Interpretive Summary: The characterization of soybean hereditary material has resulted in a 'road map' of it's DNA. Many important characteristics of the soybean are attributed to genes on this map. These include genes for nutritional components and disease resistance. The position of well over lOO genes has been identified. The authors have summarized information from approximately 90 scientific publications and compiled the data into this review book chapter. Knowing where genes are on a genetic road map will help breeders manipulate them in breeding programs. Faster and more efficient breeding programs will provide the public with new and improved plant products faster and cheaper.
Technical Abstract: Soybean genetic maps have been integrated using RFLP, RAPD and SSR markers. The map is now comprised of the predicted 20 linkage groups covering approximately 2550 cM and containing nearly 600 markers. More than 60 classical qualitative traits have been placed onto this map QTL for nearly 30 quantitative traits have been identified as well. In addition, QTL for 10 disease resistance traits expressed quantitatively have also been identified and mapped. Approximately 90 critical references are assessed for reliable information concerning soybean genomics.
