Novel genetic diversity for these programs is readily available from CIMMYT’s germplasm bank, which hosts the largest collection of maize and wheat in the world: 28,000 accessions of maize and over 120,000 accessions of wheat landraces and wild relatives. I discuss how approaches to discovery and deployment of useful diversity from this collection have evolved over time, from ad hoc breeding efforts to systematic genetic screening, and from exploitation of major gene variants to use of quantitative variation. Specifically, I examine how quantitative genetic approaches have become increasingly important in both discovery and deployment and how we are currently using such approaches in ongoing ‘allele mining’ efforts.
