Molecular Mapping of Leaf Rust Resistance Gene Rph5 in Barley
can be easily identified and transferred into appropriate germplasm (Parlevliet, 1976). To date, 16 major raceLeaf rust caused by Puccinia hordei G. Otth is an important disease specific genes (designated as Rph1 to Rph16) for leaf of barley (Hordeum vulgare L.) in many regions of the world. Yield losses up to 32% have been reported in susceptible cultivars. The rust resistance have been identi...
متن کاملIdentification of genetic resources of field resistance to barley leaf rust in local germplasm of cultivated barley
The barley leaf rust has been important in recent years in Iran. In order to identify the genetic resources of resistance to this disease, 207 Iranian barley landraces were studied. The germplasms were investigated at the field of Iraqi-Mahalleh research station in Gorgan as the disease hotspot under natural incidence over three years. The results showed that four genotypes including KC18638 an...
متن کاملMolecular mapping of the leaf rust resistance gene Rph7 in barley
Leaf rust of barley, caused by Puccinia hordei Otth, is an important foliar disease in most temperate regions of the world. Sixteen major leaf rust resistance (Rph) genes have been described from barley, but only a few have been mapped. The leaf rust resistance gene Rph7 was ®rst described from the cultivar `Cebada Capa' and has proven eective in Europe. Previously mapped restriction fragment ...
متن کاملMolecular Markers for Leaf Rust Resistance Gene Lr42 in Wheat
Wheat leaf rust, caused by Puccinia triticina Eriks., is an important wheat (Triticum aestivum L.) foliar disease worldwide. Growing cultivars incorporating genetic resistance is one of the most effective approaches for disease control. Leaf rust resistance gene Lr42 was identified from a wheat relative, Aegilops tauschii Coss. (goatgrass), and has been transferred into hard winter wheat. A pre...
متن کاملMolecular Mapping of Wheat Leaf Rust Resistance Gene Lr42
Leaf rust, caused by Puccinia triticina Eriks., is an important foliar disease of wheat (Triticum aestivum L.) worldwide. Leaf rust resistance gene Lr42 from Aegilops tauschii Coss. has been used as a source of rust resistance in breeding programs. To identify molecular markers closely linked to Lr42, a segregating population of nearisogenic lines contrasting for the presence of Lr42 was develo...
