Download or read book Wheat Rusts written by R. A. McIntosh and published by CSIRO Publishing. This book was released on 1995 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although stem rust is mostly controlled by means of resistance cultivars, leaf and stripe rust continue as major problems in many wheat-growing areas of the world. Wheat Rusts: An Atlas of Resistance Genes provides a basis to identify genes for resistance to stem, leaf and stripe rusts of wheat. Typical phenotypes associated with most known genes for resistance to these three diseases are illustrated in full colour. This book will assist plant breeders and pathologists to identify candidate resistance genes, thereby saving substantial time and resources. Prepared by well-known specialists from a leading international laboratory, Wheat Rusts: An Atlas of Resistance Genes comprises an introductory chapter, details of individual resistance genes, appendices and an index. Details for each gene include chromosome location, aspects of genetics and pathogen variation, the effect of environment of expression, origin, availability in genetic and breeding stocks and use in agriculture.

Book Synopsis Characterization of Virulence and Heat Stress Tolerance of Stripe Rust Populations in Kansas by : Heather Gardner

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stripe rust, caused by Puccinia striiformis f.sp. tritici has caused more yield loss than any other disease in the Great Plains wheat growing region since the year 2001. Despite efforts to control the disease with genetic resistance, epidemics have increased in severity over the last decade because of changes in the regional pathogen population. There is also evidence that some members of the population are more tolerant of heat stress than historical populations of the fungus. The objectives of this research are to document virulence variation within the population of the stripe rust pathogen with attention to adult plant resistance, quantify the influence of heat stress on the pathogen, and develop models that evaluate the role of heat stress in suppressing stripe rust epidemics in Kansas. Virulence changes of the pathogen were documented with collections of Puccinia striiformis f.sp. tritici isolates from 2010 to 2021 by determining infection type and disease severity on a set of differential wheat varieties that are commonly grown in Kansas. The results indicated a trend for increasing virulence against multiple sources of genetic resistance over this time period with a few varieties displaying consistent nonrace-specific adult plant resistance. Experiments in controlled environments indicated that temperatures above 20°C increased latent period, slowed the colonization of leaf tissue, and reduced sporulation intensity of the pathogen. Isolates varied in their response to heat stress with isolates collected since 2015 often resuming sporulation sooner than those collected a decade ago. Analysis of weather conditions associated with stripe rust epidemics during the past two decades confirmed the potential of heat stress events to suppress the development of regional stripe rust epidemics and lower the risk of disease-related yield losses. The modeling results provide guidance on specific temperature conditions and time periods when heat stress is most likely to suppress stripe rust development. The overall results of this project should help guide the development of wheat varieties with durable genetic resistance to stripe rust and help wheat disease specialists evaluate the likelihood that heat stress events will slow the development of regional stripe rust epidemics.

Available in PDF, EPUB and Kindle. Book excerpt: Wheat (Triticum spp.) stem rust, caused by Puccinia graminis f. sp. tritici Eriks. & E. Henn. (Pgt), re-emerged as a devastating disease of wheat because of virulent race Ug99 (TTKSK). Many modern bread wheat ( T. aestivum L.) cultivars grown in North America are susceptible to Ug99 or its derivative races with additional virulence. 'Gage', a USDA-University of Nebraska developed hard red winter wheat cultivar, was released in 1963 mainly for its excellent field resistance to leaf rust caused by Puccinia triticina Eriks and stem rust which was superior to another stem rust resistance cultivar, 'Scout66'. However, Gage's resistance has not been genetically characterized to facilitate its use in breeding programs. For molecular marker and genetic analysis, we created an F2 population and the corresponding F2:3 and F4:5 families from crosses between Gage and stem rust susceptible cultivar 'Bill Brown'. Inheritance of seedling resistance to Pgt race QFCSC and molecular marker analysis indicated that genes in addition to Sr2 explain the stem rust resistance of Gage. Using seedling plant infection types from the F2, F2:3 and F4:5 families, we confirmed that at least one dominant and most likely one recessive gene are involved in Gage's resistance. Seedling resistance genes acted independently of Sr2 since Sr2 is effective only at the adult plant stage. The relationship between adult plant resistance (APR) molecular marker gwm533 for Sr2 and adult plant disease response in the greenhouse indicated that Sr2 and at least one unknown resistance gene are involved in APR as plants without gwm533 indicative of Sr2 appeared resistant. We characterized the stem rust resistance in Gage and identified potential molecular markers linked to seedling resistance.
