Description: ‘Oklee’ is a hard red spring wheat (Triticum aestivum L.) (Reg. no. CV-963, PI 634553) developed and released by the Minnesota Agricultural Experiment Station in cooperation with USDA-ARS in January 2003. It was named after a town in its region of adaptation in northwest Minnesota. Oklee was released on the basis of its high grain yield, high grain volume weight, high grain protein content, and early maturity. In addition, Oklee has moderate resistance to Fusarium head blight (FHB, caused primarily by Fusarium graminearum Schwabe). Oklee has erect juvenile plant growth, a recurved flag leaf, white glumes with an apiculate shoulder, and an acuminate beak. The spike is awned, mid-dense, and tapering. The kernel is red and ovate in shape with angular cheeks and a narrow, mid-deep crease. The brush on the kernel has a collar and is medium in length. Creation: Oklee was derived from the cross ‘2375’/SBF0670, made by the former Pioneer Hi-Bred spring wheat breeding program in the USA. The cultivar 2375 (PI 601477, syn. Pioneer 2375) has the pedigree Olaf//Era/Suqamuxi 68/3/Chris/ND487//Lark and was widely grown in Minnesota during the mid-1990s due to its moderate resistance to FHB. SBF0670 is an unreleased line whose pedigree contains hard red spring lines once prominent in the region including ‘Chris’ (CItr 13751, Heiner and Johnston, 1967), ‘Era’ (CItr 13986, Heiner and McVey, 1971), and ‘Butte’.
