteristics with early maturity. It exhibits excellent resistance to wheat soilborne mosaic virus, leaf rust and stripe rust, as well as good protection against powdery mildew. Early dormancy release and moderate susceptibility to barley yellow dwarf virus make the variety less adapted to early planting production systems.

The variety is highly suited for irrigation production and will achieve far more grain production if planted in October and not grazed. Yields reported in breeding nursery plots exceeded expectations, extending in excess of 120 bushels per acre when the nursery average was approximately 95 bushels per acre.

Target regions for Billings include central and northwestern Oklahoma, as well as the Panhandle if irrigation is employed.


OSU’s Gallagher wheat variety boasts Duster parentage and forage production with improved yield and disease resistance. Gallagher is an early maturing variety with good grazing tolerance, and exhibits an approximate 15 percent increase in seed size over Duster. It is resistant to leaf rust and strip rust, wheat soilborne mosaic virus and wheat spindle streak mosaic virus. In addition, Gallagher is moderately resistant to tan spot and barley yellow dwarf. The variety is also septoria leaf blotch resistant for no-till and high-residue systems.

Gallagher exhibits an acid soil tolerance comparable to Duster, is Hessian fly resistant and has the ability to exceed 12 percent grain protein with adequate fertilization. It has good stay green and shattering tolerance characteristics, with above average baking and milling characteristics.

The wheat variety is well suited for Oklahoma operations, with the exception of those in the Panhandle, which is considered a secondary area of adaptation.


Released by Oklahoma State University, Iba features a broad area of adaption with proven yielding ability reflected in performance tests from Kansas to Texas. Of Duster parentage, the variety has outstanding test weight and average to above average resistance to leaf rust, stripe rust, powdery mildew and soilborne mosaic virus.

With strong resistance to the two prevalent viral diseases in north central Oklahoma, wheat soilborne mosaic and wheat spindle streak mosaic viruses, it should be positioned in that area with preference over Endurance and possibly OK Bullet. Its resistance to leaf rust remains undefeated as of May 2006, both in Oklahoma and in Texas. With added tolerance to low-pH soils, it cannot be branded with a "resistant" reaction type. Duster certainly showed resilience in grain yielding ability under those conditions in 2005. Based on preliminary yield results from 2006, Duster lost some of its competitiveness under the extreme drought conditions of 2005-2006, producing many more fertile tillers than the remnant moisture supply during the grain-filling period could support. However, it still managed to take top-yielding positions in elite breeding nurseries conducted at Altus and Ft. Cobb, OK.

Duster does not show any serious blemish for milling and baking quality, though OK Bullet should maintain its top ranking in this area. A tendency toward smaller kernel size is its primary weakness. Other relatively minor limitations include susceptibility to all biotypes of greenbug and Russian wheat aphid, and moderate susceptibility to lodging that becomes most apparent under conditions of rank vegetative growth.

The primary area of adaptation for "Garrison" includes all of Oklahoma's wheat producing areas extending southward into Texas and north into Kansas and west into the Texas High Plains. Secondary areas of adaptation may extend into northern Kansas, eastern Colorado and southern Nebraska. "Garrison" will be at rish where Hessian Fly is an issue, so it should not be planted on an area where there is a history of severe Hessian Fly infestations. "Garrison" production focus is primarily for a grain-only management systems. However, dual purpose production is possible with forage yields being limited.

"Garrison" has several very exciting attributes in which OGI is interested. It has shown a tendency to out yield Endurance, has strip rust resistance, has low pH tolerance, has test weight stability, protein content stability and good mising tolerance. It is very widely adapted. All of these attributes make good marketing tools when visiting with producers, millers and bakers.

It is a tall, semi-dwarf with an intermediate heading date (3 days later than Jagger) and a semi-erect growth habit similar to Jagger. OK Bullet is expected to have moderately good standability under conditions conducive to lodging. It has consistently been one of the highest test weight varieties in each of the nurseries tested since 2000 with an average of 60.3 lb/bu.

