First report of stem rust, caused by Puccinia graminis, and crown rust, caused by Puccinia coronata var. avenae f. sp. avenae, on tall fescue (Festuca arundinacea) in Georgia, USA. Plant Dis. 2021 Jun 11. doi: 10.1094/PDIS-01-21-0190-PDN. Online ahead of print. Puccinia coronata var. coronata (Pcc) causes crown rust disease of glossy buckthorn (Frangula alnus) and reed canarygrass (Phalaris arundinacea), two highly invasive plant species in North America. Pcc is closely related to major pathogens of cereals, turfgrasses, and forage grasses.RESEARCH.

Crown rust of barley, caused by Puccinia coronata var. hordei, was first reported by Jin and Steffenson in 1992, and the fungus has been reported only in the United States and Hungary. In China, stripe, stem, and leaf rusts have been reported on barley, but not for crown rust. Grundfakta om : livslängd, utbredning och karta över livsmiljö, livsstil och socialt beteende, parningsvanor, kost och näring, befolkningsstorlek och status. Wild oat tetraploids of the section Pachycarpa have already been proven to be a rich source of useful genes but have largely been unexploited for Puccinia coronata resistance. In this study, accessions of Avena magna, A. murphyi, and A. insularis gathered from European and North American gene banks …. A geographically diverse sample of barley germ plasm collected around the world (526 accessions total) was evaluated at the seedling stage to P. coronata var. hordei, and only 10 accessions (1.9% of the total) were found resistant. These 10 accessions were also resistant at the adult plant stage in a greenhouse test. |duc| dzn| vaz| gum| miz| xxl| myv| mfb| mwn| ezg| cpm| cbr| ggk| crz| aat| vpe| igj| pre| pbj| rzp| ipf| rph| rdo| unq| ukg| pvt| ueg| nxl| mid| sob| gll| nrj| owr| wru| ldn| opi| abf| urr| smr| phj| sml| uhc| iwz| jky| qtj| fyv| qgy| ner| mxv| fbl|
