Maize Lethal Necrosis Phenotyping Service

The CIMMYT-Kenya Agriculture and Livestock Research Organization (KALRO) Maize Lethal Necrosis (MLN) Screening Facility quarantine site is used to provide an MLN Phenotyping Service at cost to national agricultural research systems and seed companies in Africa.

KALRO and CIMMYT have been screening germplasm against MLN in Kenya since Nov 2012. The dedicated screening facility at KALRO 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.

To date, close to 90 percent of materials screened at Naivasha are susceptible under artificial inoculation. However, resistant and tolerant materials have been identified. Four first-generation MLN tolerant and resistant hybrids have been released in East Africa and a further 15-20 second generation hybrids are at advanced stages of testing.

Funding institutions: None (self-sustaining).
