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.

Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Download or read book The Fusarium Laboratory Manual written by John F. Leslie and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time in over 20 years, a comprehensive collection of photographs and descriptions of species in the fungal genus Fusarium is available. This laboratory manual provides an overview of the biology of Fusarium and the techniques involved in the isolation, identification and characterization of individual species and the populations in which they occur. It is the first time that genetic, morphological and molecular approaches have been incorporated into a volume devoted to Fusarium identification. The authors include descriptions of species, both new and old, and provide protocols for genetic, morphological and molecular identification techniques. The Fusarium Laboratory Manual also includes some of the evolutionary biology and population genetics thinking that has begun to inform the understanding of agriculturally important fungal pathogens. In addition to practical “how-to” protocols it also provides guidance in formulating questions and obtaining answers about this very important group of fungi. The need for as many different techniques as possible to be used in the identification and characterization process has never been greater. These approaches have applications to fungi other than those in the genus Fusarium. This volume presents an introduction to the genus Fusarium, the toxins these fungi produce and the diseases they can cause. "The Fusarium Laboratory Manual is a milestone in the study of the genus Fusarium and will help bridge the gap between morphological and phylogenetic taxonomy. It will be used by everybody dealing with Fusarium in the Third Millenium." --W.F.O. Marasas, Medical Research Council, South Africa

Download or read book Effects of Fungicide Chemistry and Application Timing on Fusarium Head Blight and Deoxynivalenol in Soft Red Winter Wheat written by Daisy L. D'Angelo and published by . This book was released on 2013 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Demethylation Inhibitors (DMI) and Quinone Outside Inhibitors fungicides are important components of wheat disease management programs. However, only members of former group are usually recommended for the control of Fusarium head blight (FHB) and deoxynivalenol (DON). Since wet, humid conditions during anthesis and early grain fill are highly conducive to FHB development, DMI fungicides are commonly recommended for FHB management when anthesis coincides with wet weather. However, there are several practical limitations to applying a fungicide at anthesis. Research is needed to determine whether applications made after anthesis will provide adequate control of this disease and its associated toxins in soft red winter wheat under field conditions in the U.S. Midwest. In the case of the QoI, these are not usually recommended to FHB and DON management because some members of this group have been reported to increase instead of decrease DON in harvested grain. However, it is unclear whether all QoIs affect DON in the same manner and whether DON response to QoIs vary with application timing. The objectives of this study were to: 1) determine the effect of post-anthesis applications of 19% tebuconazole + 19% prothioconazole and 8.6% metconazole on FHB and DON in soft red winter wheat (SRWW) under different naturally infected and artificially inoculated field conditions, 2) determine whether the magnitude of FHB and DON responses to post-anthesis fungicide applications varied with active ingredient, cultivar, and baseline disease and toxin levels, and 3) estimate the efficacy (based on mean percent control of FHB index and DON) of post-anthesis treatments relative to untreated and anthesis reference treatments.; 4) determine the effects of two QoI active ingredients (22.9% azoxystrobin and 23.6% pyraclostrobin), relative to untreated checks and DMI (19% tebuconazole + 19% prothioconazole) reference treatments, on DON contamination of wheat grain and spikes; 5) determine whether the effect of QoIs on FHB index and DON was influenced by application timing; and 6) determine whether the relationships among index, DON, and Fusarium damaged kernels varied with active ingredient and application timing.

Download or read book Analysis of Resistance to Fusarium Head Blight FHB in Winter Wheat and Evaluation of Genetics and Cultural Practices for FHB Mitigation written by Zesong Ye and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium head blight (FHB) caused by Fusarium graminearum is a fungal disease of wheat that can result in severe yield losses and contaminate grain with deoxynivalenol (DON). Wheat cultivars with different levels of FHB resistance were combined with fungicides application to control FHB. Results showed that foliar fungicide ProsaroTM combined with moderately resistant cultivars greatly reduced the risk of FHB. Integrating fungicide application with moderately resistant cultivars can be an effective strategy in controlling FHB. Quantitative trait loci (QTL) for resistance to FHB related traits were analyzed using a double haploid population. Four QTL associated with FHB resistance was detected on chromosomes 2B, 2D, 4D and 7A. The QTL on chromosome 2B and 4D were found to reduce multiple FHB-related traits and were more frequently detected than QTL on chromosome 2D and 7A. QTL on chromosome 2B and 4D could be valuable for improving FHB resistance in wheat.
