24 Journal of Plant Registrations, Vol 1, May–June 2007 Due to the unique amylose-free composition of Waxy-Pen starch, several end-use quality traits are dramatically altered. The following mean (± sd) end-use quality traits of ‘Alpowa’ and WaxyPen, respectively, were obtained from single replicate samples from Lamont, Lind, Pullman, St. John, and Moses Lake, WA, Western Regional Uniform Cooperative Wheat Nurseries (Alpowa was the check variety for the soft white spring WRN Coop Wheat Nurseries; Penawawa was not included): test weight, 804 (15) and 767 (13) kg m−3; Single Kernel Characterization System kernel hardness, 34 (3) and 36 (5); wheat protein, 124 (9) and 128 (11) g kg−1; L-DOPA polyphenol oxidase activity (Anderson and Morris 2001), 1.17 (0.10) and 1.20 (0.23) A475; fl our yield, 661 (12) and 594 (18) g kg −1; break fl our yield, 505 (12) and 445 (14) g kg−1; fl our ash, 4.1 (0.2) and 5.4 (0.3) g kg−1; milling score, 78.9 (1.9) and 62.7 (3.2); fl our protein, 109 (10) and 116 (13) g kg−1; fl our swelling volume, 19.9 (0.6) and 26.5 (0.4) mL g−1; carbonate Solvent Retention Capacity (SRC), 789 (41) and 1166 (75) g kg−1; water SRC, 563 (12) and 723 (18) g kg−1; sucrose SRC, 1063 (57) and 1505 (91) g kg−1; mixograph water absorption, 558 (26) and 625 (15) g kg−1; and cookie diameter, 9.18 (0.27) and 7.72 (0.18) cm. Consequently, Waxy-Pen must be strictly segregated from other soft white wheat grain. Waxy-Pen received protection under U.S. Plant Variety Protection (PVP Certifi cate No. 200600005) and has been exclusively licensed to the WSU Research Foundation (WSU RF), 1610 N.E. Eastgate Blvd., Pullman, WA, 99163. Licensing or commercialization inquiries should be directed to the WSU RF; small quantities of seed for crossing, research, and other noncommercialization activities are available on written request from the corresponding author. It is requested that appropriate recognition be made if this cultivar contributes to research or the development of germplasm or cultivars. Genetic material of this release has been deposited in the USDA National Plant Germplasm System, where it will be available after the expiry of the Plant Variety Protection for research purposes, including development and commercialization of new cultivars.
