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.


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.  GrazenGrain®, GoldnGrain®

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.


A premium-quality wheat variety well suited for quality-based contracted production at a yield potential comparable to Green Hammer and Showdown.  Baker's Ann produces smaller seed than Gallagher (similar to Iba) at about one-half point higher wheat protein, and qualitatively stronger dough to the degree Wheat Quality Council has classified this variety as a good blending wheat to correct for poor strength elsewhere.  Baker's Ann exhibits very strong resistance to stripe rust across a wide geography, though resistance to leaf rust may need to be bolstered with a fungicide application.  It will fit best in the Oklahoma panhandle and north central Oklahoma, and originates from the cross, TAM 303 sister/Billings.  Owing to its Texas parentage, Baker's Ann will carry the brand of GrazenGrain® but will carve a greater reputation​ under the banner of premium quality.  GrazenGrain®, GoldnGrain® 

Significant breakthrough in Barley Yellow Dwarf protection; unexplainable leaf rust resistance.

Offers a critical yield protection advantage that could call for lower input costs.  It carries a highly effective level of dual resistance to leaf rust and stripe rust, thus often neutralizing the positive effect of a fungicide application based on trials in Oklahoma and Kansas.  Protein content has averaged about a point higher than Gallagher at a similar test weight level.  Altogether, Green Hammer is considered OSU's best offering at this time for combining disease and Hessian fly resistance, protein content (and protein quality), and test weight into one variety.  Its region of adaptation is centered on southwest, central and north central Oklahoma.  Green Hammer is a progeny of the three-way cross, OK Bullet/TAM 303 sister//Shocker.  Note that TAM 303 was one of the two parents of Bentley.  Green Hammer will be marketed under the GrazenGrain®, GoldnGrain® brand.

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.  GrazenGrain®

Will be licensed as a premium-quality wheat variety for highly desirable dual functionality in bread and tortilla manufacturing.  Its kernel size is similar to Gallagher, and test weight is at least one pound higher than Gallagher.  Protein levels exceed Gallagher by about one-half point.  Skydance also has been found to tolerate suboptimal nitrogen availability and appears to be suited for certified organic production in its normal area of adaptation, which includes southwest and central OK, but extending, albeit at greater risk, into northern OK.  Its disease package is outstanding, lacking only in barley yellow dwarf resistance (moderately susceptible).  Skydance's parentage includes a Fannin sister and Billings.  GoldnGrain®


Good wheat streak mosaic resistance; best yield / test weight / quality package with WSM-R.

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 risk 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 missing tolerance. It is very widely adapted. All of these attributes make good marketing tools when visiting with producers, millers and bakers.


Ideal blend of genetics from Duster, Billings, Eastern Europe germplasm.  Widely fit for Western plains.  Standability and short stature good for maximizing irrigated yields.  Early maturity.  Acid-soil tolerant.  Very large kernel size.  Good end-use quality at target HRW protein levels.

Features a relatively high yield ceiling in a grain-only production system, and it offers complete adaptation to a dual-purpose management system with good canopy closure at adequate seeding density, outstanding forage regeneration and grazing recovery (related to its more prostrate growth habit), and Hessian fly resistance.  It will be marketed under the GrazenGrain® brand.  Test weight is in the Endurance range, and certainly not as high as Doublestop CL Plus.   Disease resistance is broad and strong, with the possible exception of leaf rust when present before heading at the level observed in 2017.  Adaptation is very wide, extending from the Rolling Plains of Texas to central Kansas, including the Oklahoma panhandle.  Its parentage includes an OK Bullet sister and an AgriPro experimental line.  GrazenGrain®

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 stripe 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.  GrazenGrain®, GoldnGrain® 

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).  GrazenGrain®, GoldnGrain®

Doublestop CL Plus upgrade for straw strength, forage production, maturity.

Butler's Gold

High protein / functionality / test weight; suited for late planting and early harvest.

OK Corral sets a new beardless standard by offering exceptional grain yield potential with excellent bread baking quality.  Due to its wide range of optimal economic uses and wide adaptability, OK Corral is positioned throughout the southern Plains, including situations subject to moderate aluminum toxicity and soil acidity (pH greater than 4.8) and to Hessian fly infestations.

Test weight on OK Corral may be optimized in more western locations including the Texas and Oklahoma panhandles, though it is sensitive to stem rust and likely susceptible to wheat streak mosaic.

Strengths include:  Versatility from grain only to forage only; pasture establishment and grazing tolerance; and balance of dough strength/extensibility; low PPO.

Weaknesses include:  Recovery from multiple spring freezes; early, severe infections of leaf rust; and grain yield may benefit from higher seeding rate.  GrazenGrain®


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.  GrazenGrain®
