Abstract

"Almost every fall, hard freezing weather in one or more sections of the United States catches the corn crop in an immature condition and injures or destroys the ears for use as seed. The latest and sappiest ears are often killed, while other ears, somewhat drier, have but a portion of the kernels killed. Frequently there are some ears so mature and dry that they are not injured or but slightly injured. Under such circumstances the uninjured ears are suitable for seed. By inspection they can be separated from the green ears that were killed. However, some of the ears that appear mature and sound have been killed or badly injured. To separate these ears from those that give a good germination, it is necessary to test the germination of a few kernels from each ear. The rag doll has proved a convenient and satisfactory way of making these germination tests. An effective method of making and using the rag doll is here described." -- p. 2
