Interpretive Summary: End-use quality and yield potential are the most important traits for hard white winter wheat varieties produced in the Pacific Northwest region of the United States. The objective for the development of ‘Earl’ was to provide a hard white wheat variety that meets end-use quality expectations and performs well agronomically. ‘Earl’ hard white winter wheat was developed and released in September 2014 by the Agricultural Research Center of Washington State University. Earl was tested under the experimental designations LasWA8061, LasWA8061-75, and WA 8184, which were assigned through progressive generations of advancement. Earl is a semi-dwarf variety adapted for intermediate to high rainfall (>400 mm of average annual precipitation), unirrigated wheat production regions of Washington. Earl has high-temperature, adult-plant resistance to stripe rust, above average grain protein content, and high grain volume weight with end-use quality properties similar or superior to those of hard red winter wheat varieties ‘Bauermeister’, ‘Finley’, and ‘Whetstone’ currently grown in the region.

Technical Abstract: End-use quality and yield potential are the most important traits for hard white winter wheat cultivars produced in the Pacific Northwest region of the United States. The objective for the development of ‘Earl’ was to provide a hard white wheat cultivar that meets end-use quality expectations and performs well agronomically. ‘Earl’ (Reg. No. CV-xxxx, PI xxxxxx) hard white winter wheat (Triticum aestivum L.) was developed and released in September 2014 by the Agricultural Research Center of Washington State University. Earl was tested under the experimental designations LasWA8061, LasWA8061-75, and WA 8184, which were assigned through progressive generations of advancement.
