✦ Synopsis

Winter-type experimental lines from crosses of two winter-type barley cultivars with a spring-type, barley yellow dwarf (BYD) tolerant cultivar were compared in inoculated and uninoculated hill plots. Mature plants traits -winter survival, height, number of spike-bearing tillers, and biomass -were examined. The experimental lines could not be compared with the BYD tolerant parent using these diagnostic symptoms since the spring-type parent would be winterkilled. Two criteria were used to rate experimental lines for BYD tolerance: (1) nonsignificant difference between BYD-inoculated and BYD-uninoculated treatments for all traits, and (2) a BYD injury score obtained by averaging percent reduction from BYD infection for each trait.
