Figure 11.—High-ear and low-ear breeding plots in the fifth generation. Figure 11 shows the two plots in the fifth generation. The white tape shown in the picture was fastened at the middle of the ears in the front row. Photographs 12 and 13 were taken the same day and they give a closer view of these two plots. It will be noticed that a remarkable difference in the size of the plant has been induced by selecting simply with reference to height of ear. With this difference in size of plant there is a notable difference in time of maturity between these two strains so that at the time of tasseling the low-ear plot is now about a week in advance of the high-ear plot. It is of especial interest to note that in spite of the much smaller size of the low-ear plant, in production of grain this strain is thus far yielding fully as well as the high-ear strain. This is very significant, for one of the most important questions before the attention of the corn growers and corn breeders today is that of maturity. The demand is for grain that will grade better in the market, keep better in storage, ship better in exportation, ger- minate better when planted, and our problem is the difficult one of inducing earliness without sacrificing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Missouri.
