Ok Corral
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.
Grain yield (bu/ac) in the 2019 Oklahoma Elite Trial (OET2) containing 38 experimantals and 2 check varieties.
