Sources of Resistance to Selected Fungal, Bacterial, Viral and Nematode Diseases of Soybeans

摘要

Soybean breeders and plant pathologists often have difficulty finding sources of resistance to soybean pathogens because the relevant information is scattered in many publications with a limited circulation. This publication provides an organized reference of soybean diseases for professionals concerned with this problem. Of over 100 soybean pathogens known to exist, only 35 are of economic importance. This report considers 19 diseases, of which 11 are caused by fungi, 4 by viruses, and 2 each by nematodes and bacteria. A description of the pathogens, their symptoms, and photographs of infected plants are provided.
