| Abstract: |
A peach tree, denominated "June Sun", producing yellow fleshed, semi-cling fruit having a skin of bright red to yellow coloration tenacious to the flesh ripening for harvest about June 8 to June 10, when ungirdled. |
| 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 tree issubstantially as illustrated and described and which is characterized by producing yellow fleshed, semi-cling fruit having a skin of bright red to yellow coloration tenacious to the flesh ripening for harvest about June 8 to June 10 when ungirdled andresponding well to girdling by advancing the harvest date of the fruit several days with only a very minor percentage of splitting of the stones of the fruit. |
| Description: |
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of peach tree, denominated "June Sun", which responds very well to girdling and produces yellow fleshed, semi-cling fruit with skin tenacious to the flesh and of high red color ready forharvest about the fifth to the eighth of June in the San Joaquin Valley of California.
The commercial value of tree fruit is frequently directly related to how early in the season the fruit can be delivered to market. Thus, the earlier ripening varieties of tree fruit often are of the greatest commercial value. The "Spring Crest"peach tree is an example of a variety which is commercially successful, in part, because of its early ripening fruit.
However, early ripening varieties of peach tree commonly have characteristics which detract from their commercial appeal. The fruit of such varieties is normally of small size and therefore not as appealing. It has been known that by girdlingsuch trees, not only can the date of ripening of the fruit be advanced up to a week, but the size of the fruit is also enhanced. Conversely, such girdling commonly causes a substantial increase in the percentage of splitting of the stones or pits of thefruit.
The variety of the present invention is distinct from such known varieties of peach tree in that it ripens early and responds well to girdling. Girdling advances the date of harvest to before that of the "Gem Free" peach tree, while if ungirdledthe variety will be ready for harvest after the "Gem Free" peach tree. Furthermore, girdling of the instant variety does not seem to affect the holding quality or color of the fruit and splitting of the stones of the fruit, while virtually nonexistentif the trees are not girdled, is very minor where the trees are girdled.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The instant new variety of peach tree was discovered by me in 1978 and is a newly found seedling of the "June Lady" peach tree. Seeds of the June Lady peach tree were planted in a plot in the nursery of H. P. Metzler & Sons at 5286 South Del ReyAvenue, Del Rey, Calif. 93616 in 1975. The fruit of the present variety was observed in 1978 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 several seedlings with scions from the newly discovered seedling. In the winter of 1979 the grafted seedlings were planted in a test nurseryof H. P. Metzler & Sons at Del Rey, Calif. The seedlings of the new variety were observed in the nursery over several growing seasons and the tree and fruit characteristics resulting from such asexual reproduction proved to be identical to those of theoriginal seedling of the new variety.
SUMMARY OF THE NEW VARIETY
The instant variety of peach tree is characterized by producing yellow fleshed, semi-cling fruit having a skin of bright red to yellow coloration tenacious to the flesh ready for harvest about June 8 to June 10 in the San Joaquin Valley ofCalifornia when ungirdled and responding quite well to girdling by advancing the harvest date of the fruit several days without affecting the holding quality or color of the fruit and with only a very minor percentage of splitting of the stones thereof.
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 stem, a second positioned to show the apex, a third positioned to show the side having the suture and a fourth sliced along itslongitudinal axis with the pit left in place. A representative twig is also shown in the photograph with characteristic leaves.
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.
