The Molecular Maize Atlas encourages genetic diversity

CIMMYT’s germplasm bank contains about 28,000 unique samples of cultivated maize and its wild relatives, teosinte and Tripsacum. These include about 26,000 samples of farmer landraces — traditional, locally-adapted varieties that are rich in diversity. The bank both conserves this diversity and makes it available as a resource for breeding. (Photo: Xochiquetzal Fonseca/CIMMYT)

With so much germplasm to categorize, what’s the best way to label them? Seeds of Discovery is working on the answer.

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.

Study reveals diversity “blueprint” to help maize crops adapt to changing climates

By Julie Mollins

Scientists have unlocked evolutionary secrets of landraces through an unprecedented study of allelic diversity, revealing more about the genetic basis of flowering time and how maize adapts to variable environments, according to new research published in Nature Genetics journal. The discovery opens up opportunities to explore and use landrace diversity in new ways to help breeders adapt crops to climate change and other emerging challenges to crop production.
