Breeding for drought and nitrogen stress tolerance in maize: from theory to practice
Targeted initially for maize breeders in sub-Saharan Africa, the content is based on a successful approach developed at CIMMYT for improving the tolerance of maize to drought and low nitrogen stress. Intended as a supplement ...
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 ...
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 ...
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 ...
Gene action determining Phaeosphaeria leaf spot disease resistance in experimental maize hybrids
Phaeosphaeria leaf spot (Phaeosphaeria maydis Henn.) has the potential to cause substantial yield losses in maize. Maize is grown by small-scale farmers without fungicides; hence there is need to breed for resistance in ...
Construction of a SSR linkage map and mapping of quantitative trait loci (QTL) for leaf angle and leaf orientation with an elite maize hybrid
Maize (Zea mays L.) breeders have begun selecting for more compact plants for higher density planting in order to increase yield per unit area. Leaf angle and leaf orientation are very important traits affecting maize plant ...
