Abstract: The present invention relates to new Zea mays plants which are resistant to both Western Corn Rootworm (WCR) and European Corn Borer (ECB) and do not express an insecticidal protein derived from Bacillus thuringiensis. The invention is also directed to hybrids, progeny and seeds of those plants.

Abstract: 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.
