Interpretive Summary:

Technical Abstract: Five symptom attributes (mean latent period, leaf area, relative chlorosis, relative necrosis, and mean chlorotic density) of Wheat streak mosaic virus (WSMV) infection of wheat were evaluated. Seedlings of four wheat cultivars were mechanically inoculated with WSMV strains Sidney 81 (S81) or El Batán 3 (EB3). Mock-inoculated plants served as negative controls. For all cultivars, mosaic symptoms were first apparent in plants inoculated with S81. Mean latent period (time to onset of observable mosaic) differed among cultivars for both strains, with Arapahoe
