Abstract

‘UI Darwin’ (Reg. No. CV-1022, PI 639953) is a hard white winter wheat (Triticum aestivum L.) developed by the Idaho Agricultural Experiment Station and released in February 2006. UI Darwin (pedigree IDO445/‘Manning’) was tested under the experimental numbers A93151W-85 and IDO604. It is a tall semidwarf wheat released for crop-fallow rotations of the Intermountain West, where few hard white wheat cultivars are available. UI Darwin has improved resistance to stripe rust (Puccinia striiformis Westend.) relative to ‘Bonneville’ hard red winter wheat with resistance to dwarf bunt (Tilletia controversa Kühn in Rabenh) at similar levels to Bonneville. In 16 rainfed yield trials grown in Idaho from 2001 to 2005, UI Darwin had an average grain yield of 3200 kg ha-1, similar to Bonneville (3050 kg ha-1) and ‘Weston’ (3190 kg ha-1) but less than ‘Gary’ (3560 kg ha-1 UI Darwin has improved bread baking quality compared with current hard white winter wheat cultivars and has excellent color in akaline noodle products. UI Darwin had an average pup-loaf volume of 1075 mL, similar to hard red winter wheat cultivars Bonneville (1044 mL) and Weston (1064 mL) but greater than the hard white wheat cultivar Gary (963 mL).
