An inbred corn line, designated 6RT321, is disclosed. The invention relates to
the seeds of inbred corn line 6RT321, to the plants of inbred corn line 6RT321
and to methods for producing a corn plant, either inbred or hybrid, by crossing
the inbred line 6RT321 with itself or another corn line. The invention further
relates to methods for producing a corn plant containing in its genetic material
one or more transgenes and to the transgenic plants produced by that method and
to methods for producing other inbred corn lines derived from the inbred 6RT321.
