Description
INCORPORATION OF ELECTRONIC SEQUENCE LISTING
The nucleic and amino acid sequences listed in the accompanying
sequence listing are shown using standard letter abbreviations for
nucleotide bases, and three letter code for amino acids, as defined
in 37 C.F.R. 1.822. The Sequence Listing is submitted as an ASCII

BACKGROUND
The present Invention relates to a new and distinct cultivar of
Corylus plant, botanically known as Corylus avellana, and
hereinafter referred to by the name `PollyO`.
The new Corylus resulted from a controlled cross of OSU
684.104.times.OSU 669.104 made in 2001 (FIG. 1); the progeny was
designated 01021. OSU 684.104 is from a cross of `Birk 5-39`
(unpatented) and `Mortarella` (unpatented). `Birk 5-39`, an OSU
selection growing in a small plot near Canby, Oreg., is from a
cross of OSU 14.084 (`Barcelona`.times.`Daviana`, both unpatented)
and `Negret` (unpatented). OSU 669.104 is a full sib of the
pollinizer `Zeta` (unpatented). OSU 669.104 carries a dominant
allele for a very high level of resistance to eastern filbert
blight (EFB) from the grower selection `Zimmerman` (unpatented).
Microsatellite marker analysis indicates that `Zimmerman` is from a
cross of `Barcelona` and the EFB-resistant pollinizer `Gasaway`
(Gokirmak et al., Characterization of European hazelnut (Corylus
avellana) cultivars using SSR markers. Genetic Resources and Crop
Evolution 56:147-172, 2009) (unpatented). The pedigree of `PollyO`
includes germplasm from Spain (`Barcelona`, `Casina`, and `Negret`,
all unpatented), Italy (`Mortarella` and `Montebello`, both
unpatented) and England (`Daviana`).
Hybrid seeds from the controlled cross were harvested in August
2001, stratified, and the resulting seedlings grown in a glasshouse
during the summer of 2002. 99 seedlings from this cross were
planted in the field in Corvallis, Oreg. in October 2002. The
designation OSU 1108.001 indicates the row and tree location of the
original seedling. Nuts were first observed on the original
seedling in September 2006. The nuts were harvested from the
original seedling tree and evaluated over four years
(2006-2009).
`PollyO` was propagated by tie-off layerage of the suckers in the
summer beginning in 2008. The rooted layers from the first
propagation (2008) were lined out in a nursery row the year after
layerage (2009), and used to plant a replicated yield trial the
following spring (2010). The first trial included four trees of
each variety. EFB-susceptible selections and check cultivars
`Barcelona`, `Clark` and `Sacajawea` (unpatented) (Mehlenbacher et
al., 2008. `Sacajawea` hazelnut. HortScience 43:255-257) were
planted on the same date in a trial adjacent to the first trial.
Fungicides were applied to the trial of susceptible genotypes to
reduce the incidence of EFB. The rooted layers from the second
propagation (2009) were lined out in a nursery row in 2010 and used
to plant a second trial in 2011. The second trial had seven blocks.
Both trials were planted as randomized complete block designs with
a single tree of each genotype in each block. EFB-resistant
cultivars `Jefferson` (unpatented) (Mehlenbacher et al., 2011.
`Jefferson` hazelnut. HortScience 46:662-664), `Yamhill`
(unpatented) (Mehlenbacher et al., 2009. `Yamhill` hazelnut.
HortScience 44:845-847) and `Gamma` (unpatented) (Mehlenbacher and
Smith. 2004. Hazelnut pollenizers `Gamma`, `Delta`, `Epsilon` and
`Zeta`. HortScience 39:1498-1499) served as checks in the first
trial, while `Jefferson` and `Yamhill` were the checks in the
second trial. Both trials included additional EFB-resistant
selections.
The new cultivar was asexually reproduced by tie-off layerage of
the suckers in the summer of 2008 and 2009 in Corvallis, Oreg. It
was moved with a tree spade to the layer beds in spring, 2010. Of
the 12 layers harvested in 2008, three were well-rooted, seven had
a modest number of roots, and two had no roots. The size (caliper)
was rated as medium. Layers harvested in 2009 showed improved
rooting. Further propagation by layerage of about 28 suckers per
year was performed in 2011-14, of which 39% were rated as
well-rooted, 26% with fair rooting, 26% with poor rooting and 9%
with no roots. In general, the layers rooted sufficiently well and
size (caliper) was medium to small. The unique features of this new
Corylus are stable and reproduced true-to-type in successive
generations of asexual reproduction.
