Marker Assisted Selection: a Fast Track to Increase Genetic Gain in Plant and Animal Breeding? Session I: Mas in Plants

The development of molecular techniques for genetic analysis has led to a great increase in our knowledge of cereal genetics and our understanding of the structure and behaviour of cereal genomes. These molecular techniques, in particular the use of molecular markers, have been used to monitor DNA sequence variation in and among the species and create new sources of genetic variation by introdu...

Within the framework of our cotton breeding program, we are using molecular markers to improve the efficiency of the introgression of fiber quality traits into a favorable genetic background. This effort relies on i) the development of a saturated genetic map of the cotton genome, ii) the identification of fiber quality QTLs, and iii) the marker-assisted introgression of favorable genomic regio...

Designs used for detecting QTL in livestock vary from experimental backcross and F2 populations to half-sib designs that use existing family structures within a commercial population. This contribution discusses how the initial design in which the QTL are detected affects: a) the implementation of MAS and b) the fine mapping of the QTL. The optimal approach depends on the livestock species and ...

Selection under the infinitesimal model Standard animal breeding techniques have been largely successful in improving the performance of domestic animals in the last century. The success of these techniques finds its roots in the theoretical work of Fisher and Wright who showed how selection, migration and mutation could be derived from the simple Mendelian laws. All that theory was then transf...
