Abstract

A new and distinct variety of nectarine tree which has a low winter chilling requirement of approximately 250 chill units (cu). The tree is of large size, is highly vigorous spreading growth habit and has nonshowy pink flowers. Glands are small and reniform in shape and isolated to the basal portions of leaves. This tree, which has been denominated `UFQueen` is a regular bearer of heavy crops of early maturing, large for early ripening season, with very firm non-melting flesh, clingstone fruit having yellow flesh color. Fruit is uniform, attractive, substantially symmetrical shape, and has an attractive normally 90 to 100% solid red skin. The fruit ripens substantially with that of `Sunraycer` in early to mid-May at Gainesville, Fla.

Description

BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of nectarine (Prunus persica (L.) Batsch) tree which is named `UFQueen` and, more particularly to a nectarine tree which produces highly colored, good eating quality, clingstone, non-melting flesh fruit which are mature for fresh market in early to mid-May at Gainesville and which are produced on a tree adapted to a mild winter climate. Asexual propagation was performed at Gainesville, Fla. where the selection was made and tested. Contrast is made to `Sunraycer` (unpatented) nectarine, a standard variety, for reliable description. This new variety is a promising candidate for commercial success in that it retains fruit firmness at the full flavor, tree ripe stage for 10 days on the tree.
ORGIN OF THE VARIETY
This nectarine tree (genotype) originated in the tree fruit breeding program at the University of Florida, located at Gainesville, Fla. `UFQueen` originated as an open-pollination of selection Fla.86-28c (unpatented), a non-melting flesh peach. `UFQueen` nectarine was selected from about 80 siblings in 1994, and exhibited yellow, non-melting, clingstone flesh, and thus was designated Fla. 94-28cn. It was propagated asexually as a uniform variety and determined at Gainesville to have unique tree and fruit characteristics making it worthy for commercial production. `UFQueen` has transmitted uniformity in fruit and tree traits through two standard asexual propagations by budding on `Flordaguard` (unpatented) seedling rootstock. There are no known effects of `Flordaguard` rootstock on the scion variety.
SUMMARY OF THE VARIETY
The new and distinct variety of nectarine tree bears yellow, non-melting flesh fruit, and has a low-chilling dormancy requirement. `UFQueen` blooms with `Sunraycer` nectarine at Gainesville and is the only nectarine variety known to me in the USA with such a low-chilling requirement that bears red skin over yellow and non-melting flesh, with early-ripening fruit. The estimated chilling requirement is 250 chill units. When grown in subtropical climates to take maximum advantage of its early bloom (low-chilling) `UFQueen` will be among the first non-melting flesh nectarine varieties to ripen in the USA.
The present invention resulting in `UFQueen` nectarine tree is characterized by non-melting flesh fruit of excellent flavor and eating quality on a tree adapted to mild winters. The trees are vigorous, productive and regular bearing. Trees attain in two years a height of three meters and a spread of two meters at Gainesville. Terminal growth of up to a meter is common on mature five-year-old trees. The first fruit ripen in early to mid-May at Gainesville or in about 95 days from full bloom. The fruit are uniformly medium large for an early ripening nectarine. Ripe fruit have 90 to 100 percentage of solid red skin color with no red pigment throughout the flesh or at the pit. The flower anthers are light red to yellow, a common characteristic of many standard nectarine and peach varieties.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying color photograph shows a typical specimen of the fruit, leaf, and stem of the new variety as nearly true as it is reasonably possible to make in a color illustration of this type. The photograph shows an attractive shape and exterior coloration of four specimens of fruit above a ruler in side view, stem end view, a blossom end view, and side view showing the suture. It also depicts new wood, internode length, leaves, glands, leaf stems, and axillary buds.
BOTANICAL DESCRIPTION OF VARIETY
The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by `UFQueen` is high, due to its attractive red skin, early ripening of good flavor, and exceptional firmness due to its non-melting flesh. The present botanical description is that of the variety grown under the ecological conditions prevailing near Gainesville, Fla. Colors are described from "The Pantone Book of Color" published by H. N. Abrams, Inc., N.Y. 1990.
