The future direction of oilseeds appears to be closely tied to patents around seed technology, as industry and governments plan for a net-zero future. CIMMYT’s germplasm bank is available worldwide and relies heavily on collaborations with public and private entities, where breeding is a critical part of partnerships to further foster thriving markets.

“We’ll never get back all the diversity we had before, but the diversity we need is out there,” says Matthew Reynolds, head of wheat physiology at CIMMYT.
As climate breakdown and worldwide conflict continue to place the food system at risk, seed banks from the Arctic to Lebanon try to safeguard biodiversity.
Seed banks may be another resource for securing Indigenous seed, although these banks have other missions as well. The International Maize and Wheat Improvement Center (CIMMYT), maintains seed banks and programs to preserve seeds native to specific regions. The group also leads the CGIAR Research Programs on Maize and Wheat and the Excellence in Breeding Platform to characterize genetic diversity so it can be used in conventional breeding programs to develop wheat and maize varieties that can address climate change, pest and disease resistance and yield to help manage food security.
“About 100 seed banks exist worldwide with seed used for cultural or heritage purposes and for production. CIMMYT has varieties that have been cultivated, conserved and cherished as grain and food crops for thousands of years,” says Tom Payne, head of the non-profit organization’s wheat germplasm collections and International Wheat Improvement Network. “Our seed bank conserves varieties that can be a source for finding old genes that will solve new problems. We have to have that diversity to address changing production environments.”

Maize is more than a crop in Mexico. In many cases, it connects families with their past. Landraces are maize varieties that have been cultivated and subjected to selection by farmers for generations, retaining a distinct identity and lacking formal crop improvement. They provide the basis of Mexico’s maize diversity.
Back in 1966-67, researcher Ángel Kato from the International Maize and Wheat Improvement Center (CIMMYT) collected 93 maize landraces samples from 66 families in Mexico’s state of Morelos. These seeds were safeguarded in CIMMYT’s Germplasm Bank, which today stores 28,000 samples of maize and its wild relatives from 88 countries.
50 years later, doctoral candidate Denisse McLean-Rodriguez, from the Sant’Anna School of Advanced Studies in Italy, and researchers from CIMMYT started a new study to trace the conservation and abandonment of maize landraces over the years.
The study shows that landrace abandonment is common when farming passes from one generation to the next. Older farmers were attached to their landraces and continued cultivating them, even in the face of pressing reasons to change or replace them. When the younger generations take over farm management, these landraces are often abandoned. Nonetheless, young farmers still value the cultural importance of landraces.
Maize landraces can be conserved “in situ” in farmers’ fields and “ex situ” in a protected space such as a germplasm bank or community seed bank. The loss of landraces in farmers’ fields over 50 years emphasizes the importance of ex situ conservation. Traits found in landraces can be incorporated into new varieties to address some of the world’s most pressing agriculture challenges like changing climates, emerging pests and disease, and malnutrition.
This research was supported by the CGIAR Research Program on Maize (MAIZE), the Sant’Anna School of Advanced Studies, Wageningen University and the Global Crop Diversity Trust.
The CIMMYT germplasm bank is located near Texcoco, Mexico and is known for Norman Borlaug, father of modern agriculture and the “Green Revolution” who fought hunger in the later 1940s.

Imagine walking through a grocery store, doing your weekly shopping. Everything seems normal, but as you pick up a can, there’s no label. There’s nothing to tell you what the product is, and now you can’t reliably choose anything to eat this week.
Now switch gears and imagine a germplasm bank. Without the right labeling on these different varieties, it’s difficult to tell what’s new and what’s already been discovered when working on new research projects.
That’s where the Molecular Maize Atlas steps into play.
About nine years ago, the International Maize and Wheat Improvement Center (CIMMYT) started an initiative called the Seeds of Discovery (SeeD). This initiative facilitates easier access to and use of maize and wheat genetic resources.
SeeD achieves impact through five main components: genotyping, phenotyping, software tools, pre-breeding and capacity building.
“One of the aims of Seeds of Discovery was to best characterize germplasm,” says Sarah Hearne, a molecular geneticist and maize lead of SeeD. “At CIMMYT, our international germplasm bank holds in trust one of the largest and most diverse publicly available maize collections in the world.”
However, Hearne says this germplasm bank used to look like a grocery store without any labels or without labels that would allow someone to select a can of value. To combat this, SeeD decided to work on a labeling process for the germplasm bank: the Molecular Maize Atlas.
The Molecular Maize Atlas is an information platform that brings genotypic data resources and associated tools together. This genotypic data provides unifying information across landraces and acts as a common backbone, which other valuable information, like phenotypic data, can be added to.

On 19 November, CIMMYT hosted well-known food historian Rachel Laudan, who is currently conducting maize research and came to CIMMYT to interact with maize scientists to better understand the current state of maize in Mexico. Laudan’s website with links to her books, blog, and more may be found here. Read her recent article ‘A Plea for Culinary Modernism’ in Jacobin magazine here.
