Abstract

Aim: To evaluate effectiveness of the measures that was adopted by KEPHIS through seed certification process and establishment of volumes as well as percentage of rejections at different levels in the certification chain.

Materials and Methods: A combination of Sugarcane mosaic virus (SCMV) and Maize chlorotic mottle virus (MCMV), which are vectored by aphids and thrips, respectively. Seed samples were taken before seed dressing for laboratory test to ensure the lot is free from MLND. Imported seeds were also tested for MLND before being accepted into the country. Furthermore, there have been concerted efforts by breeders and researchers to develop and screen maize lines for resistance to MLND.

Results: Maize is the main staple food in Kenya and it resulted in the amendment of seed certification protocol which included testing of seed. In consultation with seed stakeholders, KEPHIS incorporated guidelines for MLND inspection in maize seed certification program. Other strategies that have been put in place include control of vectors and use of certified seed which are free from MLND.

Conclusion: Amendments in seed certification program that were implemented in Kenya have led to drastic reduction of MLND. It is further hoped that resistant maize lines from the breeding program will further support the effort to manage the disease.
