The corn breeding program of which the present work is a part was started in 1949 by Dr. D. L. Umali. As sources of yellow-endosperm inbreds he chose a high-yielding native strain called the College Yellow Flint, and the Cuban Yellow Flint, which was introduced from Cuba by Dr. J. M. Capinpin in 1935. Ten selected inbred lines from a strain of Philippine corn (College Yellow Flint) and six selected inbred lines from a strain of Cuban corn (Cuban Yellow Flint) introduced from Cuba and found reasonable adapted under Philippine conditions in general, were crossed in all possible combinations. The Cuban Yellow intracrosses did not yield well.
