This publication is a compilation of reports on all plant species and varieties that have been called either resistant or tolerant to infestation by the root knot nematode, Heterodera marioni (Cornu) Goodey, (formerly called H. radicola (Greef) Mueller). The purpose is twofold: to bring together all available information on the subject in condensed form for the use of growers, plant breeders, and other investigators, and to establish a basis for the contribution of further data. It must not be assumed that all of the plants listed here are recommended as resistant. They intention is rather to present technical source material, not only useful to those who need practical information on particular plants but also suggestive to future workers.

This is a reproduction of the original artefact. Generally these books are created from careful scans of the original. This allows us to preserve the book accurately and present it in the way the author intended. Since the original versions are generally quite old, there may occasionally be certain imperfections within these reproductions. We're happy to make these classics available again for future generations to enjoy!

Experience shows that biotic stresses occur with different levels of intensity in nearly all agricultural areas around the world. The occurrence of insects, weeds and diseases caused by fungi, bacteria or viruses may not be relevant in a specific year but they usually harm yield in most years. Global warming has shifted the paradigm of biotic stresses in most growing areas, especially in the tropical countries, sparking intense discussions in scientific forums. This book was written with the idea of collecting in a single publication the most recent advances and discoveries concerning breeding for biotic stresses, covering all major classes of biotic challenges to agriculture and food production. Accordingly, it presents the state-of-the-art in plant stresses caused by all microorganisms, weeds and insects and how to breed for them. Complementing Plant Breeding for Abiotic Stress Tolerance, this book was written for scientists and students interested in learning how to breed for biotic stress scenarios, allowing them to develop a greater understanding of the basic mechanisms of resistance to biotic stresses and develop resistant cultivars.
