Interpretive Summary: This is a paper to register a new wheat cultivar, called "Ankor." Ankor was developed by the Colorado Agricultural Experiment Station and released to seed producers in August 2002. It has resistance to Russian wheat aphid and adaptation for dryland production in eastern Colorado and the west-central Great Plains. Flour protein or ash content, milling, dough and breadmaking characteristics were similar for Ankor and Akron (a parent).

Technical Abstract: "Ankor" hard red winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released to seed producers in August 2002. Ankor was released because of its resistance to the Russian wheat aphid (RWA) and adaptation for dryland production in eastern Colorado and the west-central Great Plains. Ankor was selected from the crosses and backcrosses 'Akron'/'Halt'//4*Akron made between 1994 and 1998. Halt (PI 584505)and Akron (PI 584504) are cultivars released by Colorado State University in 1994. Ankor is resistant to stem rust, susceptible to leaf rust, and susceptible to both wheat streak mosaic virus and barley yellow dwarf virus and Hessian fly and greenbug, and resistant to RWA. Ankor was tested in 11 trial locations of the dryland Colorado during from 2001 to 2002: it (2647 kg ha-1) showed similar yield as Prairie Red (2620 kg ha-1; P>0.05) and less than Akron (2714 kg ha 1; P>0.05). Relative to its recurrent parent Akron, Ankor had higher grain volume weight (727 versus 721 kg m-3), kernel weight (24.8 versus 23.6 mg kernel-1), and percent large kernels (36.3 versus 27.5% kernels that do not pass a Tyler #7 sieve, 2.92 mm openings). Flour protein and ash contents, dough mixing properties, flour and breadmaking properties were similar for Ankor and Akron. The Colorado Agricultural Experiment Station will maintain breeder seed of Ankor. Ankor has been submitted for U.S. Plant Variety Protection under P.L. 91-577 with the certification option. Ankor was developed with financial support from Colorado Agric. Exp. Stn. Projects 795 and 646, the Colorado Wheat Administrative Committee, and the Colorado Wheat Research Foundation.
