Identification of Leaf Rust Resistance Genes in Selected Egyptian Wheat Cultivars by Molecular Markers
Leaf rust, caused by Puccinia triticina Eriks., is a common and widespread disease of wheat (Triticum aestivum L.) in Egypt. Host resistance is the most economical, effective, and ecologically sustainable method of controlling the disease. Molecular markers help to determine leaf rust resistance genes (Lr genes). The objective of this study was to identify Lr genes in fifteen wheat cultivars fr...
متن کاملEvaluation of Levels of Non-hypersensitive Resistance in Different Spring Wheat Cultivars to Leaf Rust
Levels and components of non-hypersensitive resistance in wheat (Triticum aestivum L.) to leaf rust (Puccinia triticina) were studied at seedling and adult plant stage in green house and field conditions during 2001 at Wageningen University, The Netherlands. In seedling stage, level of non-hypersensitive resistance or partial resistance was assessed from latency period (LP), infection frequency...
متن کاملgenetic analysis of inheritance of resistance in some hexaploid wheat cultivars to 134e134a+, 174e174a + races of stripe rust
inheritance of resistance to stripe rust was studied in wheat by determining the responses of 5 hexaploid wheat cultivars and 10 f1 progenies of their diallel mating crosses, against 2 races of pathogen including 174e174a+, 134e134 a+ in completely randomized design with 3 repetitions under greenhouse conditions at tehran university.the components of resistance including latent period, infectio...
متن کاملGenetics of leaf rust resistance in spring wheat cultivars alsen and norm.
ABSTRACT Alsen is a recently released spring wheat cultivar that has been widely grown in the United States because it has resistance to Fusarium head blight and leaf rust caused by Puccinia triticina. Norm is a high yielding wheat cultivar that has been very resistant to leaf rust since it was released. Alsen and Norm were genetically examined to determine the number and identity of the leaf r...
متن کاملGenetic Analysis and Molecular Mapping of Leaf Rust Resistance Genes in the Wheat Line 5R618
Wang J., Shi L., Zhu L., Li X., Liu D. (2014): Genetic analysis and molecular mapping of leaf rust resistance genes in the wheat line 5R618. Czech J. Genet. Plant Breed., 50: 262–267. The wheat (Triticum aestivum L.) line 5R618, bred at the China Agricultural University, is resistant in the seedling stage to the majority of the current Chinese pathotypes of wheat leaf rust (Puccinia triticina)....
