Stacked insect resistant and herbicide tolerant maize produced by conventional cross breeding of parental lines TC1507, MON 810, and NK603.  Resistance to lepidopteran insects is conferred by expression of the <i>cry1F</i> and <i>cry1Ab</i> geners derived from <i>Bacillus thuringiensis</i>.  Tolerance to glufosinate ammonium herbcicide is derived from TC1507 from the phosphinothricin <i>N</i>-acetyltransferase encoding gene from <i>Streptomyces viridochromogenes</i>.  Tolerance to glyphosate herbicide is derived from event NK603, which expresses the CP4 EPSPS encoding gene from <i>Agrobacterium tumefaciens</i>.
