Apricot tree named `StB14/22`
Abstract
A new and distinct apricot variety is described. The variety
results from selection among a population of seedlings derived from
controlled crossing of the apricot varieties known as `Late
Moorpark` (not patented) and `Bhart` (not patented), marketed as
Orangered.TM.. The new variety is distinguished from others by the
deep red over color of the mature fruit accompanied by mid-orange
colored firm flesh with high soluble solids content. Fruit of
`StB14/22` matures in mid-February in Otago, New Zealand.

Claims
The invention claimed is:
1. A new and distinct apricot plant substantially as herein
illustrated and described.
Description
Genus and species of plant claimed: Prunus armeniaca.
Variety denomination: `StB14/22`.
BACKGROUND TO THE INVENTION
Seedlings obtained from the deliberate crossing of the apricot
varieties `Bhart` (not patented) (female parent), marketed as
Orangered.TM., and `Late Moorpark` (not patented) (male parent), in
September 2001, were planted out at Clyde, Otago, New Zealand,
where the cross was also conducted. In February 2006, `StB14/22`
was identified as having potential as a new variety. Later in 2006,
`StB14/22` was asexually propagated from bud wood taken at Clyde
and budded at Hawkes Bay, New Zealand, onto `Golden Queen` (not
patented) peach seedlings, the standard apricot rootstock in New
Zealand. The resulting trees were planted out at Clyde in the
Southern Hemisphere winter of 2007, and were subsequently found to
be true to type demonstrating that the characteristics of the new
variety, `StB14/22`, are stable and transmitted without change
through succeeding generations.
SUMMARY OF THE INVENTION
`StB14/22` is characterised by medium sized fruit (70-100 g) with a
deep red overcolor, mid orange colored firm flesh and high soluble
solids content which mature in mid-late February in Otago, New
Zealand. `StB14/22` is distinguished from a number of varieties by
the following characteristics:
`StB14/22` has firmer flesh, higher acidity, and a slightly later
harvest date when compared to `F168` (U.S. Plant Pat. No. 16,071)
(also known as `Larclyd`, marketed as Genevieve) grown at
Clyde.
StB14/22 is harvested more than a month later than Bhart. At Clyde,
StB14/22 is harvested in mid-February and `Bhart` in early
January.
Fruit of `StB14/22` is elliptical in shape where as `F194` (U.S.
Plant Pat. No. 16,119) (also known as `Southern Cross`) is round,
as is that of `Late Moorpark`.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical specimens of the plant,
fruit, and leaves of the new variety as depicted in colors as
nearly true as is reasonably possible to make the same in color
illustrations of this character.

old, in winter.
FIG. 2 shows a `StB14/22` fruit on the tree.

leaves.
DETAILED DESCRIPTION
The following is a brief description of the new variety with color
terminology in accordance with The Royal Horticultural Society
Colour Charts (R.H.S.C.C) 2001 edition. The specimens described
were grown at Clyde, New Zealand. The observations were made over
the 2012-2013 seasons on 7 year old mature trees. Tree: Average of
approximately 3.5 m tall with a spread of approximately 2.3 m,
medium vigour with an upright to spreading habit `StB14/22` scions
are compatible on peach seedlings (`Golden Queen`) root stocks.
Tree health is considered to be good under Central Otago conditions
in New Zealand with a medium level of precocity compared to
commercially grown varieties under similar conditions. Trunk:
Average circumference of a mature trunk, approximately 30 cm from
the graft union was 365 mm. Trunk color was observed to be near
brown N200B, with a reticulate bark texture, and a medium density
distribution of near greyed orange 165D oblanceolate lenticels
which averaged approximately 3.5 mm long and 2.0 mm wide.
One-year-old shoot: Observed in winter were observed to be near
greyed orange 166A in color with near greyed-orange 166A, medium
sized bud supports which averaged approximately 4.0 mm in diameter
and 4.4 mm in height. Dormant buds were observed to be near greyed
orange 166A in color and approximately 3.4 mm long and 1.9 mm wide.
Leaves: The leaves examined were fully expanded and harvested from
the central third of growing shoots in summer. The overall shape of
the leaves was observed to be broad ovate with an acute acuminate
tip approximately 15.7 mm long, a truncate base and serrate margins
with a weak undulation. Leaves are arranged alternatively and
averaged 96.6 mm long and 81.7 mm wide. The color of the upperside
was near green 137A and the underside near green 137C. The leaf had
a slight gloss and the profile in cross section was moderately
concave. The venation pattern of the leaf was reticulate and the
color of the venation near yellow green 145C. Petiole: The average
petiole length of fully expanded leaves was 41.5 mm and 1.7 mm in
diameter. The upperside of the petioles had a medium anthocyanin
coloration of near greyed purple 187C. Petioles were observed to
have between two and three small nectaries close to the leaf base
which had an average diameter of 0.9 mm. Flowers: Observations were
made at full bloom unless otherwise stated. Bud burst was recorded
in early September (approximately 6.sup.th September), with full
bloom occurring mid September (approximately 12.sup.th September).
Flowers were medium sized, the average diameter of an open flower
with petals pressed flat was 31 mm and distributed approximately
equally on spurs and one-year-old shoots, with a medium strength
fragrance. Corolla: Five petals per flower, with an average length
of 11 mm (excluding claw) and an average width of 13 mm and a 0.5
mm claw. The petal shape (excluding claw) was approximately
circular with a smooth but sinuate margin. Petals were near white,
N155D, at full bloom with near red-purple 62B veins. Stamens: An
average of around 24 per flower. Filaments were translucent white
in color with near yellow-orange 17D anthers and near greyed-orange
163B pollen. Anthers were on average 1.2 mm long and 1.0 mm wide.
Carpel: Pistals were on average approximately 17 mm and colored
near yellow-green 154D. The stigma sat above the anthers. Pedicel:
Average approximately 5.2 mm long and 6.8 mm wide. Calyx: Five
sepals per flower, average length of 7.0 mm and width 4.5 mm with a
right angle apex and a smooth margin. Colored near red purple 59B.
Fruit: Fruit at horticultural maturity were medium sized and
observed to be on average 70-100 g, with an average height of 48.9
mm, average lateral width of 49.1 mm, and average ventral width of
44.9 mm. `StB14/22` fruit were slightly asymmetric and were
circular in lateral view and ovate in ventral view with a slightly
sunken suture and a truncate apex. The stalk cavity was shallow,
approximately 2.9 mm deep. The skin surface was smooth with minimal
pubescence, medium gloss, a background color of near orange 25B,
and approximately 25-40% overcolor colored near red 46B made up of
a combination of a solid flush and isolated spots. The flesh color
was near orange 25A and near orange 25B in the stone cavity with no
whiteness around the stone. The flesh texture was fine and firm, an
average of approximately 2.9 kgf, with a very weak adherence to the
stone and average soluble solids of approximately 18.8%. Stone:
Observations were made on dry stones unless otherwise stated.
Stones were elliptic in shape, lateral view, with an acute apex,
and obtuse base. Stones were on average approximately 3.7 g, 28.9
mm long, with an average lateral width of 22.4 mm, and an average
ventral width of 13.3 mm. The stone was colored near grey brown
N199D. Harvest timing: Fruit begin ripening late in the season,
approximately 17.sup.th-19.sup.th February in Clyde, New Zealand.
Use: Fresh eating. Keeping quality: Has been shown to store very
well for at least four weeks at 0.degree. C. Pest and disease:
`StB14/22` has no known particular tolerances or susceptibilities
to pests and diseases associated with apricot trees.
