Interpretive Summary: 'Masami’ soft white winter wheat (Triticum aestivum L.) (Reg. no. CV- , PI 634715) was developed by the Agricultural Research Center of Washington State University (WSU) in cooperation with the USDA-ARS. Masami was jointly released by Washington and Idaho Agricultural Experiment Stations and the USDA-ARS in 2004. Masami is targeted for the low- to intermediate-rainfall (<460 mm average annual precipitation) wheat production regions of Washington State. It was released for its excellent grain yield, cold hardiness, end-use quality and disease resistance. Masami is named in honor of Masami “Dick” Nagamitsu, a retired WSU wheat researcher.

Technical Abstract: 'Masami' soft white winter wheat (Triticum aestivum L.) (Reg. no. CV- , PI 634715) was developed by the Agricultural Research Center of Washington State University (WSU) in cooperation with the USDA-ARS. Masami was jointly released by Washington and Idaho Agricultural Experiment Stations and the USDA-ARS in 2004. Masami is targeted for the low- to intermediate-rainfall (<460 mm average annual precipitation) wheat production regions of Washington State. It was released for its excellent grain yield, cold hardiness, end-use quality and disease resistance. Masami has eyespot and stripe rust resistance similar to ‘Madsen’ (PI 511673). It also has shown resistance to leaf rust (caused by Puccinia recondita Rob. ex Des.) and powdery mildew [caused by Blumeria graminis (DC.) Golovin ex Speer (syn. Erysiphe graminis DC.) f. sp. tritici Em Marchal]. Masami expresses moderate resistance to Cephalosporium stripe (caused by Cephalosporium gramineum Nis. & Ika.) and dwarf bunt (caused by Tilletia controversa Kühn). Masami typically shows physiological leaf spotting under cool, wet spring field conditions. Masami is named in honor of Masami “Dick” Nagamitsu, a retired WSU wheat researcher.
