Abstract

‘Arrowsmith’ (Reg. no. CV-969, PI 633911) hard white winter wheat (Triticum aestivum L.) was developed cooperatively by USDA-ARS, the Nebraska Agricultural Experiment Station, and the Wyoming Agricultural Experiment Station. Arrowsmith is adapted to dryland environments in western Nebraska and eastern Wyoming. It was released on the basis of its white grain color, medium-long coleoptile length, and tall plant height, all desirable features for wheat grown on dryland sites in the Nebraska Panhandle and eastern Wyoming.

Arrowsmith was derived from the cross KS87809-10/‘Arapahoe’, made in 1993. KS87809-10 is an experimental hard winter wheat from Kansas State University with the pedigree KS831374-141B/YE1110. KS8321374-141B was a reselection out of ‘Karl’ (PI 527480), while YE1110 was descended from a cross between ‘Gerek 79’ (PI 559560), a winter wheat from Turkey, and ‘Aurora’, a winter wheat from the former Soviet Union. Arapahoe (PI 518591) is a Nebraska developed hard red winter wheat (Baenziger et al., 1989). F₁ through F₃ generations were advanced via self-pollination and maintained as bulk populations. From the F₃ generation, 100 heads were selected and planted as F₄ single-head-progeny rows. Arrowsmith originally was selected from one of these rows as an F₃–derived F4 line, and assigned the experimental number NW97S182. Breeder seed originated from a composite of 30 F₉–derived headrows which were selected for uniformity in plant type and grain color.
