Abstract:
Studies on a large number of self-fertilized ears of Reid Yellow Dent, Illinois High Yield, and Illinois Two Ear corn brought out the following facts: 1. Percentage of seed and seedling abnormalities varied greatly for these varieties, Illinois High Yield showing about three times the percentage shown by Reid Yellow Dent and Illinois Two Ear. 2. There appears to be a slight relation between the general appearance of the ears and the percentage of seed and seedling abnormalities, the better appearing ears showing the smaller percentages. 3. Entire absence of chlorophyll (albinism) was the most frequent chlorophyll defective type found followed by pale green, Japonica, virescent, yellow, lineate, and fine striped in the order named.
