The document describes the Breeding Management System (BMS), a comprehensive suite of informatics tools developed by the International Breeding Platform (IBP) to support plant breeding programs. The BMS includes nine key components to manage breeding activities from project planning to selection decision-making. It is intended to help public breeding programs in developing countries implement integrated informatics and make better use of molecular breeding technologies. The BMS has flexible and customizable features, and provides access to genotyping services and analysis tools supported by the IBP and CGIAR.