In lodging readings taken in areas of significant lodging problems, OK Bullet has shown no disadvantage in lodging resistance. OK Bullet has a tolerance to low pH fields similar to Ok101 and Jagger, with all three having tolerance ratings of 2 on a 1 to 5 scale. It consistently produces large kernels and has shown well in baking and milling qualities and protein content.

OK Bullet appears to be resistant to leaf rust in the adult plants, moderate resistance to stripe rust, sceptoria leaf blotch, and tan spot. It is moderately susceptible to barley yellow dwarf virus, intermediate to fusarium head blight (scab) and susceptible to powdery mildew in the adult plants.

OK Bullet appears to have more potential for grain since with continuous forage removal it has less capacity for regrowth.

The primary area of adaptation for "Ruby Lee" encompasses all of Oklahoma wheat producing areas extending southward into north Texas and north into southern Kansas and west into the Texas High Plains (with irrigation). Secondary areas of adaptation may extend into northern Kansas, eastern Colorado and southern Nebraska, but "Ruby Lee" will be at risk where strip rust and very low soil acidity area issues. "Ruby Lee" is recommended primarily for grain-only management systems. However, dual purpose system production is not discouraged as it has above-average ability to be grazed and adaptation to early-planted management systems is very characteristic of "Ruby Lee".

One of the most exciting aspects of "Ruby Lee" that statement by the breeder that it should also be the first OSU HRW cultivar to be recommended for contract production to ensure 1) direct delivery of enhanced end-use value to millers and bakers and 2) direct value capture by producers. OGI would agree with this statement after reviewing the mill, dough and bake test information. It has good mix times, long stability time at acceptable proteins. The kernels are large with good thousand kernel weights and good kernel diameter. This is a variety that will assuredly interest millers and bakers.


A hard red winter wheat, Bentley features excellent grain yielding ability under challenging climate conditions, including moderate but chronic drought stress & late winter freezes.

It also fits well in dual-purpose grazed systems and in minimum-tillage systems promoting the development of multiple leaf spotting diseases.

Bentley's drought resistance is equal to or slightly better than Iba, which is currently our best adapted variety for drought, but it has much better leaf hygiene in the presence of leaf spotting diseases, particularly tan spot & physiological leaf spot.

Bentley is best suited for growth in southwestern and central Oklahoma and areas extending north, east & possibly into south central Kansas. Its use in the panhandle should be limited to dryland conditions.

Producers should wait until early September to plant Bentley due to possible heat-sensitive germination and the variety should not be harvested late because of the potential for below-average test weight.

Consider Bentley as a genetic background complementary to what's currently available in Duster, Gallagher & Iba. It will offer competitive yield in the presence of multiple yield-limiting factors, with drought being the main factor.

Bentley was named after Walter Dimmitt Bentley, a former educator turned farmer who served as the first director of the Oklahoma Cooperative Extension Service from 1914 to 1916 and as assistant director of Extension from 1917 until his sudden death in 1930.​

Doublestop CL Plus

Doublestop CL Plus was released in 2013. The wheat variety has a wide area of adaptation, is late to first hollow stem and possesses a late maturity that is about the same as Endurance. Strengths of Doublestop CL Plus include excellent test weight with good protein content and quality; yield stability across a wide range of environments, including drought-stressed and high-yield systems; good acid soil tolerance, and good milling and baking characteristics. The variety is resistant to wheat soilborne mosaic virus but exhibits inconsistent resistance to wheat spindle streak mosaic virus. It is moderately resistant to leaf rust, stripe rust and barley yellow dwarf.

Doublestop is a two-gene Clearfield wheat variety that offers improved control of problem weeds such as feral rye and jointed goatgrass. The Clearfield system is a non-genetically modified crop herbicide tolerance technology and not a genetically modified organism (GMO). As the name implies, two-gene Clearfield wheat varieties have two copies of the gene that confers resistance to imidazolinone herbicides. Two-gene technology in wheat provides the option of adding 1 percent v/v methylated seed oil (MSO) to the spray solution (1 gallon of oil per 100 gallons of water).
