Frequency of Phaeosphaeria nodorum, the Sexual Stage of Stagonospora nodorum, on Winter Wheat in North Carolina.
ABSTRACT Ascocarps of Phaeosphaeria nodorum, which causes Stagonospora nodorum blotch (SNB) of wheat, have not been found by others in the eastern United States despite extensive searches. We sampled tissues from living wheat plants or wheat debris in Kinston, NC, each month except June from May to October 2003. Additional wheat samples were gathered in Kinston, Salisbury, and Plymouth, NC, in ...
متن کاملGene Flow and Sexual Reproduction in the Wheat Glume Blotch Pathogen Phaeosphaeria nodorum (Anamorph Stagonospora nodorum).
ABSTRACT Restriction fragment length polymorphisms (RFLPs) were used to characterize the genetic structures of three field populations of Phaeosphaeria nodorum from Texas, Oregon, and Switzerland. Data from seven nuclear RFLP loci were used to estimate gene diversity and genetic distances and to make indirect measures of gene flow between populations. Three of the seven RFLP loci differed signi...
متن کاملPredicting Pre-planting Risk of Stagonospora nodorum blotch in Winter Wheat Using Machine Learning Models
Pre-planting factors have been associated with the late-season severity of Stagonospora nodorum blotch (SNB), caused by the fungal pathogen Parastagonospora nodorum, in winter wheat (Triticum aestivum). The relative importance of these factors in the risk of SNB has not been determined and this knowledge can facilitate disease management decisions prior to planting of the wheat crop. In this st...
متن کاملInheritance of Resistance to Stagonospora nodorum Leaf Blotch in Kansas Winter Wheat Cultivars
Stagonospora nodorum blotch, caused by Stagonospora nodorum (Berk.) Castellani & E.G. Germano (= Septoria nodorum (Berk.) Berk. in Berk. & Broome, teleomorph: Phaeosphaeria nodorum (E. Müller) Hedjaroude) can cause serious yield and quality losses of wheat (Triticum aestivum L.) in many countries worldwide (3,14,20). Yield losses caused by this disease have been reported as high as 40% in sever...
متن کاملQTL mapping of partial resistance in winter wheat to Stagonospora nodorum blotch.
Stagonospora nodorum blotch is an important foliar and glume disease in cereals. Inheritance of resistance in wheat appears to be quantitative. To date, breeding of partially resistant cultivars has been the only effective way to combat this pathogen. The partial resistance components, namely length of incubation period, disease severity, and length of latent period, were evaluated on a populat...
