Strategic Initiative 8: Seeds of discovery<br />

Genesis and justification<br />

Accelerated developments in genomics, bioinformatics and phenotyping enable scientists, for the first<br />

time in history, to begin to unlock the black box of native genetic diversity of major crops. Holding in<br />

trust the most important germplasm bank for tropical maize, MAIZE tackles this challenge in<br />

collaboration with the most advanced public and private sector institutes.<br />

Outcomes<br />

Enable researchers to mobilize the full potential of maize biodiversity in breeding programs worldwide.<br />

This will help speed breeding gains and enable the world community to counteract the accumulating<br />

effects of climate change and scarcities of water, land and nutrients.<br />

Methods<br />

Apply next generation sequencing technologies and state‐of‐the‐art precision phenotyping to the<br />

most relevant cross‐section of native maize genetic diversity.<br />

Develop Web‐based user‐friendly platforms.<br />

Promote the flow of useful diversity into research and breeding programs worldwide via access to<br />

seeds of well‐characterized accessions.<br />

Capture into elite backgrounds both large‐effect QTL alleles via marker‐assisted introgression and<br />

small‐effect alleles via rapid‐cycle genomic selection.<br />

Outstanding innovations<br />

First attempt to comprehensively characterize the global heritage of maize genetic resources to<br />

promote flow of useful diversity into research and breeding programs.<br />

A world‐first breeder‐ and researcher‐friendly “catalog” for the CIMMYT‐ and IITA‐held maize seed<br />

“libraries”, transforming them from black box germplasm banks to accessible trait, gene and marker<br />

libraries.<br />

Strategic Initiative 9: New tools and methods for NARSs and SMEs<br />

Genesis and justification<br />

New breeding tools, notably high‐density genotyping, doubled haploids and improved informatics, are<br />

rapidly increasing rates of genetic gain in the breeding programs of multinational seed companies.<br />

Responding to the demand from NARSs and local seed companies, this Initiative will provide them with<br />

access to these tools to accelerate breeding progress targeted at poorer farmers. Collaborations with<br />

the multinationals and ARIs have already been developed to enable this Initiative, with CIMMYT and IITA<br />

acting as “honest brokers” that respect intellectual property and trade secrets while developing and<br />

making prioritized non‐proprietary know‐how and tools widely available. This Initiative aligns and often<br />

pioneers approaches that are then scaled up by the Genomics and Integrated Breeding Service (GIBS),<br />

for use by other cross‐pollinated and hybrid crops with lesser importance and hence lesser investment.<br />
