CIMMYT. 1990. p. 476-48191-013879Summary: Disomic addition lines of barley (Hordeum vulgare L.) chromosone 3, which carries the Yd2 gene, have been obtained in Chinese Spring wheat (Triticum aestivum L.) from two barley cultivars, Atlas 68 and CI 3208-4. In barley, the Yd2 gene confers resistance to the barley yellow dwarf virus (BYDV). The disomic addition lines were obtained only from the selfed progeny of monotelodisomic additions (2n=42+1+t). Substitution and recombinant lines are still under development. The disomic addition of Yd2 to wheat conferred at best a small improvement in BYDV resistance based on visual symptom scoring in one field trial.
