Big String Nectarines
The nectarine is in effect a smooth skinned peach. It is believed that the two fruits are really identical superficially, and have only somewhat recently been modified through selective breeding. Nevertheless there are obvious differences in the peach and the nectarine, and there is opportunity for interesting experiments in crossbreeding. Mr. Burbank has taken full advantage of these opportunities, and this picture shows one of his many interesting results.
