This book begins by analyzing how crop science emerged and provides a snapshot of the field's controversial present by exploring progress being made with genetically engineered plants. It then discusses methods for preparing media, creating solutions and dilutions, and accomplishing sterile culture work. It also investigates common methods for visualizing and documenting studies and quantifying responses of tissue culture in research, and delivers the essential foundation of plant tissue culture, introducing the three types of commonly used culture regeneration systems. The final section integrates propagation techniques with other methodologies for the modification of germplasm.
