Effective grain storage : success stories 2010
Hierarchical multiple-factor analysis for classifying genotypes based on phenotypic and genetic data
A numerical classification problem encountered by breeders and gene-bank curators is how to partition the original heterogeneous population of genotypes into non-overlapping homogeneous subpopulations. The measure of ...
Conservation agriculture training 2010 : interview with a scientist 1
An Indian scientist speaks about his experience with conservation agriculture (CA) and how attending a 5 week-long course at CIMMYT expanded his understanding of CA concepts and practices.
The genetic dissection of quantitative traits in crops
Most traits of interest in plant breeding show quantitative inheritance, which complicate the breeding process since phenotypic performances only partially reflects the genetic values of individuals. The genetic variation ...
Sample size for detecting and estimating the proportion of transgenic plants with narrow confidence intervals
Detecting the presence of genetically modified plants (adventitious presence of unwanted transgenic plants, AP) from outcrossing species such as maize requires a method that lowers laboratory costs without losing precision. ...
Multifunctional crop trait ontology for breeders' data: Field book, annotation, data discovery and semantic enrichment of the literature
Background and aims Agricultural crop databases maintained in gene banks of the Consultative Group on International Agricultural Research (CGIAR) are valuable sources of information for breeders. These databases provide ...
Analysis and answers to frequently asked questions in quantitative trait locus mapping
QTL mapping is an important step in gene fine mapping, map-based cloning, and the efficient use of gene information in molecular breeding. Questions are frequently met and asked in the application of QTL mapping in practical ...
Molecular breeding in developing countries: Challenges and perspectives
Molecular breeding (MB) holds great promise for developing countries. However, the developing countries are hardly homogeneous in its implementation. Whilst newly industrialised countries routinely use several MB applications ...
Genetic analysis and characterization of a new maize association mapping panel for quantitative trait loci dissection
Association mapping based on the linkage disequilibrium provides a promising tool to identify genes responsible for quantitative variations underlying complex traits. Presented here is a maize association mapping panel ...
Efficiency of selective genotyping for genetic analysis of complex traits and potential applications in crop improvement
Selective genotyping of individuals from the two tails of the phenotypic distribution of a population provides a cost efficient alternative to analysis of the entire population for genetic mapping. Past applications of ...
