Definitions

  • the first mentioned novel characteristic is desirable in order to maintain strong, sturdy root stock during the life of the commercial fruit bearing variety which is budded or grafted onto the seedling; the second characteristic, as above, making possible faster and more accurate suckering-by reason of the readily visible blood or red leavesof a seedling after the budding or grafting thereon of the commercial fruit bearing variety.
  • a further distinctive characteristic of the present variety of peach tree is that its seeds produce excellent nursery stock in that most of the resultant seedlings are straight, upright, and very uniform in growth. Such growth is advantageous-in root stock seedlings-as it facilitates easy and ready budding and other handling in the nursery.
  • a still further distinctive feature of the present variety of peach tree is that the seeds have an excellent germination ratio relative to failures; this being of economical advantage to the nurseryman who grows the seedlings for root stock use.
  • An additional feature of the present variety of peach tree is that it is a regular and productive bearer under normal agricultural care, and the fruit is freestone, which makes it possible to effect easy removal of the seeds for subsequent use in the propagation of root stock seedlings.
  • Fig. 1 is an elevation of a pair of the fruit of the instant variety; one of such fruit being in sectional eleva- 10 tion with the stone exposed.
  • Fig. 2 is an elevation of a twig and leaves, in fall growth, of a mature tree.
  • Fig. 3 is an elevation of a twig and leaves, in spring growth, of a mature tree.
  • Fig. 4 is an elevation of one of the root stock seedlings, in spring growth, produced from a seed of the present variety.
  • Fig. 5 is an elevation of one of the root stock seedlings, in fall growth, produced from a seed of the present variety.
  • Fig. 6 is an enlarged fragmentary elevation showing a sucker twig and leaves, in enlargement, of one of said seedlings at the time of suckering.
  • Tree Medium size. Form and density controlled by pruning. Productive and regular bearer under normal orchard care.
  • Trunk Medium stocky; medium shaggy. Branches: Slender; fairly smooth; brownish red-becoming grey on the older limbs.
  • the seedlings, grown from the seeds of the present variety, as shown in Figs. 4 and 5, and the suckering growth thereof as shown in Fig. 6, are predominately 5 characterized by the blood or reddish color of the leaves.
  • Average length.--l average breadth 1"; average thickness- F0rm.-Obovate.
  • Seedlings produced from seeds of the present variety have resistance to nematode infestation at least as high as theS-37 (United States Plant Patent No. 904) root stock peach variety, but which seedlings are advantageously distinct by reason not only of the blood or red leaves, but also the straight, upright, and uniform growing habit of most of such seedlings.
  • the blood or red leaves of the seedlings contribute substantially to the ease of suckering, for the reason that the parts to be removed from the root stock, after the commercial fruit variety is budded thereon, can be readily visually observed and distinguished.
  • the straight, upright, and uniform growing habit of the seedlings permits of easier budding, and more convenient handling by the nurseryman.
  • Seedlings of the present variety have been grown by me in extensive comparative tests, and under like growing conditions, with a number of other varieties, such as:
  • PI l4l204-D3836 PI 135994-13 6-32; PI l41204- D3837; PI 135994E6-32; P1 141202-D4030; PI l35994E8-4l; PI 135994-E8-38; PI 141202- 1340-29.
  • seedlings of the present variety 0 are at least as resistant to nematode infestation as the most resistant of any of the others, as above, and in addition shows better habits of growth, coupled with the red or blood leaf characteristic.
  • the seedlings of no other red or blood leafed variety approached the seedlings of the present variety in its resistance to nematode infestation.
  • a new and distinct variety of peach tree as illustrated and described, characterized by regular and productive bearing of freestone fruit Whose seeds have an excellent ratio of germination relative to failures, and which seeds produce seedlings-for root stock-which are highly resistant to nematode infestation, and a great percentage of said seedlings being blood or red leaved; the variety being further characterized by a high ratio of germination of the seeds, and a straight, upright, and uniform habit of growth of most of the resultant seedlings.
