Registration of “ARS Crescent” soft white winter club wheat. Journal of Plant Registrations. 15(3):515-526. https://doi.org/10.1002/plr2.20135.
Interpretive Summary: The soft white club wheat ARS Crescent is agronomically competitive with other soft wheat cultivars in the Pacific Northwest of the United States. ARS Crescent has adult plant resistance to stripe rust, moderate resistance to soil borne diseases and tolerance to low falling numbers. The excellent end use performance of ARS Crescent improves the export value of the PNW wheat crop to Pacific Rim countries. The excellent grain yield and grain volume weight of ARS Crescent compared to existing club and common soft white wheat cultivars were the primary justifications for release and continued popularity.
Technical Abstract: Soft white club winter wheat (Triticium aestivum L. ssp. compactum) represents 8-10% of the wheat crop in Washington but most of the current club wheat production is located in the less-than 350 mm annual precipitation zone. Our goal was to develop a club wheat cultivar targeted to the greater-than 350 mm annual precipitation zones of the Pacific Northwest (PNW). ‘ARS Crescent’, an awned white-kernel club wheat, was selected using the bulk-pedigree breeding method, from the cross: 'Dusty'//'Madsen' sib/Dusty///WA7665/'Rulo'. ARS Crescent was rated as resistant to stripe rust (Puccinia striiformis Westend. f. sp. tritici Erikss.) races PSTv-4 and PSTv-51, segregating for resistance to race PSTv-37, and susceptible to races PSTv-14 and PSTv-40 in the seedling stage. ARS Crescent has demonstrated high temperature adult plant resistance. In high rainfall environments, the grain yields of ARS Crescent were significantly higher than Cara, and soft white wheat cultivars ‘ORCF102’ and ‘Xerpha’; less than ‘Bruehl’; and equivalent to soft white wheat checks. Eight years after release, ARS Crescent remains competitive with the most widely grown soft wheat cultivars. ARS Crescent has significantly better test weight than Bruehl and Cara and is resistant to environmental conditions that result in low falling numbers in wheat. ARS Crescent has excellent milling properties and greater sponge cake volume than other club wheat cultivars and increases the quality of the crop in WA.
