University of Sydney Plant Breeding Institute, Cobbitty, Private Bag 11, 2570, Camden, NSW, Australia aut The inheritance and expression of leaf chlorosis associated with gene Sr2 for adult plant resistance to wheat stem rust [Elektronische Daten] [G.N. Brown] Sr2, an important source of durable resistance to the wheat stem rust pathogen, is linked with a distinctive seedling chlorosis gene sc. The expression of sc is sensitive to temperature and light. The chlorosis can be induced by inoculation with the stem rust or leaf rust pathogens and also develops on uninfected leaves of rusted plants. This chlorosis is an excellent marker for Sr2 which previously was best monitored by the appearance of pseudo-black chaff on glumes or upper stem or the expression of resistance. However, the latter are only detected late in the season on field-grown adult plants. Chlorosis was recessive in F1 hybrids, however, it segregated in a dominant manner in some F3 lines presumably due to the presence of modifying genes.
