Claim:
1. Zea mays plant which is inbred and is resistant to both Western Corn Root Worm and European Corn Borer, wherein the plant does not comprise a gene expression cassette expressing a protein derived from Bacillus thuringiensis , and is at least 20% more resistant to Western Corn Root Worm and European Corn Borer as compared to Zea mays line NGSDRW 1 (SC2)C4-15-252, wherein the resistance is determined by use of a scale selected from the group of a 1-9 lodging rating scale and a 0-3 Iowa scale and compared to non-resistant control plants grown in the same environmental conditions, wherein the resistance to Western Corn Root Worm and European Corn Borer is detected by at least two single nucleotide polymorphisms (SNPs), and wherein the first SNP is an A/T nucleotide exchange located at position 197 cM_IBM_map on chromosome 5, and the second SNP is an A/C nucleotide exchange located at position 383 cM_IBM_map on chromosome 2.
