| Abstract: |
A new and distinct variety of nectarine tree which is somewhat similar to the September Grand Nectarine Tree (U.S. Plant Pat. No. 1,755) from which it was derived as a chance sport but which is distinguished therefrom and characterized as to novelty by producing fruit which is mature for commercial harvesting approximately September 3 through September 19 at Clovis, Calif. and which has excellent shipping and storage characteristics. |
| Claim: |
Having thus described and illustrated my new variety of nectarine tree, what I claim as new and desire to secure by Plant Letters Patent is:
1. A new and distinct variety of nectarine treesubstantially as illustrated and described which is characterized as to novelty by bearing a clingstone fruit having a yellow colored flesh, a skin color which is 80% to 90% red and by its general resemblance to the September Grand Nectarine Tree, U.S. Plant Pat. No. 1,755, from which it was derived as a chance sport, but from which it is distinguished therefrom by its bearing fruit which matures for harvesting approximately September 3 through September 19, later than the September Grand NectarineTree and by having excellent shipping and storage characteristics. |
| Description: |
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of nectarine tree denominated varietally as the "P-R Red", and more particularly to a Nectarine Tree which is generally similar in physical characteristics to the September GrandNectarine Tree (U.S. Plant Pat. No. 1,755), of which it is a newly found sport, but from which it is distinguished as to novelty by bearing fruit which is ripe for commercial harvesting approximately September 3 through September 19 at Clovis, Calif.,this date of harvest being approximately 5 to 7 days later than the September Grand Nectarine Tree which is generally ripe for commercial harvesting approximately the second week of September at Clovis, Calif.
The September Grand Nectarine Tree (U.S. Plant Pat. No. 1,755) is well known as a vigorous producer of large, firm flesh clingstone fruit which are ripe for commercial harvesting approximately the second week in September in the San JoaquinValley of Central California. Furthermore, the fruit of the September Grand has long been known for its excellent eating quality, long shelf life and distinct aroma.
It has long been recognized that it would be desirable to have a nectarine tree which somewhat resembles the September Grand Nectarine Tree but which bears fruit which ripens for harvest later in the season whereby the commercial demand for sucha late season nectarine can be supplied over a prolonged period of time.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The new and distinct variety of nectarine tree hereof was discovered as a chance sport on the applicant's property located at the corner of Bullard and Armstrong Avenues in Clovis, Calif. in September, 1972. The sport, which was found in acommercial planting of September Grand nectarines by the inventor, was noted at that time to have desirable characteristics. Bud wood from the sport was thereafter grafted into test trees by Mr. Glen Lewis, an employee of the applicant, on the sameproperty located at the corner of Bullard and Armstrong Avenues in Clovis, Calif. This first asexual propagation which took place in January, 1973 has been continually observed by the applicant and it has been subsequently determined that this firstgrafting resulted in progeny being produced that were found to possess the same distinctive characteristics as the original sport.
SUMMARY OF THE NEW VARIETY
The P-R Red variety of nectarine tree is characterized by many of the desirable characteristics of the September Grand Nectarine Tree (U.S. Plant Pat. No. 1,755), but has the important distinction of bearing fruit that is different incoloration than that produced by the September Grand Nectarine Tree, and which is further ripe for commercial harvesting approximately September 3 through September 19; the September Grand Nectarine being usually ripe for commercial harvesting in thesecond week of September. The fruit of the new variety is clingstone by nature and has a flesh coloration that is light yellow with some reddish-pink coloration in the pit cavity and areas closely adjacent thereto.
BRIEF DESCRIPTION OF THEDRAWING
The accompanying drawing is a color photograph of six mature fruit of the subject variety, two of the mature fruit have been divided in the suture plane to show the flesh and pit characteristics, together with representative leaves which displaythe dorsal and ventral coloration thereof, and two pits, all of the subject variety.
DETAILED DESCRIPTION
Referring more particularly to the pomological details of this new and distinct variety of nectarine tree, the following has been observed under the ecological conditions prevailing at the applicant's commercial orchard which is located at thecorner of Bullard and Armstrong Avenues in Clovis, Calif. All major color code identifications are by reference to "The Dictionary of Color" by Maerz and Paul, Second Edition, and in the alternative, the "Inter-Society Color Council, National Bureau ofStandards." Common color names are also employed occasionally.
