Interpretive Summary: Soft white club winter wheat (Triticium aestivum L. ssp. compactum) is a unique component of the wheat production in the PNW, comprising 6-10% of the wheat crop. It is valued for milling and baking functionality and marketed for export in a 20-30% blend with soft white wheat as Western White. Our goal was to develop a club wheat cultivar targeted to the traditional club wheat growing region of Central Washington, with better emergence and soil borne disease resistance than the currently grown club wheat cultivars. Pritchett is agronomically competitive with other soft wheat cultivars in the PNW, and has excellent adult plant resistance to stripe rust and resistance to Cephalosporium stripe disease combined with the desired properties for excellent soft club wheat end use quality. The excellent emergence of Pritchett from deep sowing will make this cultivar competitive in the driest wheat growing regions of WA.

Technical Abstract: Soft white club winter wheat (Triticium aestivum L. ssp. compactum) is a unique component of the wheat production in the PNW, comprising 6-10% of the wheat crop. It is valued for milling and baking functionality and marketed for export in a 20-30% blend with soft white wheat as Western White. Our goal was to develop a club wheat cultivar targeted to the traditional club wheat growing region of Central Washington, with better emergence and soil borne disease resistance than the currently grown club wheat cultivars. The bulk pedigree breeding method was used to select Pritchett club wheat from the cross: 'Chukar' (PI628641)/Bruehl' //Bruehl -1 -4'. Pritchett has significantly better grain yields and grain test weight than Bruehl, the cultivar that it is targeted to replace, over multiple locations in environments receiving less than 30cm annual precipitation. Pritchett has better milling quality, producing larger diameter cookies and greater volume sponge cake. Pritchett has a high level of adult plant resistance to stripe rust (Puccinia striiformis f. sp. tritici) but carries no known major genes for stripe rust resistance. Pritchett has moderate resistance to Cephalosporium stripe disease and to eyespot and carries the Pch1 gene for resistance. Pritchett has excellent emergence from deep sowing with coleoptile lengths averaging 95cm and carries the Rht-B1b allele for reduced plant height. Pritchett was released because of its superior agronomic productivity in the targeted region, and superior end use quality combined with resistance to multiple diseases and abiotic stress.
