Genetic association of wheat stem rust resistance gene Sr12 and leaf rust resistance gene Lr27



Genetic association of wheat stem rust resistance gene Sr12 and leaf rust resistance gene Lr27



Cereal Research Communications 20(3-4): 217-220



Genes Sr12 and Lr27 conferring low reactions to Puccinia graminis tritici and Puccinia recondita tritici, respectively, in Triticum aestivum and located in chromosome 3BS, were inherited independently in crosses of Chinese Spring (Hope 3B) with Chinese Spring (Thatcher 3B) and Chinese Spring (Marquis 3B) chromosome substitution lines. Since Lr27 was distally located relative to the cetromere, Sr12 was, most likely, proximally located.
