Genetic analysis and molecular mapping of wheat genes conferring resistance to the wheat stripe rust and barley stripe rust pathogens.
ABSTRACT Stripe rust is one of the most important diseases of wheat and barley worldwide. On wheat it is caused by Puccinia striiformis f. sp. tritici and on barley by P. striiformis f. sp. hordei Most wheat genotypes are resistant to P. striiformis f. sp. hordei and most barley genotypes are resistant to P. striiformis f. sp. tritici. To determine the genetics of resistance in wheat to P. stri...
متن کاملEvaluation of Dasypyrum villosum Populations for Resistance to Cereal Eyespot and Stripe Rust Pathogens
Dasypyrum villosum Candargy (syn. Haynaldia villosa) is a cross-pollinating, diploid (2n = 2x = 14) annual species that belongs to the tribe Triticeae (18). It is native to Southern Europe and West Asia, especially the Caucasuses (14), and grows under conditions unfavorable to most cultivated crops. The genome of D. villosum, designated V by Sears (40), is considered an important donor of genes...
متن کاملInheritance and molecular mapping of barley genes conferring resistance to wheat stripe rust.
ABSTRACT Most barley cultivars are resistant to stripe rust of wheat that is caused by Puccinia striiformis f. sp. tritici. The barley cv. Steptoe is susceptible to all identified races of P. striiformis f. sp. hordei (PSH), the barley stripe rust pathogen, but is resistant to most P. striiformis f. sp. tritici races. To determine inheritance of the Steptoe resistance to P. striiformis f. sp. t...
متن کاملMolecular and cytogenetic identification of new wheat-Dasypyrum breviaristatum additions conferring resistance to stem rust and powdery mildew
Two cytologically stable wheat-Dasypyrum breviarisatatum addition lines, Y93-1-6-6 and Y93-1-A6-4, were identified by integrated molecular and cytogenetic techniques. C-banding and genomic in situ hybridization (GISH) showed that Y93-1-6-6 and Y93-1-A6-4 were different wheat-D. breviaristatum additions. A total of 51 markers (primer/enzyme combinations), including 6 PCR-based Landmark Unique Ge...
متن کاملPhysical Localization of a Locus from Agropyron cristatum Conferring Resistance to Stripe Rust in Common Wheat
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive diseases of wheat (Triticum aestivum L.) worldwide. Agropyron cristatum (L.) Gaertn. (2n = 28, PPPP), one of the wild relatives of wheat, exhibits resistance to stripe rust. In this study, wheat-A. cristatum 6P disomic addition line 4844-12 also exhibited resistance to stripe rust. To identify the s...
