Based on the 2014 'Enhanced Genepool Utilization ? Capturing wild relative and landrace diversity for crop improvement' conference , in this book a team of international contributors address all aspects of utilization and conservation of crop wild relative (CWR) and landrace (LR) diversity for crop improvement. Focussing on characterisation techniques, conservation strategies, facilitating CWR and LR use and informatics development, this book highlights exotic plant germplasm as a potentially critical but neglected resource for crop improvement.
