1. A maize plant of a cultivated maize plant variety comprising a recombinant chromosomal segment that comprises a first allele at the Ht2 locus that confers resistance to NLB and a second allele at the HtN locus that confers resistance to NLB, wherein said recombinant chromosomal segment is flanked in the genome of said plant by marker locus Q-NZMAY009401770 (SEQ ID NO: 1) and marker locus Q-NZMAY009430172 (SEQ ID NO: 16) on chromosome 8, wherein said first allele comprises marker locus Q-NZMAY009401770 (SEQ ID NO: 1) or marker locus Q-ZMHt2 (SEQ ID NO: 6) and wherein said second allele comprises marker locus Q-NZMAY009238970 (SEQ ID NO: 11) or marker locus Q-NZMAY009430172 (SEQ ID NO: 16), and wherein said first allele and said second allele are configured in cis linkage on said chromosomal segment.
