Carrot (Daucus carota L.) is a white flowering plant in the family Apiaceae, and is native to temperate regions of Europe and southwest Asia. It is naturalized to North America and Australia. This book discusses the applications of biochemical and molecular markers for assessing the genetic diversity and phylogenetic relationships of carrot germplasm in order to provide developed technologies for crop improvement. This book is of interest to plant geneticists, plant breeders, researchers, and scientists.
