Relationship Between Development of Hard Red Winter Wheat and Expression of Resistance to Wheat Soilborne Mosaic Virus

(...) All three evaluations showed that resistant cultivars became infected by wheat soilborne mosaic virus, and symptoms were most pronounced during early jointing in February and March. In resistant cultivars, high ELISA values and high virus concentrations occurred later in the growing season than those in susceptible cultivars. Results form a study conducted in a growth chamber indicated that the late-season rise in ELISA values observed in resistant cultivars is related to tiller maturity rather than to sampling date
