Nectarine tree 'Burnectwentythree'

Abstract

A new and distinct variety of nectarine tree (Prunus persica sub species nuciperisica), denominated varietally as ‘Burnectwentythree’, and which produces an attractively colored white-fleshed, non-melting, sub-acid, saucer-shaped, clingstone nectarine, which is mature for harvesting and shipment approximately June 12 to June 20 under ecological conditions prevailing in the San Joaquin Valley of central California.

Description

BACKGROUND OF THE NEW VARIETY[0001]The present invention relates to a new, novel and distinct variety of nectarine tree, Prunus persica (subspecies nucipersica), which has been denominated varietally as ‘Burnectwentythree’.[0002]The present variety of nectarine 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 available 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.[0003]The seedling ‘Burnectwentythree’ 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 made in February of 2000, of the yellow-flesh...

AI Technical Summary

Benefits of technology

[0005]‘Burnectwentythree’ is a new and distinct variety of nectarine tree, which is also a regular and productive bearer of relatively firm, sub-acidic white fleshed, non-melting, clingstone, saucer-shaped fruit which have a good flavor and eating quality. The tree of the present variety displays a medium low chilling requirement of approximately 550 hours. Still further, the present tree also produces relatively uniformly sized fruit throughout the tree. Additionally, the fruit produced by the present tree has a high degree of red skin coloration, a firm flesh and appears to have good handling and shipping qualities. The ‘Burnectwentythree’ Nectarine tree bears fruit which are ripe for commercial harvesting and shipment on approximately June 12 to June 20 under the ecological conditions prevailing in the San Joaquin Valley of central California. In relative comparison to the peach tree ‘Burpeachone’, which is the seed parent, the ‘Burnectwentythree’ Nectarine exhibits white flesh whereas the ‘Burpeachone’ exhibits yellow flesh. Additionally the present variety ripens approximately 2 weeks or more later than the peach tree ‘Burpeachone’. In relative comparison to the nectarine tree ‘Spring Bright’ (U.S. Plant Pat. No. 7,507), which is the most similar variety known to the inventors at this time, the present new variety produces fruit which is white-fleshed and saucer-shaped whereas the ‘Spring Bright’ is yellow fleshed and globose shaped.

Problems solved by technology

It is common in saucer-shaped fruit to have a poorly formed endocarp due, at least in part, to the limited space which is available with the mesocarp.
