Susceiptibility of perennial small grains to soilborne wheat mosaic virus and wheat spindle streak mosaic virus. Online. Plant Health Progress doi: 10.1094/PHP-2005-1130-01-BR.Interpretive Summary: An undetermined threat to perennial small grain production is infection by the soilborne viruses, Soilborne wheat mosaic virus (SBWMV) and Wheat spindle streak mosaic virus (WSSMV).  We conducted preliminary experiments to assess whether perennial wheat and rye breeding lines were susceptible to SBWMV and WSSMV, individually or when co-inoculated.  Every genotype tested was at least moderately susceptible to one or both viruses.  No symptoms were observed during the autumn, even though autumn temperatures reflected those conducive to symptom development in the spring.  Our results suggest that breeders should screen perennial small grain lines for resistance to soilborne viruses in the early stages of selection and that spring is the appropriate period for visual assessment of susceptibility.
