STARCH from the endosperm of mature corn, Zea mays L., may vary in the ratio of amylopectin to amylose. The total endosperm starch of commercial dent hybrids consists of approximately 73% amylopectin and 27% amylose. Other proportions are possible, since the starch fraction is conditioned by a number of major genes. Cameron (4), Kramer and Whistler (11), and Dunn et al. (8) reported the effects of du, su^suz, and sif on amylose content. In each instance, amylose content was negatively correlated with total starch production. However, Deather-
