Abstract
Gene Sr27, present in Acosta''s wheat (''Chinese Spring'')-rye (''Imperial'') translocation line WRT.238.5, was transferred by successive backcrosses to a genetic background susceptible to P. graminis secalis. Lines obtained this way exhibited high infection types to a synthetic hybrid between P. graminis tritici and P. graminis secalis and to several strains of scabrum rust that are putative hybrids between the 2 formae speciales. The hybrid culture had inherited the virulence on plants with Sr27 from its P. graminis secalis parent. Intervarietal crossing in P. graminis in relation to the transference of resistance from alien species to wheat is discussed.This publication has 0 references indexed in Scilit:
