Interpretive Summary: Jamestown’ soft red winter wheat (Triticum aestivum L.) was named in commemoration and celebration of the 400th anniversary of the founding of the first colony in Virginia in 1607. In the mid-Atlantic region, early-maturing wheat cultivars offer producers an economic advantage in double-cropping systems where a soybean [Glycine max (L.) Merr.] crop is planted immediately following wheat harvest. Earlier wheat harvest allows for earlier soybean planting, a longer growing season, and generally higher soybean yields due to more favorable moisture conditions during critical pod and bean development stages. Spike emergence of Jamestown wheat is only 4 d later than that of ‘Thoroughbred’ barley, which is currently the most widely grown winter barley cultivar in the mid-Atlantic region. Jamestown is widely adapted and provides producers from the southern Corn Belt to the Deep South and throughout the mid-Atlantic region with a distinctly early maturing, disease- and pest resistant cultivar. Capability for viable production of Jamestown throughout these diverse regions is due to its moderately good winter hardiness and its notable resistance to Hessian fly, leaf rust, stripe rust, powdery mildew, and Fusarium head blight.

Technical Abstract: ‘Jamestown’ (Reg. No. CV-1041, PI 653731) soft red winter wheat (Triticum aestivum L.) was developed and released by the Virginia Agricultural Experiment Station in March 2007. Jamestown was derived from the cross ‘Roane’/Pioneer Brand ‘2691’ and was tested under the experimental number VA02W-370. Jamestown is an early heading, awned, short-stature, semidwarf (Rht2) cultivar possessing resistance to the predominant insect and disease pests in the eastern soft wheat region. Jamestown most notably has resistance to Hessian fl y [Mayetiola destructor (Say)], stripe rust (caused by Puccinia striiformis Westend.), and Fusarium head blight [caused by Fusarium graminearum (Schwabe)]. In USDA–ARS Uniform Southern Soft Red Winter Wheat Nursery Trials conducted at 27 locations in 2005 and at 26 locations in 2006, Jamestown produced average grain yields of 5496 and 5563 kg ha–1, respectively, compared with nursery mean yields of 4959 kg ha–1 in 2005 and 4878 kg ha–1 in 2006. Milling and baking quality of Jamestown exceeds that of ‘USG 3209’. On an Allis Chalmers Mill, Jamestown has higher break fl our yield (305 vs. 283 g kg–1), softer fl our texture (softness equivalent score 57.4 vs. 54.1 g 100 g–1), lower sucrose solvent retention capacity (93.8 vs. 104 g 100 g–1), and larger cookie diameters (17.0 vs. 16.8 cm).
