Book excerpt: Excerpt from Relative Susceptibility of Spring-Wheat Varieties to Stem Rust Black stem rust probably causes greater losses to the spring-wheat crop than all other diseases combined. Nearly all of the hard red spring-wheat varieties now grown are very susceptible to rust. Some varieties of durum wheat are much more susceptible than others. Uniform spring-wheat nurseries were sown at 39 experiment sta tions in the United States and Canada during one or more of the six years from 1919 to 1924, inclusive. The percentages of infection of stem rust of the 33 varieties of wheat which were grown in all or some of the uniform nurseries are reported in this circular. Percent age estimates oi rust infection were recorded in 107 of the 113 station years during which the nurseries were grown. Heavy rust infection occurred at most stations each year. The durum wheats were much more resistant as a class than the hard red spring wheats. Pentad, Monad, Acme, and N odak are the most resistant. Kota and a few new hybrid wheats are much more resistant to rust than Marquis. Marquis escapes rust slightly better than Power, Preston, and Haynes Bluestem. Except for the resistant varieties, the average rust infection on the common wheats increased with the lateness of the average date of maturity of the varieties. Early varieties evade rust better than Marquis. The two varieties of spring emmer were nearly immune to rust. The reduction of losses from stem rust of wheat by growing resist ant varieties is a certain and feasible method. The varieties to grow depend upon local adaptation and market value as well as rust resistance. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Wheat Blast provides systematic and practical information on wheat blast pathology, summarises research progress and discusses future perspectives based on current understanding of the existing issues. The book explores advance technologies that may help in deciding the path for future research and development for better strategies and techniques to manage the wheat blast disease. It equips readers with basic and applied understanding on the identification of disease, its distribution and chances of further spread in new areas, its potential to cause yield losses to wheat, the conditions that favour disease development, disease prediction modelling, resistance breeding methods and management strategies against wheat blast. Features: Provides comprehensive information on wheat blast pathogen and its management under a single umbrella Covers disease identification and diagnostics which will be helpful to check introduction in new areas Discusses methods and protocol to study the different aspects of the disease such as diagnostics, variability, resistance screening, epiphytotic creation etc. Gives deep insight on the past, present and future outlook of wheat blast research progress This book’s chapters are contributed by experts and pioneers in their respective fields and it provides comprehensive insight with updated findings on wheat blast research. It serves as a valuable reference for researchers, policy makers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat.

Download or read book Durability of Disease Resistance written by Th. Jacobs and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.

Book excerpt: Although stem rust has been controlled by means of resistant cultivars, leaf and stripe rust continue as problems for many growing areas of the world. Wheat Rusts: An Atlas of Resistance Genes has been prepared by specialists from one of the leading international laboratories, and illustrates with colour photographs typical resistance phenotypes associated with most known genes for resistance to the three rust diseases of wheat. Relevant details for each gene include chromosome location, aspects of genetics and pathogen variation, the effects of environment on expression, origin, availability in genetic and breeding stocks, and use in agriculture. This atlas includes an introduction to host:pathogen genetics, methodologies for wheat rust research and breeding for resistance.

Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.
