Organized by principles rather than by crops, allowing the instructor to build the teaching system from simple concepts to complex programs. Covers such topics as: breeding objectives that introduce the student to the concept of program development by objectives rather than by individual crop species; program design and management; and new developments in scientific investigations, including wide genetic transfer and tissue culture. Questions to aid the student in understanding genetic principles are given at the end of several chapters. A glossary of important terms is also included.  aBotany
