Arrowsmith/Wsm1 is a near-isogenic line carrying wheat streak mosaic virus resistant gene Wsm1. The Wsm1 gene donor was a hard red winter wheat line KS93WGRC27 (PI 583794) that carries the gene on an Agropyron intermedium (Host) P. Beauv. segment translocated to wheat chromosome 4DS. This line was backcrossed five times to Wahoo followed by subsequent selfing. Beginning with the BC1 generation, the sequence-tagged-site (STS) marker STSJ15 that is specific for the translocated segment carrying Wsm1 gene, was used to select resistant plants. At the end of the backcrossing cycles, selfed progeny of each of the BC4F2 plants were screened with the marker in order to select BC4F2 homozygous for the gene. The resistance in the selected plants was confirmed by phenotypic screening of F3 progeny using Sidney 81 strain. Morphologically the germplasm looked very similar to its recurrent parent (Arrowsmith) and no significant differences were observed for height or days to flowering. [See PI 653710-653716 for accessions from the same J Plant Registrations citation.]
