Book excerpt: Cereal cyst nematode (CCN) is acknowledged globally as a biotic constraint for wheat production, particularly under rain-fed conditions and drought stress. The first meeting of the International Cereal Cyst Nematode Initiative, held 21-23 October 2009 in Turkey, involved over 22 countries and 60 scientists from wheat-growing regions in Asia, Australia, Europe, North Africa and North America. It featured over 50 scientific presentations to provide valuable insight into the impact of CCN.

Book Synopsis Breeding for Root Lesion Nematode Resistance in Montana Winter Wheat by : David Bruce May (III.)
Download or read book Breeding for Root Lesion Nematode Resistance in Montana Winter Wheat written by David Bruce May (III.) and published by . This book was released on 2015 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root lesion nematodes (RLN; Pratylenchus spp.) present a serious challenge to dryland wheat production worldwide. Development of resistant cultivars would provide great economic benefit to growers. From 2012-2013, a set of backcross lines (MT08185//MT08184/Persia 20) was screened twice for resistance to P. neglectus. Progeny and parent lines were grown in infested soil for 16 to 18 weeks. Nematodes were then extracted from roots of individual plants and counted to obtain per plant final populations. ANOVA results from the 2013 screen showed significant differences in mean P. neglectus populations among lines (p
Book Synopsis Root-lesion Nematodes by : Richard W. Smiley
Download or read book Root-lesion Nematodes written by Richard W. Smiley and published by . This book was released on 2015 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. This publication provides a description and information on biology, symptoms, yield reduction, crop management, sampling, and identification related to root-lesion nematodes in Pacific Northwest wheat cropping systems.
Book Synopsis Identifying Root-lesion Nematode (Pratylenchus Spp.) Resistance and Functional Mechanisms in Wheat by : Alison Louise Thompson
Download or read book Identifying Root-lesion Nematode (Pratylenchus Spp.) Resistance and Functional Mechanisms in Wheat written by Alison Louise Thompson and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Root-lesion nematodes (RLN) Pratylenchus thornei Sher and Allen, 1953 and P. neglectus (Rensch, 1924) Filipjev Schuurmans and Stekhoven are soil-borne pathogens of wheat that invade and feed on root host cells. In the Pacific Northwest (PNW) these species of nematode were found in 95% of sampled fields and were estimated to cause 37% - 50% yield loss in spring wheat. Resistance to P. thornei had previously been found in 78 Iranian landrace accessions. The accessions were tested for resistance to P. neglectus and 21 accessions were found to be resistant to both species. The dual-resistant landrace accession, AUS28451 (PI623470), was used to generate a recombinant inbred line (RIL) population by crossing it to the susceptible PNW cultivar, Louise. One-hundred and fifty F2:F6 derived RILs were genotyped using SSR and SNP based molecular markers. The RILs were then phenotyped using inoculated field soil greenhouse assays where nematodes counted at the end of a 12 week period. A new root rating method to determine nematode resistance was also developed and tested in the greenhouse assays. Resistance associated quantitative trait loci (QTL) were identified on chromosomes 1A, 2B, 4A, 5A, 5B, 6B and 7A using both phenotyping methods for P. thornei and P. neglectus. Canopy temperature and photosynthesis yield (phiPSII) were used to develop a prediction model for nematode population densities on resistant and susceptible cultivars planted in infested fields. The RIL population was used to verify the accuracy of the prediction model. Predicted nematode resistance associated QTL were identified on chromosomes 4A, 5A, 6A, 6B, and 6D. Root morphology observations suggested AUS28451 (PI623470) had increased root lignin content compared to Louise. Root lignin content was examined in the RIL population and associated QTL were identified on chromosomes 2D and 5B. With this research, three new methods for indirect Pratylenchus resistance screening have been developed. These methods include molecular markers associated with resistance, root ratings, and field stress measurements. With these methods breeders will be able to incorporate nematode resistance breeding into their programs using a variety of tools.

Book Synopsis Genetic and Biological Characterisation of Resistance to Root Lesion Nematode Pratylenchus Thornei in Wheat by : Katherine Joanne Linsell
Download or read book Genetic and Biological Characterisation of Resistance to Root Lesion Nematode Pratylenchus Thornei in Wheat written by Katherine Joanne Linsell and published by . This book was released on 2013 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root lesion nematodes of the genus Pratylenchus feed and reproduce in the root cortex of many plant species, including wheat. Migration through root tissue causes extensive root damage, and in turn severe reductions in growth and yield. In Australia, one of the most prevalent and widespread species affecting wheat is Pratylenchus thornei. Due to the wide host range of Pratylenchus spp. and the restrictions and inefficiency of chemical pesticides, the development of resistant cultivars has become increasingly important. Despite the identification and investigation of several resistance sources and resistance quantitative trait loci (QTL), no P. thornei resistance has been integrated into commercial cultivars. In addition, prior to this study, the biological resistance mechanisms of wheat against P. thornei were not well characterised. The identification of novel sources of genetic resistance in wheat and understanding of the biological mechanisms will allow effective combinations of genes either to be used alternatively or pyramided to generate effective and stable Pratylenchus resistance. The major objectives of the study were to identify genetic loci associated with P. thornei resistance and to investigate the associated biological mechanisms in a double haploid wheat population developed from a cross between the synthetically derived Sokoll and the Australian adapted Krichauff parental lines.

Book Synopsis Rainfed Farming Systems by : Philip Tow
Download or read book Rainfed Farming Systems written by Philip Tow and published by Springer Science & Business Media. This book was released on 2011-09-16 with total page 1324 pages. Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.
