SELECTION OF PARENTS In the great majority of cases, indeed, nothing of real importance could be accomplished were the experiment carried no further than the first mating or hybridizing of the individuals selected to act as parents. Yet, on the other hand, right selection here is the condition of all future suc- cess. Some of Mr. Burbank’s most striking results have been attained through the hybridizing of species that were in many respects widely diver- gent. In particular, he brought together species from widely separated geographical territories, and thus gave opportunity for the blending of di- versified racial strains. Examples in point are furnished by the vast numbers of experiments with members of the race of plums. Almost at the outset of his experi- mental work Mr. Burbank imported plums from Eastern Asia, and began crossing them with var- ious species of plums from Europe as well as those indigenous to America.
