Effects of Planting Date and Inoculation Date on Severity of Wheat Streak Mosaic in Hard Red Winter Wheat Cultivars

Abstract

Hard red winter wheat cultivars were inoculated with wheat streak mosaic virus (WSMV) in the fall or spring and then were evaluated in the spring for severity of wheat streak mosaic symptoms, detection of WSMV by enzyme-linked immunosorbent assay (ELISA), fertile tiller production, yield, and thousand kernel weight (TKW). On the basis of these parameters, seven cultivars (Century, Chisholm, Pioneer 2157, Siouxland, Tam 108, Triumph 64, and Vona) were considered susceptible when inoculated with WSMV in the fall (.)
