Definitions
- the present invention relates to a new, novel and distinct variety of peach tree, Prunus persica, which has been denominated varietally as ‘Burpeachfifteen’.
- the present variety of peach tree resulted from an on-going program of fruit and nut tree breeding.
- the purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties and rootstocks by creating and releasing promising selections of prunus, malus and regia species.
- To this end we make both controlled and hybrid cross pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected.
- the seedling ‘Burpeachfifteen’ was originated by us from a population of seedlings grown in our experimental orchards located near Fowler, Calif.
- the seedlings, grown on their own roots, were the result of a controlled cross of the yellow-fleshed ‘B2.026’ peach tree (unpatented) which was used as the seed parent and the white-fleshed, nectarine tree, ‘B17.025’, (unpatented) which was used as the pollen parent.
- One seedling, which is the present variety exhibited especially desirable characteristics, and was designated as ‘E24.018’. This seedling was marked for subsequent observation. After the 1999 season, the new present variety was selected for advanced evaluation and repropagation.
- ‘Burpeachfifteen’ is a new and distinct variety of peach tree, which is of large size, and which has vigorous growth, and which further is a regular and productive bearer of relatively large, firm, yellow fleshed, freestone fruit having good flavor and eating quality.
- the tree has a medium chilling requirement of approximately 600 hours.
- the new tree also produces relatively uniformly sized fruit throughout the tree.
- the fruit further has a high degree of red skin coloration, and a firm flesh.
- the fruit also appears to have good handling and shipping qualities.
- the ‘Burpeachfifteen’ peach tree bears fruit which are ripe for commercial harvesting and shipment on approximately August 28 to September 8 under the ecological conditions prevailing in the San Joaquin Valley of Central California.
- ‘Burpeachfifteen’ ripens at least about 12 or more days earlier.
- the accompanying drawing which is provided is a color photograph of the present variety. It depicts two whole mature fruit and one fruit is dissected substantially along the equatorial plane to expose the flesh and the pit thereof. Additionally a characteristic twig bearing typical leaves is shown. The external coloration of the fruit as shown is sufficiently matured for harvesting and shipment. The colors are as nearly true as is reasonably possible in a color representation of this type. Due to chemical development, processing and printing, the colors of the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual specimen. For this reason, future color references should be made to the color plates (Royal Horticultural Society) and the other descriptions provided for hereinafter.

Abstract
A new and distinct variety of peach tree (Prunus persica), and which is denominated varietally as ‘Burpeachfifteen’, and which further produces an attractively colored yellow-fleshed, freestone peach which is mature for harvesting and shipment approximately August 28 to September 8 under the ecological conditions prevailing in the San Joaquin Valley of Central California.
Description
The present invention relates to a new, novel and distinct variety of peach tree, Prunus persica, which has been denominated varietally as ‘Burpeachfifteen’.
The present variety of peach tree resulted from an on-going program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties and rootstocks by creating and releasing promising selections of prunus, malus and regia species. To this end we make both controlled and hybrid cross pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected.
The seedling ‘Burpeachfifteen’ was originated by us from a population of seedlings grown in our experimental orchards located near Fowler, Calif. The seedlings, grown on their own roots, were the result of a controlled cross of the yellow-fleshed ‘B2.026’ peach tree (unpatented) which was used as the seed parent and the white-fleshed, nectarine tree, ‘B17.025’, (unpatented) which was used as the pollen parent. One seedling, which is the present variety, exhibited especially desirable characteristics, and was designated as ‘E24.018’. This seedling was marked for subsequent observation. After the 1999 season, the new present variety was selected for advanced evaluation and repropagation.
Asexual reproduction of the new and distinct variety of peach tree was accomplished by budding to ‘Nemaguard’ Rootstock (un-patented) after the 1999 growing season. This was performed by us in our experimental orchard located near Fowler, Calif. Subsequent evaluations performed in latter years have shown those asexual reproductions run true to the original tree. All characteristics of the original tree and its fruit were established and appear to be transmitted through succeeding asexual propagations.
‘Burpeachfifteen’ is a new and distinct variety of peach tree, which is of large size, and which has vigorous growth, and which further is a regular and productive bearer of relatively large, firm, yellow fleshed, freestone fruit having good flavor and eating quality. The tree has a medium chilling requirement of approximately 600 hours. The new tree also produces relatively uniformly sized fruit throughout the tree. The fruit further has a high degree of red skin coloration, and a firm flesh. The fruit also appears to have good handling and shipping qualities. Still further, the ‘Burpeachfifteen’ peach tree bears fruit which are ripe for commercial harvesting and shipment on approximately August 28 to September 8 under the ecological conditions prevailing in the San Joaquin Valley of Central California. In comparison to the peach tree variety, ‘B2.026’ which is the seed parent, the present variety, ‘Burpeachfifteen’ ripens at least about 12 or more days earlier.
The accompanying drawing which is provided is a color photograph of the present variety. It depicts two whole mature fruit and one fruit is dissected substantially along the equatorial plane to expose the flesh and the pit thereof. Additionally a characteristic twig bearing typical leaves is shown. The external coloration of the fruit as shown is sufficiently matured for harvesting and shipment. The colors are as nearly true as is reasonably possible in a color representation of this type. Due to chemical development, processing and printing, the colors of the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual specimen. For this reason, future color references should be made to the color plates (Royal Horticultural Society) and the other descriptions provided for hereinafter.
Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following has been observed in the fourth fruiting season under the ecological conditions prevailing at our orchard which is located near the town of Fowler, county of Fresno, state of California. All major color code designations are by reference to The R.H.S. Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.
