Adoption of maize production technologies in Northern Tanzania
(SADC; CIMMYT; SACCAR, 1998)
The impact of maize research and extension in Tanzania's Northern Zone during the past 20 years was evaluated through a formal survey in 1995. Data were grouped into two major agroecological zones: the intermediate and the ...
Experiences with the biosafety regulatory system in Kenya during the introduction, testing and development of Bt maize
The introduction of genetically modified (GM) crops in Kenya is governed by a biotechnology policy, a biosafety law, and a biotechnology awareness strategy to enable research and development of GM crops. In addition, Kenya ...
Genotype by environment interactions and yield stability of stem borer resistant maize hybrids in Kenya
In a maize breeding program, potential genotypes are usually evaluated in different environments before desirable ones are selected. Genotype x environment (G x E) interaction is associated with the differential performance ...
Experiences in effective communication on transgenic technology in Africa - the case of the insect resistant maize for Africa (IRMA) project
The Insect Resistant Maize for Africa (IRMA) Project, aimed to improve food security through developing and deploying locally adapted stem borer resistant maize varieties using both conventional and biotechnology mediated ...
Grain yield, stem borer and disease resistance of new maize hybrids in Kenya
Evaluation of 30 maize hybrids for yield and resistance to stem borers and foliar diseases in four agro-ecologies in Kenya was conducted in 2009. There were significant differences among the hybrids in leaf damage, number ...
Combining ability of maize inbred lines resistant to Chilo partellus (Swinhoe) in the mid-altitude environment of Kenya
Gene action conditioning important traits in maize is useful to breeders in order to design appropriate breeding methods. A study was conducted to determine the combining ability of 10 maize inbred lines adapted to Kenya?s ...
