A corn breeding project was conducted at the La Granja National Crop Research and Development Center, La Carlota City, Negros Occidental [Philippines] which aimed to develop high yielding corn varieties that have uniform maturity, resistance to lodging as well as to pests and diseases and adapted to local argo-climatic conditions. The project involved the collection and evaluation of parent materials, hybridization and selections, and regional yield trial. Based on the results of the Regional Yield Trial (RYT) in 11 cooperating stations of the National Cooperative Testing (NCT), promising line LG5 had a mean yield of 5.81 t/ha. It performs well during the dry season and was observed to be moderately resistant to corn borer, earworm, stalk rot and rust, and highly resistant to downy mildew. Plant height ranges from 204 to 224 cm. Due to its outstanding performance in the Regional Yield Trial across locations, the Corn and Sorghum Technical Varietal Improvement Group recommended LG5 to become a variety, hence on November 12, 1997, the National Seed Industry Council (NSIC) approved it as PSB Cn 97092, a commercial corn variety known locally as BPI LG Composite 5
