Molecular Characterization of Slow Leaf-Rusting Resistance in Wheat
been widely used to characterize foliar disease resistance (Jeger and Viljanen-Rollinson, 2001) because it Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gainreflects both severity and rate of disease development ing acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously (Wilcoxson et al., 1975). IR and I...
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 کاملSeedling Resistance to Stem Rust and Molecular Marker Analysis of Resistance Genes in Wheat Cultivars of Yunnan, China
Stem rust is one of the most potentially harmful wheat diseases, but has been effectively controlled in China since 1970s. However, the interest in breeding wheat with durable resistance to stem rust has been renewed with the emergence of Ug99 (TTKSK) virulent to the widely used resistance gene Sr31, and by which the wheat stem rust was controlled for 40 years in wheat production area worldwide...
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 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...
