Cross breeding

Cross breeding
Breeding method using directed crossing to generate higher variability, applied for both self-pollinating and out-breeding species.
Sometimes used for allogamy.

Selection method for self-pollinating species in cross breeding. After making the initial cross the segregating progenies are propagated till F4 to F6 without selection.

This is not to say that cross breeding does not take place at all, simply that it has become negligible. Generally, the hybrid individuals are less capable of successful breeding than pure-bred individuals of either species.
