Registration of 'Anton' Hard White Winter Wheat
Additional Document Info
Low levels of the grain enzyme polyphenol oxidase (PPO) are a necessary attribute of any newly developed hard white wheat (Triticum aestivum L.) adapted to the Great Plains. Low PPO correlates with enhanced end-use quality, including the final product color in noodle applications. Few wheats with this necessary characteristic presently are available. The objective of this study was to develop a hard winter wheat adapted to the region that possesses both low levels of grain PPO and quality characteristics that would allow its utilization in domestic bread-making applications. This goal was achieved via the development and release in December 2007 of 'Anton' (Reg. No. CV-1057, PI 651044) hard white winter wheat by the USDA-ARS and the Nebraska Agricultural Experiment Station. Anton was released primarily for its low levels of PPO. Flour-PPO levels of Anton (tested under the experimental designation NW98S097) were significantly lower than all other entries in the 2003 and 2004 USDA-ARS coordinated Northern Regional Performance nursery. Polyphenol oxidase levels of Anton in grain from the 2005 University of Nebraska cultivar performance trials were not significantly different from those of the low-PPO cultivar 'Platte' and were significantly lower than those of several additional current hard white winter wheat cultivars and breeding lines. Anton was selected from the cross WA691213-27/N86L177//Platte. Crop Science Society of America.
