Identification of QTL conferring resistance to stripe rust (Puccinia striiformis f. sp. hordei) and leaf rust (Puccinia hordei) in barley using nested association mapping (NAM)
The biotrophic rust fungi Puccinia hordei and Puccinia striiformis are important barley pathogens with the potential to cause high yield losses through an epidemic spread. The identification of QTL conferring resistance to these pathogens is the basis for targeted breeding approaches aiming to improve stripe rust and leaf rust resistance of modern cultivars. Exploiting the allelic richness of w...
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...
متن کاملRaces of Puccinia striiformis f
Stripe rust of barley, caused by Puccinia striiformis f. sp. hordei (PSH), occurred mainly in California, Idaho, Oregon, and Washington and caused localized damage to barley crops. Growing cultivars with high-temperature, adult-plant resistance and the cropping system contributed to the low level of stripe rust. Stripe rust samples were collected from the four states and tested under controlled...
متن کاملIdentification of a quantitative trait locus for high-temperature adult-plant resistance against Puccinia striiformis f. sp. hordei in 'Bancroft' barley.
Sustainable control of plant diseases can be achieved by developing cultivars with durable resistance. 'Bancroft' barley has durable high-temperature, adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. hordei. The objectives of this study were to determine the inheritance of the HTAP resistance in Bancroft, develop molecular markers for the HTAP resistance using ...
متن کاملژنهای بیماریزائی و پاتوتیپ‌های Puccinia striiformis f. sp. hordei عامل بیماری زنگ زرد جو در چند منطقه ایران
به منظور تعیین پاتوتیپ‌های زنگ زرد جو، نمونه‌هایی از جو، جو موشی (Hordeum morinum) و گندم آلوده به زنگ زرد (Puccinia striiformis) از استان‌های مختلف ایران جمع‌آوری شد. جدایه‌ها بر اساس ایجاد آلودگی روی ارقام افتراقی زنگ زرد جو یا گندم، به ترتیب به عنوان فرم اختصاصی P. striiformis f. sp. hordei یا P. striiformis f. sp. tritici تشخیص داده شدند. ژن‌های بیماریزائی و پاتوتیپ‌های عامل بیماری زنگ ز...
