Epidemiology and control of stripe rust [Puccinia striiformis f. sp. tritici ] on wheat
Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, is one of the most important diseases of wheat worldwide. This review presents basic and recent information on the epidemiology of stripe rust, changes in pathogen virulence and population structure, and movement of the pathogen in the United States and around the world. The impact and causes of recent epidemics in the United ...
متن کاملAssessment of Two Different Sources of Durable Resistance and Susceptible Cultivar of Wheat to Stripe Rust (Puccinia striiformis f. sp. tritici)
A study was conducted to assess the durable resistance in a near isogenic line of spring wheat (Triticum aestivalis L.), possessing resistance gene Yr-18 to some isolates (race specific resistance) of stripe rust (Puccinia striiformis f. sp. tritici), namely Thatcher Yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...
متن کاملتفکیک فاکتورهای بیماری زایی در پنج نژاد پر آزار زنگ زرد گندم (Puccinia striiformis f.sp. tritici) و شناسایی منابع مقاومت نسبت به آنها
Identifying the virulence factors of stripe rust (Puccinia striiformis f. sp. tritici) disease, awareness of numbers and identification of resistance genes in wheat breeding materials, accelerate the process of producing the resistance cultivars which are sustained against different races. To study the genetic and pathogenic and non-pathogenic spectrum of genes, five hot races of stripe rust wh...
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 کاملGenetic 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...
