Considerable interest has developed in recent years in crucifers ("brassica"), particularly wild variations of these flowering mustard and cabbage plants, as these contain genetic material that may be cultivated for further evolution of superior crop varieties. Bringing together leading researchers, this book includes research on biology, breeding, and the genetic diversity of species" Brassicaceae, " It will explore possibilities of utilizing genes from wild variations into commercial agricultural crops. Chapters will include information on the evolution and phylogenies of crucifers, cytogenetics, biology, and sterility in crucifer species, and germplasm conservation.
