Nectarine tree, ‘GBN-ONE’
A new distinct variety of nectarine tree is disclosed, and which produces an attractively colored clingstone nectarine which is mature for harvesting and shipment approximately August 20-24th under the ecological conditions prevailing in the San Joaquin Valley of central California.
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica var. nucipersica, and which will hereinafter be denominated varietally as ‘GBN-ONE,’ and more particularly to a nectarine tree which produces fruit which are mature for harvesting and shipment during the third week of August in the central San Joaquin valley of California.
DISCOVERY AND ASEXUAL REPRODUCTIONThe present variety of nectarine tree was discovered as a bud sport of the ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363) during the 2000 growing season. The new variety was discovered in a cultivated nectarine orchard which is located along Avenue 400 and Road 120 near the town of Orosi, Calif. The inventor upon identifying the promising new variety asexually reproduced the newly discovered variety during the dormant season between the years of 2000 and 2001 by budding the newly discovered variety of nectarine tree onto ‘Nemaguard’ (unpatented) rootstock at an orchard which is located along Avenue 408 and Road 136 near Cutler, Calif. These asexually reproduced trees bore their first fruit during August, 2002. The inventor has carefully compared the asexually reproduced trees with that of the original bud sport including the fruit produced by the respective trees. Still further, it was confirmed during the 2003 growing season that the trees and fruit produced by these asexual reproductions are identical in all respects to the original bud sport.
SUMMARY OF THE VARIETYThe ‘GBN-ONE’ nectarine tree is characterized principally as to novelty by producing a clingstone fruit having an exceptionally desirable coloration, and which matures during the third week of August under the climatic conditions prevailing in the central San Joaquin Valley. This date of harvesting is about 3 to 5 days after the ‘August Fire’ nectarine tree (U.S. Plant Pat. No. 11,477) which also produces a highly colored fruit, and is further closely similar in its harvesting date to the ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363), from which it was derived from a bud sport. However, the present variety is clearly distinguishable from the ‘August Red’ nectarine tree (U.S. Plant Pat. No. 6,363) by producing a more highly colored nectarine fruit. The present variety ‘GBN-ONE’ is also noted for its good flavor, noteworthy storage characteristics and further that the fruit holds well on the tree prior to harvest. The asexually reproduced trees appear to bear consistently from year to year.
The accompanying drawing is a color photograph showing a characteristic twig bearing typical leaves; several leaves showing both the dorsal and ventral coloration thereof, and several mature fruit showing their external coloration when sufficiently matured for harvesting and shipment. Additionally, a single stone is shown along with two fruit of the subject variety which have been dissected and which illustrate the flesh and stone characteristics of the newly discovered variety.
Referring more specifically to the horticultural details of this new and distinct variety of nectarine tree, the following characteristics have been observed under the ecological conditions prevailing at the orchard of origin which is located near Orosi, Calif. in the San Joaquin Valley of central California. All major color code designations are by reference to the Dictionary of Color by Maerz and Paul, 1st Ed. 1930. Common color names are also occasionally employed.
