Title	Novel complementary genes for adult plant leaf rust resistance in a wheat stock carrying the 1BL-1RS translocation.
Journal	Plant Breeding
Year	1999
Volume	118
Pages	269-271
Author	Sawhney RN Sharma JB
Abstract	Summary: 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. The resistance, however, has become ineffective owing to the evolution of new pathotypes of Puccinia recondita that neutralize the resistance of Lr26. Inheritance studies of '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
Gene	Sr31 (Triticum)
