The Maize Lethal Necrosis (MLN) Screening Facility quarantine site in Naivasha, Kenya, is used to provide MLN phenotyping services at cost to national agricultural research systems and seed companies in Africa.

The International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture and Livestock Research Organization (KALRO) have been screening germplasm against MLN in Kenya since November 2012. The dedicated screening facility in Naivasha was established in 2013. This facility now represents a high-quality phenotyping platform, permitting large-scale screening of germplasm from regional public and private partners.

The facility has enabled CIMMYT and its partners to identify numerous materials that are resistant or tolerant to this devastating maize disease. Many of these products are featured in CIMMYT’s Maize Product Catalog.
