A project on breeding for early maturing corn varieties undertaken at the DA-Ilagan Experiment Station, Ilagan, Isabela, to develop corn varieties adapted to the drought and flood prone area of the Cagayan Valley and similar producing corn areas in the Philippines. After several seasons of improvement, evaluation and selection of corn populations composing of local and foreign materials, two (2) corn varieties, IES Early white and IES Early yellow had been formed. Based on preliminary trials it can be stated that these varieties yielded significantly higher than the Native White Flint used as check and matured approximately at the same time than the check. They also yielded comparatively equal to the improved OPV check (IES Cn 1, a Seed-board variety)
