RL6137, a ‘Thatcher’ backcross line of wheat (Triticum aestivum L.) has resistance to Puccinia triticina (causal agent of wheat leaf rust) derived from T. monococcum. To determine the chromosome location of this resistance, RL6137 was crossed with Thatcher and F2 individual seedlings were tested for segregation of leaf rust resistance and segregation of polymorphic simple sequence repeat (SSR) ...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...

Con el fin de conocer los genes presentes en plántula y tipo resistencia planta adulta 50 genotipos trigo (Triticum aestivum L.), se hicieron evaluaciones con 12 razas roya la hoja del (Puccinia triticina E.) raza MCJ/SP invernadero campo respectivamente. Entre designados que confieren a hoja, identificaron presentes, solos o combinación. Estos fueron Lr1, 2a, 3, 3bg, 10, 13, 16, 17, 23, 26, 27...
