Nectarine tree, "Kam Red"

Abstract

A new and distinct nectarine tree denominated varietally as "Kam Red" and generally resembling the Flamekist nectarine tree (unpatented) but bearing a freestone fruit which is mature for harvesting and shipment approximately five to six days earlier than that of the Flamekist nectarine tree in the San Joaquin Valley of Central California.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree, denominated varietally as "Kam Red", and which is generally similar in its overall physical appearance to the Red Jim variety of nectarine tree (U.S. Plant Pat. No. 4,518), and the Flamekist nectarine tree (Unpatented), of which it is a newly found bud sport, but from which it is distinguished as to novelty by bearing a more deeply colored fruit which ripens for harvesting approximately August 7 through August 14 at Reedley, Calif., the subject variety ripening for harvest approximately five to six days earlier than the Flamekist variety of nectarine tree and approximately ten to eighteen days earlier than the Red Jim nectarine tree at the same geographical location.

The Flamekist nectarine tree (unpatented), which was originated by the Crops Research Division; Agricultural Research Service of the U.S. Department of Agriculture, is well known as a moderately vigorous producer of large, ovate, firm fleshed and clingstone fruit which are ripe for harvesting in Reedley, Calif. during the third week of August. Furthermore, the Flamekist nectarine tree has long been known for its attractive skin coloration and excellent eating qualities.

It has long been recognized that it would be desirable to have a nectarine tree which somewhat resembled the Flamekist nectarine tree but which bears fruit that ripen for harvesting earlier in the season whereby the commercial demand for such a nectarine can be effectively satisfied over a greater period of time.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of nectarine tree hereof was a chance bud sport discovered by the inventors in 1984 within the cultivated area of the Minami Ranch which is located at 10310 South Buttonwillow in Reedley, Calif. The bud sport, which was discovered by the applicants in a planting of Flamekist nectarine trees, was noted at that time to have desirable characteristics. Bud wood from this sport was procured by the applicants and grafted into test trees located on the same ranch. This first asexual propagation, which took place in 1986, resulted in progeny being produced that were found to possess the same distinctive characteristics as the original bud sport.

SUMMARY OF THE NEW VARIETY

The Kam Red variety of nectarine tree is characterized by many of the desirable characteristics of the Flamekist variety of nectarine tree (unpatented) but has the important distinction of bearing fruit that is more deeply colored than that of the Flamekist variety and which is ripe for harvesting and shipment approximately August 7 through August 14; this date of harvesting being approximately five to six days earlier than the Flamekist nectarine tree at the same geographical location. Further the fruit of the subject invention is freestone, in contrast to its parent, which is clingstone. Moreover, the fruit produced by the variety "Kam Red" possesses a flesh which is lightly yellow colored with some red coloration in the vicinity of the pit cavity at picking time.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of five mature fruit of the subject variety, one of which has been divided in the suture plane to illustrate the flesh and pit characteristics; together with a twig bearing representative leaves which display the dorsal and ventral coloration thereof.
