Performance and Mapping of Leaf Rust Resistance Transferred to Wheat from Triticum timopheevii subsp. armeniacum.
ABSTRACT Host plant resistance is an economical and environmentally sound method of control of leaf rust caused by the fungus Puccinia triticina, which is one of the most serious diseases of wheat (Triticum aestivum) worldwide. Wild relatives of wheat, including the tetraploid T. timopheevii subsp. armeniacum, represent an important source of genes for resistance to leaf rust. The objectives of...

متن کاملCytological identification of an Aegilops variabilis chromosome carrying stripe rust resistance in wheat
Aegilops variabilis (UUSvSv), an important sources for wheat improvement, originated from chromosome doubling of a natural hybrid between Ae. umbellulata (UU) with Ae. longissima (SlSl). The Ae. variabilis karyotype was poorly characterized by fluorescent in situ hybridization (FISH). The FISH probe combination of pSc119.2, pTa71 and pTa-713 identified each of the 14 pairs of Ae. variabilis chr...
متن کاملDifferential Fertilization in the Inheritance of Stem Rust Resistance in Hybrids Involving a Common Wheat Strain Derived from Triticum Timopheevi.
ALTHOUGH genes governing many characters have been transferred between species, the inheritance of only a few of these genes has been studied in detail in their new genetic backgrounds. ALLARD and SHANDS (1954) reported that the stem rust resistance transferred from Triticum timopheeui Zhuk. to a common wheat variety C.I. 12633 was controlled in certain hybrids by duplicate dominant genes linke...
متن کاملGenetic Mapping of an Aegilops tauschii–derived Hessian Fly Resistance Gene in Common Wheat
Hessian fl y [Mayetiola destructor (Say)] is a major threat to wheat (Triticum aestivum L.) production in the eastern United States. Cultivar releases containing major Hessian fl y resistance genes have proven effective in minimizing losses caused by this pest. Nevertheless, the ephemeral nature of major gene resistance necessitates the identifi cation of novel sources of resistance. Hessian fl...
