Comparative analysis of carotenoid and tocopherol compositions in high-oil and normal maize (Zea mays L.) inbreds
Among staple crops, maize has a high amount of carotenoids and tocopherols, which have a number of beneficial effects on human health. The former is the main dietary precursor of vitamin A. The latter is an essential ...
Combining ability amongst CIMMYT's early maturing maize (Zea mays L.) germplasm under stress and non-stress conditions and identification of testers
CIMMYT (International Maize and Wheat Research Institute) Zimbabwe’s early maturing maize program, which aims to supply seed to approximately 4 million hectares of maize area in eastern and southern Africa, lacks ...
Combining ability among twenty insect resistant maize inbred lines resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of ...
Development of a seed DNA-based genotyping system for marker-assisted selection in maize
Leaf collection from the field, labeling and tracking back to the source plants after genotyping are rate limiting steps in leaf DNA-based genotyping. In this study, an optimized genotyping method using endosperm DNA sampled ...
Detection of Bacillus thuringiensis genes in transgenic maize by the PCR method and FTA paper technology
We optimized the PCR method to detect genetically engineered Bacillus thuringiensis (Bt) maize in open quarantine fields in Kenya. Many factors affect the extraction of the DNA from plants, such as the amount of tissue ...
A method for combining molecular markers and phenotypic attributes for classifying plant genotypes
Abstract Classifying genotypes into clusters based on DNA fingerprinting, and/or agronomic attributes, for studying genetic and phenotypic diversity is a common practice. Researchers are interested in knowing the minimum ...
Divergent selection for resistance to maize weevil in six maize populations
Maize weevil (Sitophilus zeamais Motschulsky) is an important pest of maize (Zea mays L.) in the tropics, causing serious losses for many resource-poor farmers who store grain on-farm for use as food and seed. This study ...
Simulation Experiments on efficiencies of gene introgression by backcrossing
Designing a highly efficient backcross (BC) marker-assisted selection (MAS) experiment is not a straightforward exercise, efficiency being defined here as the ratio between the resources that need to be invested at each ...
Specialty maize: global horticultural crop
The growth in high-value agriculture worldwide is partly driven by rising incomes, urbaniza tion, and perhaps changing preferences. As income rises, the share of the food budget allocated to starchy staples declines relative ...
