Abstract
Summary Barleys with and without the Yd 2 resistance factor, wheat alien addition stocks with other barley yellow dwarf virus (BYDV) resistance factors and true wheats were challenged with three Australian isolates of BYDV‐RPV. Yd 2 resistance was effective against two of the BYDV‐RPV isolates and inoculated barleys which carry Yd 2 did not develop BYD symptoms and shoot growth was not affected. However, barleys with Yd 2 were susceptible to the third BYDV‐RPV isolate. All barley lines inoculated with the third virus isolate developed typical BYD symptoms (yellowing), shoot growth was reduced compared to uninfected controls and virus titres determined by ELISA were high and similar in barleys with and without Yd 2 . In contrast, resistances from Thinopyrum intermedium and Agropyron pulcherrimum in wheat backgrounds were effective against all three BYDV‐RPV isolates. Shoot growth of inoculated plants with either of these resistance factors did not differ from uninfected controls and virus titres determined by ELISA were very low.
