Registration of 'Epoch' hard red winter wheat

'Epoch' (Reg. no. CV-1195, PI 699379) hard red winter wheat (Triticum aestivum L.) was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in February 2021 by the developing institutions. It was selected from the cross 'Hitch'/NW03666. The pedigree of NW03666 is N94S097KS/NE93459. The cross was made in 2009. The F-1 generation was grown in Yuma, AZ, in 2010, and the F-2 to F-3 generations were advanced using the bulk breeding method at Mead, NE, in 2010-2011 to 2011-2012. In 2012-2013, single F-3-derived F-4 rows were planted for selection. From 2015 on, Epoch was tested under rainfed or irrigated conditions in single replicate trials with replicated checks (2015) and in replicated alpha lattice trials (2015-2020). There was no further selection in Epoch other than to remove off-types thereafter. Epoch was selected using both phenotypic and genomic selection for its ability to survive the winter, short stature with strong straw strength, agronomic performance under irrigation, resistance to diseases, and end-use quality. Epoch seems to be narrowly adapted to irrigated production fields in Nebraska. The name Epoch was chosen because it marks the transition of leadership in the UNL Wheat breeding project from P. Stephen Baenziger to the new wheat breeder, Katherine A. Frels; hence, it marks the end of one era and the beginning of the next.

Automated summary

'Epoch' is a hard red winter wheat developed by the Nebraska Agricultural Experiment Station and the USDA-ARS. It was released in February 2021 and selected for its winter survival, short stature with strong straw strength, agronomic performance under irrigation, disease resistance, and end-use quality. Epoch appears to be well-suited for irrigated production fields in Nebraska.
