ABSTRACT:
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new, novel and distinct variety of peach tree,
Prunus persica,
which has been denominated varietally as ‘Burpeachfifteen’.
ORIGIN
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
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.
SUMMARY OF THE VARIETY
‘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.
