Evaluation 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 کاملAssociation Analysis of Stem Rust Resistance in U.S. Winter Wheat
Stem rust has become a renewed threat to global wheat production after the emergence and spread of race TTKSK (also known as Ug99) and related races from Africa. To elucidate U.S. winter wheat resistance genes to stem rust, association mapping was conducted using a panel of 137 lines from cooperative U.S. winter wheat nurseries from 2008 and simple sequence repeat (SSR) and sequence tagged site...
متن کاملEvaluation of Genetic Diversity and Host Resistance to Stem Rust in USDA NSGC Durum Wheat Accessions.
The USDA-ARS National Small Grains Collection (NSGC) maintains germplasm representing global diversity of small grains and their wild relatives. To evaluate the utility of the NSGC durum wheat ( L. ssp. ) accessions, we assessed genetic diversity and linkage disequilibrium (LD) patterns in a durum core subset containing 429 lines with spring growth habit originating from 64 countries worldwide....
متن کامل16. Molecular-genetic dissection of rice nonhost resistance to wheat stem rust
Rust diseases remain a significant threat to the production of most cereals including wheat. New sources of resistance are continually sought by breeders to combat the emergence of new pathogen races. Rice is atypical in that it is an intensively grown cereal with no known rust pathogen. The resistance of rice to cereal rust diseases is referred to as nonhost resistance (NHR), a resistance mech...
