Resistance Potential of Bread Wheat Genotypes Against Yellow Rust Disease Under Egyptian Climate
Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces w...
متن کاملDevelopment of yellow rust resistant doubled haploid lines of wheat through wheat ´ maize Crosses
In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...
متن کاملidentification of ssr marker linked to leaf rust resistant gene lr24 and marker assisted transfer of leaf rust resistance genes into bread wheat
a study was conducted to identify ssr markers linked to leaf rust resistance genes lr24 and lr28 and to be used for marker-assisted selection (mas) to transfer both genes to a widely cultivated wheat variety mp 3299 under rainfed condition. f2 individuals of the cross mp 3299×nil pbw 343 were used for generating genotypic data employing closely linked scar markers s73719 and s421570 to lr24 and...
متن کاملDiversity of Resistance Gene Analogues in Rust Resistance and Susceptible Bread Wheat Varieties
Fungal diseases, especially leaf and stripe rusts are wheat yield reducing factors in Iran and the world. In this study, genetic diversity of 20 wheat varieties with different response to leaf and stripe rusts were studied using primers designed based on the conserved regions of plant disease resistance genes. The banding patterns of polymorphic markers were scored as dominant and number of amp...
متن کاملeffects of yellow rust on yield of race-specific and slow rusting resistant wheat genotypes
rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
