‘Brundage 96’ (Reg. no. CV-929, PI 631486) is a soft white winter wheat (Triticum aestivum L.) cultivar developed by the Idaho Agricultural Experiment Station and released December 2001. Brundage 96 was released as a replacement for ‘Brundage’ (Zemetra et al., 1998) in the rainfed areas of the Pacific Northwest on the basis of its high grain yield potential, end-use quality, and improved stripe rust (caused by Puccinia striiformis Westend.) resistance. Brundage 96 is adapted to the intermediate to high rainfall areas of the Pacific Northwest.

Brundage 96 originated from a single headrow, selected for different leaf color and greater stripe rust resistance from a prebreeder seed increase field of Brundage in 1996. The pedigree of Brundage 96 and Brundage is ‘Stephens’/‘Geneva’ (Kronstad et al., 1978; Sorrells and Jensen, 1987). Brundage 96 is similar to Brundage in appearance and is an awnletted, semidwarf wheat having a dark bluegreen plant color and erect to semierect flag leaves. Glumes are white, with an oblique shoulder and obtuse peak. The kernel characteristics are similar to those of Brundage, being white, soft, ovate with a midsized germ and a middeep to deep crease.

Brundage 96 was tested as ID-B-96 in the Western Regional White Winter Wheat Nursery for 3 yr (1998–2000). In rainfed trials grown in Idaho (24 site-years), Brundage 96 had an average grain yield of 6936 kg ha^-1 compared with Stephens (6316 kg ha^-1) and Brundage (6484 kg ha^-1). In 4 yr of irrigated trials, grain yields of Brundage 96 were similar to Brundage (9289 kg ha^-1 to 9306 kg ha^-1, respectively) across 11 site-years. In the Western Regional White Winter Wheat Nursery, Brundage 96 (7592 kg ha^-1) equaled or exceeded the yield of ‘Madsen’ (Allan et al., 1989) (7480 kg ha^-1) and Stephens (74360 kg ha^-1). Brundage 96 has a grain volume weight (759 kg m^-3) similar to Stephens (753 kg m^-3) and Brundage (762 kg m^-3) in Idaho under rainfed conditions (24 site years). In irrigated trials in Idaho (11 site years), grain volume weight of Brundage 96 (768 kg m^-3) was similar to Stephens (770 kg m^-3) but less than Brundage (781 kg m^-3). In Extension Service trials in Idaho (22 site years), Oregon (15 site years), and Washington (34 site years), Brundage 96 had a similar yield compared with Stephens and Madsen. The days to anthesis of Brundage 96 [165 d of year (DOY)] is the same as Stephens (165 DOY) and is later than Brundage (162 DOY), based on four years of data in Moscow, ID.

Brundage 96 has excellent end-use quality characteristics, similar to Brundage. In four years of evaluation under rainfed conditions in Idaho (19 site years), Brundage 96 averaged 8.1% flour protein (by volume), 14.8 near-infrared hardness (NIR) value, 44.8% break flour yield (by weight), and 8.8-cm sugar snap cookie diameter compared with 8.0% flour protein, 15.7 NIR hardness value, 43.4% break flour yield, and 8.9-cm cookie diameter for Brundage. Results were similar under irrigated conditions (11 site years) with Brundage 96 averaging 9.2% flour protein, 14.5 NIR hardness value, 43.5% break flour yield, and 8.8-cm sugar snap cookie diameter in comparison with Brundage, which averaged 9.1% flour protein, 17.1 NIR hardness value, 41.4% break flour yield, and 8.8-cm cookie diameter. In 3 yr of testing in the Western Regional Uniform Soft Winter Wheat Nursery (1998–2000), composite samples of Brundage 96 were equal or superior to Stephens for flour protein (8.3 vs. 8.6%), NIR hardness value (20 vs. 23), break flour yield (50.9 vs. 46.4%), flour yield (68.8 vs. 68.1%), flour ash (0.39 vs. 0.39%), sugar snap cookie diameter (9.4 vs. 9.3 cm), and sponge cake volume (1247 vs. 1160 cm³). Brundage 96 was evaluated by the Pacific Northwest Quality Council in 2001 and found to have acceptable quality for a soft white winter wheat.

Brundage 96 has greater adult plant resistance to the prevalent Pacific Northwest races of stripe rust than Brundage. In 4 yr of testing (1998–2001) in the Western Regional Soft Winter Wheat Nursery at Mt. Vernon, WA, percentage stripe rust infection on Brundage 96 ranged from 10 to 20%, whereas the percentage infection on Brundage ranged from 80 to 99%. Brundage 96 is similar to Brundage, being susceptible to cephalosporium stripe (caused by Hymenula cerealis Ellis & Everh.), strawbreaker foot rot [caused by Pseudocercosporella herpotrichoides (Fron) Deighton], septoria tritici blotch (caused by Septoria tritici Roberge in Desmaz.), common bunt [caused by Tilletia tritici (Bjerk.) G. Wint. in Rabenh. = Tilletia caries (DC.) Tul. & C. Tul.], and dwarf bunt (caused by T. controversa Kühn in Rabenh.). Brundage 96 will show physiological leaf spotting under cool, wet spring field conditions.

Breeder and Foundation seed of Brundage 96 is maintained by the Idaho Foundation Seed Program under the direction of the Idaho Agricultural Experiment Station, University of Idaho, Moscow, ID 83844. U.S. Plant Variety Protection for Brundage 96 has been approved (PVP no. 200200245).
