From 1976 to 1988, 63 grain maize inbred lines and selections derived from synthetic and open-pollinated varieties were rated for their resistance to leaf feeding (antibiosis) and their tolerance to plant damage (stalk breakage) at harvest by the univoltine European corn borer, Ostrinia nubilalis (Huebner). They were also evaluated for their maturity in Quebec. A number of lines were resistant to leaf feeding but had severe plant damage resulting from stalk breakage at harvest, and vice versa. Some lines were considered resistant in their country of origin but showed intermediate resistance and/or some susceptibility in Quebec. The yield and borer attack of 119 inbreds or breeding lines of the International Working Group on Ostrinia (IWGO) trials are herewith reported
