USPP12905P2 - Nectarine tree named ‘Mike's Red’ - Google Patents

Abstract

A new and distinct variety of nectarine tree is characterized by producing a semi clingstone fruit with a gold red blush coloration and is ripe for commercial harvesting and shipment August 15-20 in the San Joaquin Valley of Central California. The new variety is closely similar to the ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363) from which it is a sport but from which it is distinguishable in that the fruit ripens about three to five days prior to the ‘August Red’ nectarine tree and the fruit is somewhat larger in size than that of the ‘August Red’ nectarine tree. The fruit of the in instant variety has a very good flavor compared to the ‘August Red’ nectarine tree.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree which will hereinafter be denominated varietally as the ‘Mike's Red’ nectarine tree and more particularly as a nectarine tree which produces semi clingstone fruit which can mature for commercial harvest approximately August 15-20, three to five days before ‘August Red,’ in the San Joaquin Valley of Central California. The fruit is a fresh market nectarine with very good red blush in coloration and larger fruit than the parent ‘August Red.’

In the development of new commercial varieties of fruit trees a premium (good to excellent character) is frequently placed on those varieties that possess good size, good skin color, good flavor, as well as good holding or storage capabilities, as well as niche or specific time unique for this fruit. Thus in many instances some of the later varieties may lack one of these characteristics and would not be acceptable in the fresh market. The nectarine tree of this subject invention appear to be a promising candidate since it does not appear to have any of the above described flaws.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of nectarine tree was discovered by the inventor in his orchard of ‘August Red’ nectarine trees (U.S. Plant Pat. No. 6,363) which is located near Cutler, Calif. in the San Joaquin Valley of Central California. The inventor discovered the new variety as a sport of the ‘August Red’ nectarine tree in 1996. The new variety was first asexually reproduced by the inventor's representative in 1998-1999 by bud grafting trees in a nursery in Fowler, Calif. on Nemared rootstock using buds from mature wood. The asexually reproduced trees first bore fruit of the new variety in August 2000. The inventor carefully compared the asexually reproduced trees with the parent including the fruit thereof and has confirmed that the parent's progeny are in all respects identical.

SUMMARY OF THE NEW VARIETY

The ‘Mike's Red’ nectarine is characterized by producing a semi clingstone fruit which has a good red blush coloration and is ripe for commercial harvesting and shipment approximately August 15-20 in the San Joaquin Valley of Central California. The new variety is closely similar to the ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363) but from which it is distinguishable in that it ripens three to five days earlier than the fruit of the ‘August Red’ nectarine tree and the fruit is somewhat larger in size than that of the ‘August Red’ nectarine tree. The fruit of the new variety produces a very good flavor.

The present nectarine tree is raised in the San Joaquin Valley of Central California where it is dormant during the winter, so winter hardiness is not a problem. Since the invention is normally irrigated during the growing season, drought is not a factor. There does not appear to be any evidence of heat susceptibility for the fruit as well as the foliage. Although the new variety of nectarine trees possesses the above described characteristics as a result of the growing conditions prevailing near Cutler, Calif. in the Central San Joaquin Valley, it is to be understood that variations of the usual magnitude and characteristics may occur as a result of changes in growing conditions, irrigation, fertilization, pruning, pest control, climatic variations and the like are to be expected.

Claims (1)

Having thus described and illustrated my new variety of nectarine tree which I claim as new and desire to be secured by plant letters patent is:

1. A new and distinct variety of nectarine tree substantially as illustrated and described which is remotely similar to ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363) from which it is a sport by producing an earlier maturing fruit with good size and good exterior coloration and eating quality which are mature for commercial harvesting and shipment approximately August 15-20 or about three to five days earlier than the fruit of ‘August Red’.
