'SW049029104' (Reg. No. CV-1053, PI 658599) soft red winter (SRW) wheat (Triticum aestivum L.) was developed and released by the Virginia Agricultural Experiment Station in March 2009. SW049029104 was derived from the cross '38158' (PI 619052)/Pioneer variety 2552//'Roane' and was tested under the experimental number VA04W-90. SW049029104 is a broadly adapted, high-yielding, moderately short, semidwarf (Rht2) cultivar that is resistant to powdery mildew [caused by Blumeria graminis (DC.) E.O. Speer] and Fusarium head blight (caused by Fusarium graminearum Schwabe). In the 2009 USDA-ARS Uniform Southern SRW Wheat Nursery conducted at 25 locations, SW049029104 ranked first among 40 entries for grain yield (4889 kg ha -1 ) and fourth for grain volume weight (73.2 kg hL -1 ). The milling and baking qualities of SW049029104 exceeded those of 'USG 3555' and Pioneer brand 26R61. Flour softness and cookie-spread diameter of SW049029104 (61.5-64.8 g 100 g -1 and 18.39-18.48 cm) exceeded those of USG 3555 (57.9-61.1 g 100 g -1 and 18.09- 18.21 cm) and Pioneer brand 26R61 (54.5-61.1 g 100 g -1 and 18.12-18.13 cm). While flour protein concentration of SW049029104 (8.55-8.66 g 100 g -1 ) was lower than that of USG 3555 (8.88-9.10 g 100 g -1 ) and Pioneer brand 26R61 (9.65- 9.66 g 100 g -1 ), its gluten strength, assessed via lactic acid solvent retention capacity (124.7-129.7 g 100 g -1 ), exceeded that of USG 3555 (118.9-124.0 g 100 g -1 ) and Pioneer brand 26R61 (113.5-126.0 g 100 g -1 ).
