Mutant Variety Database for Climate-Smart Crops Enhanced With New Tools and Features

By Cinthya Zorrilla

A global database of new crop varieties developed by mutation breeding has been upgraded and expanded to include data on mutant microbial bacteria and fungi strains as well as mutant plant varieties. The Mutant Variety Database (MVD) now offers enhanced tools to support breeders in developing climate-smart crops, strengthening global food security and sustainable agricultural practices.

For over 60 years, the IAEA, through the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture, has maintained and curated the MVD, which serves as the world’s primary repository for officially released mutant crop varieties. With over 3450 records across more than 70 plant species — including both seed and vegetatively propagated crops — it provides a unique resource for plant scientists around the world.

“The Mutant Variety Database is a specialized platform that brings together data, technology and knowledge exchange,” said Dongxin Feng, Director of the Joint FAO/IAEA Centre. “It enables breeders, researchers and policymakers to showcase the results of research and scientific knowledge translated into tangible technologies that are creating impact for small-scale farmers.”
