WSMV disease scores raw data

Lines were originally scored in 2002 for response to natural infection by WSMV at Hays, KS USA and Sidney, NE USA (Divis et al., 2006). Visual subjective assessment of the degree of chlorosis and plant stunting were used (Table 1 and footnotes). Selected lines were further evaluated in the field at the University of Nebraska Agricultural Research and Development Center, Mead, NE. In 2011 individual spikes from each line were harvested and used to seed at least 20, 1.2 m replicate rows of single plant-derived lines in September 2011 as a block surrounded by early planted wheat that served as a ‘green bridge’ for the development of WCM populations. Multiple plantings of the resistant cultivar Mace and the susceptible line Tomahawk were included as a control
