Loquat and Seeds
The wild loquat of Japan, the progenitor of all the cultivated varieties, bears a small fruit about the size of a very large cherry or small plum, nearly all skin and seeds. This figure suggests the improvement that has been produced in the fruit in a comparatively short time by selective breeding. All Mr. Burbank's trees are descended from a single tree bearing relatively large fruit imported from Japan.
