In some unknown way there was produced in this plant a red pigment not formed in other sunflowers. From the seeds of this plant there were developed other plants having red pigment in their flowers. Evidently the new character is inherited and these sunflowers have a chemical constitution which enables red pigment as well as yellow to be formed. The sudden appearance of the simflower with the red pigment is an example of mutation. Individuals that first show new characters are caUed mutants (Latia: mutare, to change). What the plant breeders have long known as " sports " are the rare mutants in which notable changes have occurred. They show new characters, and these characters are in- herited. Consequently, their discovery is of the greatest importance. The Concord grape was a mutant selected from among many seedlings, the others of which showed only the usual variations. The many modern varieties of tomato have been developed. Fig. 141. Varieties derived from the wild cabbage (F), a native plant of Europe.
