This book was released on 2003 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive record of current knowledge on the nature of Fusarium head blight, the damage it causes, and current research on how to control it. The book begins with a historical account of Fusarium head blight epidemics that gives context to recent attempts to control epidemics in wheat and barley. A review of pathogen taxonomy and population biology helps scientists to see relationships among head blight pathogens and other Fusarium species. The information on epidemiology included in this review also provides an understanding of the weather conditions and cultural practices that promote explosive epidemics. New information on infection processes will lead the reader to a better understanding of how to breed for resistance in wheat and barley.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium head blight (FHB) caused by Fusarium graminearum is an important consideration in cereal production as the fungus reduces yields and deposits mycotoxins in grain. Characteristics of the Fusarium spp. population found in the Maritime provinces of Canada are not well understood thus, an objective of this study was to describe the local population. Wheat and barley samples from 39 sites across the Maritimes were surveyed to determine Fusarium spp. and mycotoxins present from 2018 to 2021. Management of FHB may be supported by disease forecasting systems therefore, FHB forecasts were evaluated in comparison to epidemic records and field experiments. Fusarium graminearum was the primary causal species of concern and deoxynivalenol was the most abundant mycotoxin detected each year. FHB was most accurately forecasted using 7-day pre-anthesis relative humidity and temperature. This study represents the first multi-year survey of FHB causal species and evaluation of FHB forecasting in the Maritimes.

Download or read book Fusarium Head Blight in Canadian Winter Wheat written by Harwinder Sidhu and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium Head Blight (FHB) is a devastating disease of Wheat (Triticum aestivum L.) caused primarily by Fusarium graminearum Schwabe in Canada. Wheat FHB results in yield and produce quality losses. The clearest symptoms of FHB are premature bleaching of spikelets in the field, and fusarium damaged kernels in the harvested seed. Insufficient and costly disease control strategies make breeding for FHB resistance in wheat an ideal choice. There is a lack of FHB resistance sources in the Canadian wheat germplasm and Genome Wide Association Studies (GWAS) can be utilized to identify such sources. Furthermore, as no Quantitative Trait Loci (QTL) provides absolute resistance to FHB, identification of novel sources of resistance is desired. Genomic Selection (GS) has great potential in crop improvement, specifically for quantitative traits. A diversity panel that represents the genetic diversity of the Canadian, i.e., high latitude North American winter wheat was assembled for this thesis and the genetic diversity, population structure, and linkage disequilibrium of the germplasm was studied. To identify QTL associated with FHB, a GWAS study was conducted using the phenotypic data collected at three locations over two years. For understanding the role of number of genotypic markers, population structure, and choice of model in trait prediction modelling, a GS study was conducted. The Canadian Winter Wheat Diversity Panel is a diverse collection of winter wheat capturing diversity both in time and geography from Canada. The panel comprises of seven subpopulations with different LD, allele frequencies, and genetic diversity parameters. Multiple QTL associated with FHB related traits were identified on 13 chromosomes which may harbor genes involved in plant defense and stress response mechanisms. For FHB resistance improvement, the GS study demonstrated that the modelling parameters can be determined based upon the genotypic information available. Deoxynivalenol contamination was one of the traits with the highest prediction accuracy. GS can account for minor effect QTL, which is beneficial when breeding for quantitative traits. FHB resistant varieties are needed for an effective and economical disease control strategy in wheat and GS can complement current breeding efforts to develop FHB resistant wheat varieties.

Download or read book Species Diversity of Fusarium Head Blight and Deoxynivalenol DON Levels in Western Canadian Wheat Fields and Generating Leptosphaeria Maculans Isolates Carrying Single Avirulent Avr Genes written by Sachithrani Kannangara and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat and canola are two major economically important food crops grown in western Canada, accounting for billions of dollars in revenue. Fusarium head blight (FHB) in wheat and blackleg in canola are the most destructive diseases that cause economic losses annually. Both diseases are caused by fungal pathogens, where FHB is primarily caused by Fusarium graminearum, while Leptosphaeria maculans causes the blackleg disease. This project's first objective is to evaluate the Fusarium species diversity and deoxynivalenol (DON) levels in western Canadian wheat fields in 2019 and 2020. The analysis of deoxynivalenol (DON) revealed that spring wheat grain contained higher DON levels than winter wheat grain samples. Additionally, for spring wheat, a significantly lower DON content was found in the grain than in the chaff collected from the same wheat heads for both years. The species diversity analysis showed that F. graminearum was the most frequent Fusarium species found in the infected samples except the samples from Alberta, while the highest percentage of F. graminearum was found in the spring wheat samples from Manitoba. The analysis of chemotype diversity of infected samples showed that 3ADON is the dominant chemotype in FHB disease. For the blackleg disease, a growing concern among blackleg researchers is that resistance (R) genes are identified, the same gene as two different genes by two independent laboratories, as not all research laboratories use a standard set of well-characterized isolates. To standardize the R gene identification and novel R gene discovery, the second objective of this thesis is to develop a procedure to generate L. maculans isolates that only carry a single avirulent (Avr) gene. Mating between two L. maculans isolates showed less efficiency in achieving the above objective. Thus, gene editing with the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 was utilized. Seven transformed isolates displayed reduced virulence on the canola cultivar Westar, even though they were not mutated at the target gene.
