Registration of ‘Snowmass’ Wheat

Abstract

‘Snowmass’ (Reg. No. CV‐1050, PI 658597) hard white winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released in July 2009 through a marketing agreement with the Colorado Wheat Research Foundation. In addition to researchers at Colorado State University (CSU) and Kansas State University (KSU), USDA‐ARS researchers at Manhattan, KS, St. Paul, MN, and Pullman, WA, participated in its development. Snowmass was selected from the cross KS96HW94//‘Trego’/CO960293 made in 1999 at Fort Collins, CO, with the initial F1 between Trego and CO960293 made by KSU at Hays, KS. KS96HW94 is an unreleased experimental line from KSU with the pedigree ‘Arlin’ (PI 564246)/KS89H20. Trego is a hard white winter wheat cultivar released by KSU in 1999. CO960293 is an unreleased experimental line from CSU from which the germplasm release CO960293–2 was selected. Snowmass was selected as an F6:7 line in July 2006 and assigned experimental line number CO03W054–2. Snowmass was released because of its superior grain yield under nonirrigated production conditions in eastern Colorado; its resistance to Wheat streak mosaic virus, stripe rust (Puccinia striiformis f. sp. tritici), and stem rust (P. graminis f. sp. tritici); and its superior milling and bread‐baking quality.
