Interpretive Summary: ‘Ripper’ is a new hard red winter wheat developed by the Colorado Agricultural Experiment Station and released in August 2006 by the Colorado Wheat Research Foundation. Ripper was selected from the cross CO940606/TAM107R-2 and was called CO00016 before its release. It has superior grain yield under nonirrigated production in eastern Colorado and superior milling and bread-baking quality.

Technical Abstract: ‘Ripper’ (Reg. No. CV-1016, PI 644222) hard red winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released in August 2006 through an exclusive marketing agreement with the Colorado Wheat Research Foundation. In addition to researchers at Colorado State University, USDA-ARS researchers in Manhattan, KS, and St. Paul, MN, participated in the development of Ripper. Ripper was selected from the cross CO940606/TAM107R-2 made in 1996 at Fort Collins, CO. CO940606 is an unreleased sib-selection of KS94WGRC29 (PI 586954), a germplasm release from Kansas State University with the pedigree PI 220127/P5//‘TAM-200’/KS87H66, while TAM107R-2 is an unreleased sib-selection of the hard red winter wheat cultivar Prairie Red (PI 605390). Ripper was selected as an F3:4 line (F3–derived line in the F4 generation) in 2000 and assigned experimental line number CO00016. Ripper was released because of its superior grain yield performance under nonirrigated production in eastern Colorado and superior milling and bread-baking quality.
