Identification of Chromosomes Carrying Genes for Stem Rust Resistance in Four Varieties of Wheat1

Synopsis Lines of wheat that represent chromosome substitutions into Chinese from Hope, Thatcher, Red Egyptian, and Timstein, have been tested for resistance to a number of cultures of stem lust. Chromosomes VII and XVII from Hopt; III, XIII, and XIX from Thatcher; VI, XIII, and XX From Red Egyptian; X from Timstein; and XI from Chinese carry genes for resistance to one or more of the cultures.
