It poses serious limitations in increasing production of maize and losses in maize grain yield range from 18% to 44%. The work done on Economic Injury Level (ElL), the basis of resistance, genetic, biochemical and morphological have been reviewed. The essential components of breeding for borer resistance in maize have been discussed. As the resistance in. maize is polygenic and additive in nature, although the process may be slow, level of resistance in hybrids may be through development of resistant inbreds. For population improvement recurrent selection and alternate methods of selection are suggested by various researchers. The efforts on breeding for multiple borer resistant maize population (s) for Asian region are in progress. Development of transgenic plants protected from borer attack should also be explored for its control.Collection: CIMMYT Publications Collection
