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 ...
Genetic distance and hybrid value in tropical maize under P stress and non stress conditions in acid soils
An emphasis in maize breeding for areas with acid soils is the development of varieties with tolerance to P-deficiency plus high yield potential in acidic as well as normal soils. This study was carried out to assess the ...
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 ...
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 ...
Genome‑wide association analysis reveals new targets for carotenoid biofortification in maize
Key message Genome-wide association analysis in CIMMYT’s association panel revealed new favorable native genomic variations in/nearby important genes such as hydroxylases and CCD1 that have potential for carotenoid b ...
Conservation tillage or residue conservation? an evaluation of residue management in Mexico
The key to conservation tillage is the use of crop residues as mulch. However, there is some confusion over the term conservation tillage, among other things, because too much emphasis has been placed on tillage. Since ...
