Abstract

A new and distinct variety of cherry tree denominated varietally as ‘Kootenay’ is described, and which is characterized as to novelty by a date of maturity for commercial harvesting and shipment which is approximately 9 to about 18 days later than the fruit produced by the “Lapins” cherry tree (unpatented) when grown under the ecological conditions prevailing near Creston, British Columbia, Canada.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel and distinct variety of cherry tree, “Prunus Avium L” and which has been denominated varietally as ‘Kootenay’.

ORIGIN

The present variety of cherry tree was discovered as a whole tree mutation growing within the cultivated region of my orchard that was planted in 1992, and which is located near Creston, British Columbia, Canada. The whole tree mutation was discovered within a block of “Lapins” cherry trees (unpatented), and which were then growing on Mazzard rootstock (also unpatented). At the time of its discovery, which occurred on Aug. 4, 1996, the tree was noted as producing fruit which were mature for harvesting and shipment consistently later than the adjacent “Lapins” cherry trees then growing in the same block.

ASEXUAL REPRODUCTION

Asexual reproduction of this new and distinct variety of cherry tree was accomplished in the same orchard located near Creston, British Columbia by removing bud wood from the original whole tree mutation and thereafter budding it into test trees then growing on Mazzard rootstock (unpatented) that were then growing in the same orchard. This second generation asexual propagation took place during the 1997 growing season. Since that time, the inventor has continually observed these second generation asexually reproduced trees, and have observed and considered the characteristics of these trees, and the fruit produced thereby, and it would appear from his observations, that the characteristics of the originally discovered mutated tree, and its fruit, were established and appear to be transmitted through the succeeding asexual propagations.

SUMMARY OF THE VARIETY

‘Kootenay’ is a new and distinct variety of cherry tree which produces a sweet cherry which is somewhat similar in its characteristics to the fruit produced by the “Lapins” cherry tree (unpatented) both in terms of its wood, leaf bloom and other fruit morphology. However, ‘Kootenay’ is distinguishable from the “Lapins” cherry tree, and characterized principally as to novelty by producing fruit which has a date of maturity for harvesting and shipment between August 14^th and August 20^th under the ecological conditions prevailing near the orchard of origin. This date of harvesting is at least nine days later than the date of harvesting of the “Lapins” cherry tree at the same geographical location. In addition to the foregoing, the present variety is distinct therefrom by producing fruit which are much firmer than the fruit produced by the “Lapins” cherry tree when grown under the same ecological conditions prevailing near Creston, British Columbia.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings which are provided are color photographs of the present cherry tree variety.

FIG. 1 depicts a fruiting branch of the ‘Kootenay’ cherry tree.

FIG. 2 is a second view of the fruit produced by the ‘Kootenay’ cherry tree following the harvesting of same.

FIG. 3 shows a relative comparison of the fruit produced by the ‘Kootenay’ cherry tree (left) as compared to the fruit produced by the “Lapins” cherry tree (right).

The external coloration of the fruit as shown in these photographs is sufficiently matured for harvesting and shipment. The colors as seen in these photographs are as nearly true as is reasonably possible in a color representation of this type. Due to chemical development, processing and printing, the leaves and fruit depicted in these photographs may or may not be accurate when compared with the actual specimen. For this reason, future color references should be made to the referenced color plates (Royal Horticulture Society), and the descriptions provided for hereinafter.
