Technical Abstract: The study of crop evolution, origins, and conservation entails the assessment of genetic variability with and between populations and species at different genetic, evolutionary, and taxonomic hierarchical levels. Molecular biology has greatly increased the amount of data and computational intensity of population genetic and phylogentic systematic analyses. Numerous methods of analysis are available, several of which are used in this volume. This appendix is not meant to be exhaustive, but rather the describes some of the commonly used analysis methods that are used in this volume. For those who like more information, a list of suggested reading and links are provided.
