Fifty‐three commercially grown cultivars and germplasm lines of winter triticale ( n = 18), wheat 13), rye 5) spring 8), 7) 2) were inoculated at mid anthesis with a spore suspension consisting mixture Fusarium culmorum , avenaceum graminearum isolates known toxinogenic activity. Reactions to head blight measured as disease severity, reductions kernel number/head, weight/head 1000 weight, number ‐damaged kernels content deoxynivalenol (DON) its acetyl‐derivatives 3‐AcDON, 15‐AcDON,...
Stagonospora nodorum blotch is an important foliar and glume disease in cereals. Inheritance of resistance wheat appears to be quantitative. To date, breeding partially resistant cultivars has been the only effective way combat this pathogen. The partial components, namely length incubation period, severity, latent were evaluated on a population doubled haploids derived from cross between Triticum aestivum 'Liwilla' susceptible 'Begra'. Experiments conducted controlled environment fifth leaf...
Currently, European farmers do not have access to sufficient numbers and diversity of crop species/varieties. This prevents them from designing cropping systems more resilient abiotic biotic stresses. Crop diversification is a key lever reduce pest (pathogens, animal pests weeds) pressures at all spatial levels fields landscapes. In this context, plant breeding should consist of: (1) increased efforts in the development new or minor varieties foster systems, (2) focus on showing local...
The spatial and temporal patterns of discharge dissemination airborne spores Phaeosphaeria spp. Stagonospora were studied. Both ascospores pycnidiospores the pathogens deposited at various densities on microscope slides used as spore samplers. maximum deposition was observed during period August to October. A multiple regression analysis determine which weather factors significantly explained variation measured in numbers that settled slides. Rainfall, air temperature, relative humidity...
Parastagonospora nodorum leaf and glume blotch (syn. Septoria blotch, SNB) is a severe disease in many wheat-growing areas worldwide. In previous study, mapping population, Liwilla × Begra, was used to detect several resistance quantitative trait loci (QTL) at the seedling stage. this study same population analysed adult plant stage under field polytunnel conditions. After artificial inoculation severity on leaves glumes scored as progress curves for tests percentage of area covered by...
The occurrence of necrotrophic winter wheat and triticale pathogens in eight geographical regions Poland was studied between 2015 2020. Over a period six years, the incidence following monitored: Parastagonospora nodorum, avenae Zymoseptoria tritici. significant effect meteorological factors on determined. relationship late-season early-season associated with temperature precipitation severity diseases incited by statistically significant. Statistical models estimating natural caused were...
Abstract Thirty‐six isolates of Stagonospora avenae f. sp. triticea , S. nodorum and Septoria tritici recovered from asexual fruiting bodies ‐ pycnidia their spores were assessed for DNA polymorphism with the use three molecular techniques: microsatellite‐primed polymerase chain reaction (MP‐PCR), primers correspond to dispersed repetitive elements (rep‐PCR) random amplified polymorphic (RAPD‐PCR). These (PCR)‐based techniques simultaneously evaluated capacity detect genetic variation at...
To identify Stagonospora avenae genetically, 53 isolates from Europe and North America were assessed by RFLP analysis internal transcribed spacer (ITS) sequence polymorphisms in comparison with of S. nodorum, arenaria Septoria tritici. Our results also provided insight on possible phylogenetic divergence within the species currently identified characteristic conidial morphology as avenae. Isolates Europe, Canada, Minnesota Dakota showed little genetic variation. In ITS analyses, New York...
Full-length coding sequences of the beta-tubulin gene (tubA) were PCR-amplified and sequenced from 42 Phaeosphaeria isolates, including 16 P. nodorum 23 avenaria species cereals, two Polish isolates rye (Secale cereale L.), one isolate dallis grass (Paspalum dilatatum Poir). A tubA size 1556bp was identified in wheat- barley-biotype (PN-w PN-b), f. sp. (Paa), homothallic triticea (P.a.t.) (Pat1) P.a.t. (Pat3) State Washington. The length polymorphisms detected (Pat2) foxtail barley (Hordeum...
Abstract Spring and winter triticale wheat were used to study seed transmission the effect of seedborne inoculum on Stagonospora nodorum blotch in field. Infected was shown serve as a source primary epidemics disease cereals. Seedborne (Berk.) detected efficiently oxgall agar medium well yeast malt extract potato dextrose media. The infection with S. subsequent leaf glume severity field studied fungicides normally management programmes. Planting highly infested resulted more severe than did...
