| Abstract: |
A new and distinct variety of persimmon tree which is somewhat remotely similar to the Fuyu persimmon tree, but from which it is distinguished by producing fruit which are mature for harvesting and shipment approximately 10 days to 2 weeks prior to the fruit produced by the Fuyu persimmon tree and which is of larger size. |
| Claim: |
Having thus described and illustrated my new variety of persimmon tree, what I claim as new and desire to be secured by Plant Letters Patent is:
1. A new and distinct variety of persimmon treesubstantially as illustrated and described which is somewhat remotely similar to the Fuyu persimmon tree, but from which it is distinguished by producing fruit which are mature for commercial harvesting and shipment approximately the first week ofOctober, or about 10 days to 2 weeks earlier than the fruit of the Fuyu persimmon tree, in the southern San Joaquin Valley of California and which has high coloration, large size and a very good flavor. |
| Description: |
Latin name of the genus and species of the plant claimed: Diospyros kaki L.
Variety denomination: Doc's Delight.
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of persimmon tree, which will hereinafter be denominated varietally as Doc's Delight, and, more particularly, to a persimmon tree which produces fruit, which are mature for commercialharvesting and shipment approximately the first week of October near Wasco in the southern San Joaquin Valley of California.
Commercial varieties of fruit trees may be distinguished, one from another, by a multiplicity of characteristics. Furthermore, there are many varieties of certain fruit trees while other types of fruit trees have only a few commerciallyrecognized varieties. For example, peach trees have a plethora of recognized commercial varieties while persimmon trees have very few. Thus, in the case of persimmon trees, there are considerably fewer varieties from which to choose, of course both inthe trees and the fruit therefrom. This makes new varieties of persimmon trees potentially of significantly more importance than is the case with peach trees. When this fact is coupled with all of the distinguishing characteristics, such as ripeningdate, size, coloration, flavor and the like, the commercial potential of such varieties may be significant.
The persimmon tree of the present invention appears to be a promising candidate in these regards, as will hereinafter be set forth in greater detail.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The persimmon tree of the present invention was discovered by the inventor in his persimmon orchard located near Wasco in the southern San Joaquin Valley of California. The inventor had planted about one thousand persimmon trees of the Fuyuvariety in the orchard in 1991. In October 1996, the inventor discovered four (4) persimmon trees of the new variety of the present invention in the orchard as a sport of the Fuyu persimmon tree. The persimmon trees of the instant variety were readilydistinguishable from the Fuyu persimmon trees in numerous respects including that they produced fruit which was ripe for commercial harvesting and shipment ten (10) to fourteen (14) days earlier that the fruit of the Fuyu persimmon trees.
In March 1997, at the inventor's direction, the persimmon tree of the instant invention was asexually reproduced by grafting bud wood of the new variety on to Diospyros kaki rootstock.
The inventor has closely watched the development of the asexually reproduced persimmon trees of the new variety since then and continues to observe the trees and has found them in all respects to be identical to the original trees of the subjectinvention.
SUMMARY OF THE INVENTION
The persimmon tree of the present invention is characterized by producing a large highly colored fruit, more specifically, of orange coloration which are ripe for commercial harvesting and shipment during the first week of October in the southernSan Joaquin Valley of California. The new variety most closely resembles the Fuyu persimmon tree, from which it is derived, but from which it is distinguished in a number of respects including that the fruit thereof ripens ten to fourteen days earlierthan the fruit of Fuyu persimmon tree and that the fruit of the instant variety is larger than that of the Fuyu persimmon tree.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph showing distinguishing characteristics of the new variety including fruit thereof with a first disposed in top plan view to display the stem end thereof with the calyx removed;
a second disposed bottom plan view to reveal the apex end thereof;
a third in side elevation; and
a fourth severed along its transverse axis and laid open to reveal the flesh thereof with an absence of seeds.
Also shown is a terminal section of a branch of the new variety displaying upper and lower surfaces of the leaves.
