Novel complementary genes for adult plant leaf rust resistance in a wheat stock carrying the 1BL-1RS translocation
Plant Breeding 118 (3), 269-271
Abstract: The wheat–rye translocation (IBL–IRS) that carries the tightly linked genes Lr26/Sr31/Yr9, has been widely exploited in the development of wheat cultivars worldwide. This resistance, however, has become ineffective owing to the evolution of new pathotypes of Puccinia recondita that neutralize the resistance of Lr26. Inheritance studies on 'Federation*4'/'Kavkaz' revealed complementary genes derived separately from 'Federation' and 'Kavkaz' for adult plant resistance. This previously undescribed source of resistance appears to be widely effective and could therefore be used to broaden the genetic base for resistance in India. Its effectiveness in other geographical areas is unknown.
