Variation in Corn Seed
Mr. Burbank finds material for most of his experiments in variations as to one quality or another that appear among plants of the same species. It may or may not be necessary to accentuate variaton by hybridizing experiments. The range of variation that may be shown in the seed of a single species is illustrated in this lot of kernels of corn, which show surprising diversity in shape, size, and color. Numberless new varieties could be developed through selective breeding from such a lot of seed as this.
