The CIMMYT maize germplasm bank is the lifeblood of many MAIZE activities, preserving the genetic diversity that is necessary to develop improved maize varieties farmers need to feed a growing population in a changing climate.
The bank contains over 28,000 unique collections of seed of maize and related species from 88 countries. These collections represent the genetic diversity of unique native varieties and wild relatives of maize and are held under long-term storage for the benefit of humanity in accordance with the 2007 International Treaty on Plant Genetic Resources for Food and Agriculture. The collections are also studied and used as a source of diversity to breed for crucial traits such as heat and drought tolerance, resistance to crop diseases and pests, grain yield productivity and grain quality. Seed is freely shared on request to researchers, students, and academic and development institutions worldwide.

Breeding and seed systems must be adapted to survive projected climate change if major loss of maize yields is to be avoided, a new report shows.
Tools that forecast the response of crops to different weather and climate conditions, coupled with crop yield modeling have enabled agricultural scientists to predict and formulate plans for potential future climate change.

Only 20 years ago, the idea that maize could reduce vitamin A deficiency (VAD) would have been summarily dismissed. Agricultural scientists were focused on increasing yields and developing more robust varieties that could withstand the constant assault of new pests and diseases. The idea of making maize and other staple food crops more nutritious by breeding in vitamins and minerals, a process called biofortification, was a novel concept. However, with the launch of HarvestPlus in 2003, a collaborative research partnership was launched to bring together scientists across disciplines in an effort to reduce hidden hunger caused by micronutrient deficiencies. One of the fruits of this partnership were the world’s first “orange” maize varieties rich in vitamin A. This ‘orange’ vitamin A maize has been conventionally bred to provide higher levels of provitamin A carotenoids, a naturally occurring plant pigment also found in many orange foods such as mangoes, carrots and pumpkins, that the body then converts into vitamin A.
In South Asia, 90 percent of smallholder farmers using fertilizer do not achieve optimum crop yields due to a lack of access to soil testing services. In response to this information gap, the International Plant Nutrition Institute (IPNI) South Asia Program developed the Nutrient Expert® decision support tools in partnership with MAIZE CRP to provide location-specific fertilizer recommendations for farmers growing maize and wheat.
In February 2014, the tool received the award for Best Innovation at the Bihar Innovation Forum II, which recognizes innovations to improve rural livelihoods in India. Nutrient Expert® is the product of close collaboration with key partners such as national agricultural research and extension systems (NARES), seed and fertilizer industries, non-governmental organizations, farmers’ and women’s self-help clubs in India.
