| Abstract: |
A peach tree, denominated "David Sun", producing very firm yellow fleshed cling fruit having a skin of very high dark red to bright yellow color ready for harvest about June 1 and reaching full maturity about June 4. |
| Claim: |
Having thus described and illustrated my new variety of peach tree, what is claimed as new and desired to be secured by Letters Patent is:
1. A new and distinct variety of peach treesubstantially as illustrated and described broadly characterized by its cling fruit having a skin of very high dark red to bright yellow color, very firm yellow flesh having excellent holding quality on the tree, as well as its shipping and storagequality, and ripening for harvest about June 1 and reaching full maturity about June 4 in the San Joaquin Valley of California. |
| Description: |
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of peach tree, denominated "David Sun", which is a newly found seedling of the "June Lady" peach tree having cling fruit of very high dark red to bright yellow color, very firm yellowflesh and good flavor reaching picking ripeness about June 1 and full maturity about June 4 at Del Rey, Calif.
A variety of attributes can enhance the commercial value of tree fruit. Such characteristics as early ripening, bright skin color, large size, good flavor, low acidity, tight flesh, keeping quality and the like may all play a part in determiningthe market value of tree fruit. It is, however, quite unusual for tree fruit to excel in more than a few such characteristics.
There are other characteristics which are more directly related to the commercial value of the trees themselves in that the production of the tree fruit is made easier. Thus, such characteristics as tree size, vigor of growth, the holdingquality of the fruit on the trees, resistance to breakdown in the fruit and in the trees themselves, ripening dates, storage and shipping quality and the like may make certain varieties of trees more desirable than others. Again, it is quite unusual fortree varieties to excel in more than a few such characteristics.
The variety of peach tree of the present invention is distinct from other varieties of peach tree known to the applicant in that it excels in a prodigious number of these characteristics. The fruit ripens early and holds very well on the tree,as well as having a long storage life. The fruit is of the cling type and will not breakdown on its suture or apex. Furthermore, the fruit is distinctive in that it has a very high color with very firm yellow flesh having good flavor and low acidtaste.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The new variety of peach tree of the present invention was discovered by me in 1977 and is a newly found seedling of the "June Lady" peach tree. Seeds of the "June Lady" peach tree were planted in the nursery of H. P. Metzler & Sons at 5286South Del Rey Avenue, Del Rey, Calif. 93616 in 1975. The first fruit of the variety of the present invention was observed in 1977 and its distinctive characteristics discovered at that time.
The new variety was asexually propagated under my direction at H. P. Metzler & Sons in 1978 by grafting a number of seedlings with scions from the newly discovered seedling. The grafted seedlings were in 1978 planted in a test nursery of H. P.Metzler & Sons at Del Rey, Calif. The seedlings of the new variety were observed in the test nursery over several growing seasons and tree and fruit characteristics resulting from such asexual reproduction proved to be identical to those of the originalseedling of the new variety.
SUMMARY OF THE NEW VARIETY
The new variety of peach tree of the present invention is characterized by its cling fruit having a skin of very high dark red to bright yellow color, very firm yellow flesh and good flavor reaching picking ripeness about June 1 and full maturityabout June 4 at Del Rey, Calif., the fruit being still further characterized by its excellent holding quality on the tree and by its excellent storage and shipping quality.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph of four mature fruit of the instant variety, one positioned to show the side having the suture, a second positioned to show the stem cavity, a third positioned to show the apex and a fourth slicedalong its longitudinal axis with the pit left in place. A representative twig is also shown in the photograph with the upper sides of characteristic leaves exposed. The lower side of a characteristic leaf is also shown.
DETAILED DESCRIPTION
Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following characteristics were observed under the ecological conditions prevailing at the nursery of H. P. Metzler & Sons at Del Rey,County of Fresno, State of California and is an outlined description thereof. All major color code plate identifications are by reference to the Color Name Chart of the Inter-Society Color Council, National Bureau of Standards.
