New genetic mapping study offers hope of resistance to maize lethal necrosis

A new study from scientists with the International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR Research Program on Maize (MAIZE) in Kenya has revealed key information about the genetic basis of maize lethal necrosis (MLN), a disease that has been wreaking havoc on maize crops in eastern Africa since its discovery in the region in 2011.

Maize is the main staple food crop in sub-Saharan Africa and is cultivated on more than 35 million hectares of rain-fed agricultural land, providing sustenance to millions. The MLN disease, caused by a combination of the maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV), causes irreversible damage that kills maize plants before they can grow and produce grain. Yield losses from infected fields in Kenya range from 30-100 percent, depending on the stage of disease infection and the prevailing environmental conditions. Such losses dramatically increase the risk of food insecurity in the region and weaken the ability of smallholder farmers to feed their families.

Screening cycle for deadly MLN virus set to begin in Kenya during April 2018

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin its phenotyping (screening/ indexing) cycle of 2018 at the begining of January, 2018 and in other four intervals, interested organizations from both the private and public sectors are invited to send maize germplasm for screening.

In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.

Successfully combatting aflatoxin in Kenya’s food with Aflasafe on a large scale

Flashback: In early 2015, Kenya’s National Irrigation Board (NIB) purchased Aflasafe to help deal with aflatoxin contamination in maize, a predicament afflicting some of its irrigation schemes. For example, in most years, the UN’s World Food Programme was unable to purchase maize from the towns of Hola and Bura in Kenya owing to excessive aflatoxin. Fastforward to 2017: What were the results of this NIB purchase then, and today, two years on? Read on!

It’s blowing in the wind. Follow Sarah Chughu’s ‘pointing’ finger. See the tiny specks in the clouds on the left? That’s Aflasafe KE01 which Sarah was broadcasting at Galana-Kulalu, Eastern Kenya, in July 2016. An all-natural product, Aflasafe consistently reduces aflatoxin by between 80 and 99% at harvest and in storage. (Photo: U Mutuku/IITA)
