The preservation of different plant varieties and valuable species is an important prerequisite for successful plant breeding. All relevant techniques required to maintain viable plant cells or organs in vitro over extended periods of time are presented in Genetic Preservation of Plant Cells in Vitro. A maximum level of genetic stability during storage is taken as an overriding priority in each of the techniques. Each chapter is written as a "hands-on" practical guide and presents procedures that can be adapted to suit individual laboratory conditions and modified to best suit the particular material beeing preserved.
