Maize, the main dietary staple in Kenya, is one of the crops most susceptible to contamination by aflatoxin. To understand sources of aflatoxin contamination for home grown maize, we collected 789 maize samples from smallholder farmers’ fields in Eastern and South Western, two regions in Kenya re...


Mahuku, George S.Nzioki, H.S.Mutegi, C.Kanampiu, F.Narrod, C.Makumbi, Dan[Pre-harvest management is a critical practice for minimizing aflatoxin contamination of maize]Pre-harvest management is a critical practice for minimizing aflatoxin contamination of maize

A survey was conducted in 2013 to establish total aflatoxin and total fumonisin in maize, as well as farmers’ practices relating to maize cultivation and awareness of mycotoxins, in three villages of Babati District, northern Tanzania. Quantification of total aflatoxin and fumonisin was done usin...


Nyangi, C.Beed, Fen D.Mugula, J.K.Boni, S.Koyano, E.Mahuku, George S.Sulyok, M.Bekunda, Mateete A.[Assessment of pre-harvest aflatoxin and fumonisin contamination of maize in Babati District, Tanzania]Assessment of pre-harvest aflatoxin and fumonisin contamination of maize in Babati District, Tanzania

Tar spot complex (TSC) is a highly destructive disease of maize found in some countries in America. Identification of TSC resistant germplasm and elucidating the genetic mechanism of resistance is crucial for the use of host resistance to manage this disease. We evaluated 890 elite maize inbred l...

Fusarium ear rot (FER) incited by Fusarium verticillioides is a major disease of maize that reduces grain quality globally. Host resistance is the most suitable strategy for managing the disease. We report the results of genome-wide association study (GWAS) to detect alleles associated with incre...


Chen, J.Shrestha, R.Ding, J.Zheng, H.Mu, C.Wu, J.Mahuku, George S.[Genome-wide association study and QTL mapping reveal genomic loci associated with Fusarium ear rot resistance in tropical maize germplasm]Genome-wide association study and QTL mapping reveal genomic loci associated with Fusarium ear rot resistance in tropical maize germplasm

Aspergillus flavus induced ear rots and subsequent contamination of maize (Zea mays L.) by aflatoxin is a serious food safety issue, especially in developing countries where the crop is mostly cultivated by smallholder famers for own consumption and income generation. A better understanding of th...


Garrido-Bazan, V.Mahuku, George S.Bibbins-Martinez, M.Arroyo-Bacerra, A.Villalobos-López, M.A.[Dissection of mechanisms of resistance to Aspergillus flavus and aflatoxin using tropical maize germplasm]Dissection of mechanisms of resistance to Aspergillus flavus and aflatoxin using tropical maize germplasm

Background Common rust, caused by Puccinia sorghi, is an important foliar disease of maize that has been associated with up to 50% grain yield loss. Development of resistant maize germplasm is the ideal strategy to combat P. sorghi. Results Association mapping performed using a mixed linear mode...
