Maize (Zea mays L. ssp. mays) was domesticated from one wild species ancestor, the Balsas teosinte (Zea mays ssp. parviglumis) about 9000 years ago. Higher levels of gene diversity are found in teosinte taxa compared to maize, following domestication and selection bottlenecks. Diversity in maize ...

Gene flow among different teosinte taxa and into the domesticated maize gene pool
The quest for precise and rapid phenotyping of germplasm is increasing the interest of breeders and physiologists in the application of remote sensing techniques in maize breeding. Twenty-four drought-tolerant maize inbred lines were crossed using a modified North Carolina II mating scheme to gen...

Demand for livestock products has been increasing through much of the semi-arid
tropics and will likely continue to increase along with the use of purchased feedstuffs. As
smallholder livestock systems evolve and become more market oriented, the type of diets
fed to livestock may change and the i...

Southern corn leaf blight (SCLB), caused by the fungus Bipolaris maydis, is a disease that significantly affects maize productivity across the globe. A detached leaf assay (DLA) was developed to rapidly assess maize resistance to SCLB. Several experiments were conducted to: (i) identify a highly ...

Normalized difference vegetation index (NDVI) is a non-destructive measure of green vegetation growth or above ground biomass of a crop. NDVI may also be used to evaluate traits such as early vigour and stay green which are important for adaptation to drought stress. In the present study, the rel...

Abstract Introduced maize (Zea mays L.) germplasmcan serve as sources of favorable alleles toenhance performance in new maize varieties andhybrids under drought stress conditions. In the presentstudy, the combining abilities of 12 exotic maizeinbred lines from CIMMYT and 12 adapted maizeinbred li...

Marker-assisted recurrent selection (MARS) is a breeding method used to accumulate favorable alleles that for example confer tolerance to drought in inbred lines from several genomic regions within a single population. A bi-parental cross formed from two parents that combine resistance to Striga ...

Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa
The objective of marker assisted recurrent selection (MARS) is to increase the frequency of favorable marker alleles in a population before inbred line extraction. This approach was used to improve drought tolerance and grain yield (GY) in a biparental cross of two elite drought tolerant lines. T...

Maize is the most important cereal food
crop is sub-Saharan Africa though yields are below
their potential. Among the factors which limit yield,
drought stress is one of the most pervasive. The ability
of a crop to produce grain under drought (water) stress
is governed by many factors including n...
