OGI Varieties

This is the breakthrough Oklahoma farmers have been waiting for, an adapted variety for the Oklahoma panhandle with highly effective resistance to the most yield-ravaging viruses in the High Plains — wheat streak mosaic and Triticum mosaic (WSM/TM). Breakthrough is the only variety adapted to Oklahoma with a gene called Wsm1, developed from a three-way collaboration among OSU, Kansas State University, and Colorado State University. Crucial to its development was finding competitive yield and quality combined with the virus resistance. Breakthrough is like Iba in those characteristics, but far better than Iba in WSM/TM protection.

Doublestop CL+ sets high standards among Clearfield and non-Clearfield varieties alike. It is at the top of its class for yield and quality combined. Doublestop CL+ is closely related to Strad CL+, but it shows more tenacity under drought and grazing stress than Strad CL+. Doublestop CL+ and Strad CL+ have equally high protein levels and desirable baking quality.

Widely adapted from the Rolling Plains of Texas through the central wheat corridor of Oklahoma into the south-central fringe of Kansas. Green Hammer is fast to first bite and shows strong grazing tolerance, with intermediate first-hollow-stem arrival in a grazed environment. Green Hammer remains one of the few Oklahoma-adapted varieties with strong resistance to both leaf rust and stripe rust. AP Roadrunner, KS Ahearn, and AM Cartwright show similar reactions.

Widely adapted from the Green Country of Oklahoma to the High Plains of the Oklahoma and Texas panhandles. OK Corral has supplanted Duster as OSU’s long-time standard for dual-purpose capability. Its unique combination of good tolerance to low pH (tested below pH 5.0) and resistance to local Hessian fly biotypes positions OK Corral favorably throughout the central wheat corridor. A deep blend of genetics from Ukraine, K-State, Pioneer, WestBred, and OSU enables OK Corral to thrive under highly variable conditions.

Widely adapted from west Texas to central Kansas, including the Oklahoma panhandle. Showdown has a very high yield ceiling with good standability and responds well to grazing with adequate seeding density. Showdown incorporates Hessian fly resistance into a Jagger background. Recovery from grazing is excellent, though a moderately early winter dormancy release may prevent grazing past mid-March in central Oklahoma.

Strad CL+ sets high standards among Clearfield and non-Clearfield varieties alike. It is at the top of its class for yield and quality combined. Strad CL+ is closely related to Doublestop CL+, but starts faster, grows faster, and finishes a few days earlier, with higher yield potential and slightly better protection against stripe rust and leaf rust. Strad CL+ and Doublestop CL+ have equally high protein levels and desirable baking quality.

Wyatt combines exceptional yield potential with the straw strength to keep it standing through harvest.  Widely adapted across the southern and central Plains, it also brings very large kernel size, good grazing tolerance, and solid disease protection.  With strong performance across a range of environments, Wyatt gives producers the combination of yield, standability, and versatility to push production potential even further.

Stardust is the first hard white wheat variety released by OSU since OK Rising in 2008. This variety’s parentage includes OK Rising. Featuring an improved level of sprout tolerance with agronomic capabilities and yield potential comparable to some of OSU’s most popular hard red varieties, Stardust’s quality characteristics and lighter brancoat make it a strong and versatile choice for bread baking.

Consumer preference is fueling the high and increasing demand for hard white wheat. Whole grain white bread is made from hard white wheat, which allows bakers to create a whole grain product without the red color or the slightly different taste. Millers also can extract more flour from the grain of hard white wheat, thereby increasing the efficiency of the milling process.

Stardust will provide wheat producers in north central Oklahoma, in particular, the ability to produce hard white wheat locally and potentially capture more markets for Oklahoma wheat. GrazenGrain®

Contender is a large-seeded high-oleic Virginia type that has enhanced pod size distribution and seed size when compared to the Virginia-type cultivar VENUS. Released jointly by the USDA-ARS and Oklahoma Agricultural Experiment Station in 2018, Contender is the result of a cross between the high-oleic Virginia cultivar Brantley and high-oleic runner cultivar Red River Runner. Contender had an average pod yield of 5,773 lbs/acre, a grade of 69, 55% ELK, and 76% total fancy pods, giving it the highest estimated value for the producer among the Virginia-type cultivars tested in the Oklahoma Variety Trials for 2016-2017. Contender is moderately resistant to Sclerotinia blight and pod rot when compared to Jupiter.

Peanuts normally contain about 50% oil with an oleic acid to linoleic acid ratio (O/L ratio) of about 1.5:1. In 1987, Al Norden at the University of Florida discovered a spontaneous mutant line – F435 – with an O/L ratio of over 10:1. Since then, studies have revealed that high O/L ratios improve peanut shelf life up to 10 times and boost nutritional value. The first high-O/L Spanish variety, OLin, and later Tamnut OL06, became contaminated and are no longer high O/L by industry standards. OLé fills a need in the industry for a high-O/L Spanish peanut suitable for production in the Southwestern U.S.

OLé is the product of a cross made in 2000 between Tamspan 90, a Spanish variety with resistance to Sclerotinia blight and pod rot, and F435, the original donor of the high oleic gene. Third-generation seed was tested for O/L fatty acid content. Single plant selections were made at this stage on the basis of oil chemistry, seed size, agronomic characteristics, and disease resistance. Bulk selections were made at the fifth generation in 2007 from healthy, Sclerotinia-free plants, and from 2008 to 2013, seeds were increased in Oklahoma and Puerto Rico, and tested in performance trials in various locations in Oklahoma.
