A modified backcrossing procedure incorporated desirable morphological characters into a dent corn inbred line Oh45, resistant to leaf feeding of first-brood European corn borer (Pyrausta nubilalis (Hbn.)). Outerossing, to a corn borer susceptible single cross, and then selfing with selection fixed the desired characters. With another backcrossing to the inbred line and continued selling, three lines designated as Oh45A, Oh45B, and Oh45C were developed as resistant to first-brood leaf feeding as The recurrent parent. One of these lines may be released in the future as a partial replacement for Oh4.5.
