Methods of crop breeding have undergone
major changes, and a range of technologies is
improving the rate and success of crop improve-
ment in some breeding programs, but these have
yet to be widely adopted. Contributions are be-
ing made through new selection strategies that
are informed by sophisticated genetics, the use
of computers to track and manage field trials, and
biometric methods for field-trial design and as-
sessment of interactions between genotype,
environment, and management (13).
