Corn is one crop where the industry and the farmers are imperiled. This is because the area devoted to this most important feed grain and the second most important food crop is decreasing. Furthermore, the Philippine government is bound by the World Trade Organization agreement that would allow corn importation among member countries when the need arises. These situations accentuate the need to improve our productivity. One approach is to plant more of our farms to hybrids. With this realization, the Bureau of Agricultural Research and the Philippine Council for Agriculture, Forestry and Natural Resources Research and Development jointly supported a 5-year breeding project of the Institute pf Plant Breeding to develop high yielding and stress-tolerant hybrids. After two years of the project, a total of 7,185 entries were evaluated already by the Entomology, Pathology and Physiology Laboratories. Such extensive work resulted to identification of 87 lines with resistance to downy mildew, 33 to bacterial leaf sheath blight, 13 to bacterial stalk rot, 187 to corn borer and 126 to water stress. Seven new entries are now undergoing National Cooperative Test of the National Seed Industry Council
