Almond tree, ‘Supareil’

Abstract

A new and distinct variety of almond tree is described and which is somewhat similar to the ‘Nonpareil’ almond tree (non-patented), but which is distinguishable therefrom by producing a larger sized kernel of high quality and having a sweet flavor when compared to the with ‘Nonpareil’ almond tree (non-patented).

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of almond tree, Prunus dulcis, which will hereinafter be denominated varietally as ‘Supareil’ and more specifically to an almond tree which produces nuts for commercial harvesting, hulling, shelling and shipment during the first week of September, that is during September 3-7^th under the ecological conditions prevailing in the vicinity of Livingston, Calif. which is in the central part of the San Joaquin Valley of California. The present variety is also noteworthy for producing a soft-shelled almond with flavor characteristics which are considered to be excellent.

In the evaluation of almond tree varieties there is a number of criteria which are utilized to determine whether a new almond tree very will have commercial success. As a general matter, new trees and their crops are usually evaluated on the basis of their ripening date, flavor, texture, storage and shipping quality. With almonds, as with other produce, the date of ripening, the quality of the meat of the kernel, freedom from unusual numbers of doubles, as well as a soft shell makes a new variety commercially attractive, with a substantial likelihood of commercial success. It has long been known that almond tree varieties that produce a soft shell as opposed to hard shell nuts make the kernel removal much easier. Therefore, the ease of shelling, and the high quality of the kernel, plus a low percentage of doubles gives the present almond an excellent appeal to the distributor and consumer, alike. In relative comparison to other known varieties of almond trees, the present variety is clearly distinguishable. In this regard, and in relative comparison to the ‘Nonpareil’ almond tree (unpatented), and the ‘Carmel’ almond tree (U.S. Pat. No. 2,641), the present variety is clearly distinguishable by its date of harvesting (about 10 days later) and its excellent flavor. Further, in relative comparison to other nut varieties such as U.S. Plant Pat. No. 19,369, the present variety is distinguishable therefrom by its date of harvesting which is some two weeks later than the date of harvesting of aforementioned patented variety. Also, in relative comparison to the ‘Nonpareil’ variety, it has been observed that the present variety produces nut meat having a sweeter quality and a kernel which is slightly lighter in color, and larger in size.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of almond tree was discovered by the inventor in the late 1990's as a chance seedling of unknown parentage then growing within a cultivated region of his ‘Nonpareil’ (unpatented) almond orchard which is located near Chico, Calif. in the Northern Sacramento Valley. After several years of observation, the inventor determined that additional almond trees should be asexually propagated of this new variety to determine whether the observed characteristics of the newly discovered chance seedling would be true across multiple generations. In this regard, the inventor contracted to have a local nursery in Oakdale, Calif. asexually reproduce 500 trees onto Nemaguard (unpatented rootstock) for further planting and observation. These asexually reproduced trees were then planted in 2002 and have been continually observed by the inventor since that time. Further, during this analysis period, the nut characteristics as well as the kernel characteristics of the new variety were studied. Based upon all the collective observations made of this first group of asexually reproduced trees, it has been determined that these asexually reproduced trees appear to be identical to the original chance seedling which was found in the late 1990's in all respects. These first asexually reproduced trees were planted in an almond orchard then located in Livingston, Calif. This first group of asexually reproduced trees are now in their seventh leave. Further, it has been confirmed that the vigor of these trees is quite similar to the ‘Nonpareil’ almond trees growing in the same geographical vicinity.

SUMMARY OF THE VARIETY

The present variety of almond tree ‘Supareil’ is characterized as to novelty by producing a soft shell, well sealed almond which somewhat resembles the nut provided by the ‘Nonpareil’ almond tree (unpatented), but which is distinguishable therefrom, and characterized principally as to novelty by being mature for commercial harvesting, hulling, shelling and shipment during the first week of September, that is, September 3^rd-7^th under the ecological conditions prevailing near Livingston, Calif. The new variety of almond tree while somewhat similar in some of its characteristics to that of the ‘Nonpareil’ almond tree (unpatented), is distinguishable therefrom by producing a nut having a sweeter quality meat, a kernel which is slightly lighter in color, and larger in size, and which further is harvested about 10 days later than the unpatented ‘Nonpareil’ almond tree when grown at the same geographical location and under similar cultural conditions.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing which is provided is a color photograph of the new variety of almond tree. The color photograph depicts one branch of the present variety displaying its growth characteristics with almonds sufficiently matured for harvesting and shipment. Further, a twig bearing typical leaves showing the dorsal and ventral coloration thereof is also depicted. Additionally, several leaves showing the dorsal and ventral coloration are also displayed. In addition to the foregoing, six shelled almonds and their associated kernels are shown and which display the side view, overall shape, and suture characteristics thereof. The colors in this photograph are nearly as true as is reasonably possible in a color representation of this type. Due to chemical development, processing and printing, the leaves and nut crop depicted in these photographs mayor may not be accurate when compared to the actual specimen. For this reason, future color references should be made to the color plates as provided by The Royal Horticultural Society Colour Chart, 4th Edition.

    • Kernel surface texture.—Slightly ribbed.
    • Kernel pubescence.—Not evident.
    • Kernel color.—Grey-Orange, RHS N170 (B).
    • Number of doubles produced.—Of 79 specimens inspected, only 2 included doubles. This represented approximately a 2.5% rate for doubling.
    • Kernel flavor.—Generally — Considered sweet, and very good, and superior to that of the nut produced by the ‘Nonpareil’ almond tree (unpatented) which is growing in the same vicinity.
    • Storage quality.—Considered very good for the species in relative comparison to other varieties growing in the same geographical area.
    • Resistance to disease.—This variety appears to be resistant to anthracruss.
    • Pollination requirements.—This variety appears to need a pollinator. The nut variety ‘Aldrich’ (non-patented); and ‘Nonpareil’ (non-patented) appear to be good pollinators.
    • Average kernel weight.—About 1.47 grams/kernel. This characteristic does not distinguish the present variety from other known varieties because this characteristic is dependent, in part, on the cultural conditions under which the tree was grown.
    • Kernel size.—Generally speaking, and in relative comparison to the ‘Nonpareil’ almond tree (non-patented), the kernel produced by the present variety of almond tree is slightly larger in size than that produced by the ‘Nonpareil’ variety under similar ecological conditions. Further, the new variety of almond tree produces a kernel which is different in color and further has a flavor that is sweeter and distinctive from the crop produced by the ‘Nonpareil’ almond tree (non-patented), and which is growing in the same geographical area. Still further, in view of the low percentage of doubles that the present variety produces, this new variety of almond tree would appear to be quite distinctive and novel in relative comparison to the ‘Nonpareil’ almond tree (non-patented) which are growing in the same geographical area and which are mature for harvesting approximately 10 days earlier then this new variety.

Although the new variety of almond tree possess the described characteristics noted above, as a result of the growing conditions prevailing in the central part of the San Joaquin Valley of Central California, it is to be understood that characteristics of the usual magnitude incident to changes in growing condition, fertilization, pruning and pest control are to be expected.
