N547 germplasm line (Reg. no. GP-367, PI 615526) was released by the Agriculture Research Division, Institute of Agriculture and Natural Resources, University of Nebraska, on 24 Aug. 1999. N547 is a yellow endosperm maize inbred germplasm with resistance to stalk and shank tunneling damage caused by the second generation of the European corn borer (ECB) Ostrinia nubilalis (Hubner).
N547 was derived by selfing a selected full-sib family from MBITA, a tropical population developed by CIMMYT, Mexico. MBITA was created to recombine sources of resistance to temperate and subtropical stalk borers. These insects included ECB, southwestern corn borer (SWCB) Diatraea grandiosella (Dyer), sugarcane borer (SCB) D. sacharallis (F.), spotted stem borer Chilo partellus Swinhoe, pink stem borer Sesamia calamistis Hampson, sugarcane borer (African) Eldana saccharina Walker, and African maize stalk borer Busseola fusca (Fuller) (Smith et al., 1989).
