Line breeding occurs whenever closely related individuals are
intermated, such as full sibs, half sibs, and first cousins.  Line
breeding is an efficient breeding method for "fixing" the desired traits
in a relatively short period of time.  Line breeding results in each
succeeding generation becoming more homozygous as hybridizers continue
to line breed within a given line.  Line breeding can also lead to a
loss of vigor.  The most severe form of line breeding is
self-pollination.  Also undesirable traits can become fixed within a
given line.  However this can be overcome by maintaining a separate but
related line and crossing between the two.

Hope this helps.
