Genetics 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 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 کاملEffect of yellow rust disease on agronomic and physiological characteristics of winter and facultative bread wheat (Triticum aestivum L.) cultivars
To investigate the effect of yellow rust disease on some agronomic and physiological characteristics of bread wheat cultivars, two field experiments were conducted in Agricultural Research Station of Miandoab in West Azerbaijan, Iran, in 2013-2014 and 2014-2015 cropping seasons. Experimental treatments were arranged as factorial in randomized complete block design with three replications. Treat...
متن کاملIdentification 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 کاملLeaf rust (Puccinia triticina) resistance in wheat (Triticum aestivum) cultivars grown in Northern Europe 1992-2002.
Diversity of resistance to leaf rust caused by Puccinia triticina can be enhanced in wheat (Triticum aestivum) cultivars through a better knowledge of resistance genes that are present in important cultivars and germplasm. Multi-pathotype tests on 84 wheat cultivars grown in Denmark, Finland, Norway and Sweden during 1992-2002 and 39 differential testers enabled the postulation of nine known ge...
