IPB Var 4 (Zea mays), a composite was tested experimentally as XV-4 and was subsequently approved for release by the National Seed Industry Council (NSIC), formerly the Philippine Seed Board (PSB), in 1991. This composite was developed by the Corn Breeding Group, Cereals Division, Institute of Plant Breeding (IPB), College of Agriculture (CA), University of the Philippines Los Banos (UPLB). IPB Var 4, is a white flint composite variety, and is moderately resistant to first generation Asiatic corn borer (Ostrinia furnacalis) and moderately resistant to drought. This composite is a product of a cross between IPB Var 2 and Antigua Gpol which is an established source of reistance to first generation corn borer. According to the corn National Cooperative test (NCT) conducted, this composite has an average yield of 4.89 t/ha with maturity of 105 to 110 days after planting. It attains an average plant height of 207 cm and an ear height of 90 cm. Kernels made into grits have excellent quality and is highly acceptable. Breeder seeds of this open pollinated variety (OPV) are maintained by the Cereals Division, IPB, CA, UPLB, and 52 kernels packets will be distributed upon request. Seeds for commercial production are available at the IPB-Central Mindanao University (CMU) Experiment Station, Musuan, Bukidnon, Philippines. Appropriate recognition of the original seed sources of this OPV is required of all recipients of the seed if used to develop a new population, parental line, or hybrid
