But little effort has been made, as the histories of its varieties show, to breed peaches. All but a very few varieties have come from chance seedlings. Peaches were grown from seed for centuries and many types now come true when seeds are planted. After budded trees became the vogue, until Mendel's great discovery, breeding the peach consisted in selecting an occasional meritorious tree, multiplying it by budding and, if it had pronounced merit, turning it over to a nurseryman for the trade. The art progressed no further because selection was thought to be the fundamental process in improving plants and breeders preferred to work in fields where the harvests were more immediate than in tree-fruits. Now that plant-breeding centers around controlled hybridization, plants propagated vegetatively should receive quite as much attention as those grown from seed. Mendel has opened the door to intimate familiarity with some of the fundamental phenomena of hybridization, and, despite the difficult and complex literature the professionals are imposing on the art, chiefly discussions of methods and disputations about principles, the layman finds Mendelian laws easy to put in practice; and peach-breeding is certain to go forward in leaps and bounds as the irresistible fascination of the subject seizes peach-growers. Meanwhile, as a foundation for future work, it becomes highly important to know how the varieties we have came into existence. The known histories of the many diverse kinds of peaches show that this fruit has been improved almost wholly through new varieties by chance hybridization--self-fertilized seed, selection and mutations are almost negligible factors. The following are the data: No case is recorded in _The Peaches of New York_ of a variety known to have come from a self-fertilized seed. The seed parent is given for 214 varieties; the seed and pollen parents of 37 varieties. But 4 varieties are reported to have come from bud-mutations. Of chance seedlings, sorts from seed with neither parent known, there are 161. The origins of 1765 of the varieties described in _The Peaches of New York_ are unknown. The total number of peaches described is 2181. CHAPTER IV PEACH-GROWING IN NEW YORK The history of the peach, whether narrative or natural, shows that this fruit succeeds commercially only in restricted areas under special soil and climatic conditions. In the United States, as we have seen, the peach-industry has sprung up in a dozen or more distinct geographical regions, three of which are in New York. In discussing peach-growing in New York we must, first, determine the boundaries of its peach-regions; second, show the relative importance of the peach-industry in each; and, third, note the determinants that make favored parts of the State peach-regions.
