Abstract
THE idea of combining the desired qualities of two distinct genotypes is old and universally appreciated. The genetic information can be brought together in two ways: within the same zygote through hybridization; or, for example, in higher plants, by grafting the stem of a superior fruit onto a particularly hardy root system. It is increasingly clear that the phenomenon of grafting (like hybridization) is a common natural process in which the root systems (and stems) of genetically distinct individuals become functionally interconnected.
