1. Opaque endosperm-H. Endosperm similar to o₁ and o₂. Classification good in white dent stocks. Seed segregate 75% normal (O_H), 25% opaque (o_H). All O_H seeds produce normal plants while all o_H seeds produce dwarfish, yellow-green striped, abnormal leaved plants which die in four weeks under field conditions. Some seedlings of o_H lived two months in greenhouse but never got over 5 inches tall. Germination of o_H seed approximately 50%.
