This book provides an overview of the rapidly developing integration and interdependence of quantitative genetics, genomics, bioinformatics and their application to plant breeding. Chapters have been developed from a symposium held in Baton Rouge, Louisiana, in March 2001, although additional contributions have also been commissioned especially for this volume. The main topics covered include: quantitative trait loci (QTL) mapping, genomics, bioinformatics and marker-assisted selection; tissue culture and alien introgression for crop improvement; and advances in genotype by environment interaction/stability analysis.
