Guidelines for the quality control of Quality Protein Maize (QPM) seed and grain

This guidebook is the first of its kind to provide recommendations and a framework for monitoring quality assurance of QPM. Guidelines are based on QPM genetics, breeding, characteristics, and nutritional benefits. It lists the QPM varieties based on CIMMYT germplasm that have been released worldwide. Furthermore, it elucidates the concepts of seed quality control, seed production and certification systems, definition of protein quality in QPM, methods for laboratory analysis of protein quality in QPM, sampling procedures for submitting samples to the lab, and sourcing a laboratory for analysis; it also gives recommendations for quality control in both QPM grain and recycled seed. This technical bulletin is intended to serve mainly as background information based on which to develop national QPM seed and grain quality control and assurance standards in countries where QPM is produced and marketed.