SUMMARY
The following traits have been observed and are determined to be
the unique characteristics of `PollyO`. `PollyO` is well-suited to
the blanched kernel market for use in chocolate products and baked
goods. `PollyO` combines high nut yield, early nut maturity, small
round nuts and kernels, high kernel percentage, good kernel
blanching and excellent flavor. The tree is vigorous and has a
desirable growth habit. `PollyO` is resistant to bud mite
(primarily Phytoptus avellanae Nal.). DNA markers and field
exposure indicate that it is highly resistant to eastern filbert
blight (EFB) caused by Anisogramma anomala (Peck) E. Muller. The
resistance is conferred by a dominant allele from `Zimmerman`,
which microsatellite markers indicate is from a cross of
`Barcelona`.times.`Gasaway` (Gokirmak et al., Characterization of
European hazelnut (Corylus avellana) cultivars using SSR markers.
Genetic Resources and Crop Evolution 56:147-172, 2009). EFB is now
present throughout the Willamette Valley where 99% of the U.S.
hazelnut crop is grown. Pruning to remove cankers and fungicide
applications are currently used to manage the disease in orchards
of `Barcelona` and other susceptible cultivars. `PollyO` is
suitable for planting in areas with high disease pressure, as are
previous releases `Yamhill` (2008, unpatented), `Jefferson` (2009,
unpatented), `Dorris` (2012, US Plant Patent No. PP25,022)
(Mehlenbacher et al., 2013. `Dorris` hazelnut. HortScience
48:796-799), `Wepster` (2013, US Plant Patent No. PP27,141)
(Mehlenbacher et al., 2014. `Wepster` hazelnut. HortScience
49:346-349) and `McDonald` (2014, US Plant Patent No. PP28,200)
(Mehlenbacher et al., 2016. `McDonald` hazelnut. HortScience
51:757-760).
`PollyO` has incompatibility alleles S.sub.2 and S.sub.10. Both
alleles are expressed in the stigmas, but only S.sub.10 is
expressed in the pollen because of dominance. Female receptivity is
early, with `Wepster` and `McDonald`, while pollen is shed by
`PollyO` about ten days later than the other two. Pollen
germination is high and similar to `Wepster` and `McDonald`.
Recommended pollinizers include `Wepster` (S.sub.1 S.sub.2),
`McDonald` (S.sub.2 S.sub.15) and `York` (S.sub.2 S.sub.21) (US
Plant Patent No. PP24,972).
`PollyO` can serve as a companion for `Wepster` and `McDonald`, and
an alternative to `Yamhill`. Many growers find `Yamhill` trees
difficult to manage because of low vigor, and the kernels do not
blanch well. `Wepster` and `McDonald` are cross-compatible with
`PollyO` in all directions, giving growers additional options in
orchard design. All three cultivars (`Wepster`, `McDonald` and
`PollyO`) could be planted together with each serving as a
pollinizer for the others.
Comparisons in two replicated trials conducted in Corvallis, Oreg.,
plants of `PollyO` differed from plants of other cultivars and
selections of Corylus avellana known to the Inventors primarily in
nut yield, time of nut maturity, nut size, and kernel percentage
(ratio of kernel weight to nut weight). For example: Nut yield (kg
per tree): First trial: `PollyO` (29.39), `Jefferson` (24.26), and
`Yamhill` (26.47); second trial `PollyO` (23.46), `Jefferson`
(16.91), and `Yamhill` (21.69); Nut maturity: `PollyO` nuts mature
10-14 days earlier than `Barcelona`, a few days earlier than
`Yamhill`; Nut size (L.times.W.times.D): `PollyO` (19.5
mm.times.19.8 mm.times.17.2 mm), `McDonald` (18.4 mm.times.18.9
mm.times.17.9 mm), `Wepster` (18.3 mm.times.19 mm.times.16.6 mm)
(see also FIG. 14); and Kernel Percentage: `PollyO` (47.9%),
`McDonald` (51.5%), `Wepster` (43.9%), `Felix` (50.1%), `Dorris`
(43.0%), and `Barcelona` (43.0%).

susceptible, and plants of `Barcelona` are highly resistant.
Temperature Tolerance:
Plants of `PollyO` have been observed to tolerate temperatures from
-21 to 38.degree. C. in the field in Corvallis, Oreg.
Comparative Data:
Tree Size, Growth Habit, Yield, and Yield Efficiency.
Tree sizes in the two trials were estimated by measuring trunk
circumference 30 cm above the soil line, at the end of the 7.sup.th
growing season (December 2016 and November 2017, respectively).
Trunk cross-sectional area (TCA) was calculated from trunk
circumference. In the first trial, TCA of `PollyO` (OSU 1108.001)
was 118 cm.sup.2 or 126% of `Jefferson` and 91% of `Barcelona` in
the adjacent trial of EFB-susceptible selections. In the second
trial, TCA of `PollyO` (OSU 1108.001) was 117.6 cm.sup.2, or 146%
of `Jefferson`. In previous trials, TCA of `Jefferson` has been
about 65-70% of the vigorous standard `Barcelona`, a size that
pleases Oregon growers. Trees of `PollyO` (OSU 1108.001) are
vigorous, and their globose growth habit (FIG. 2) should be
grower-friendly (easy to manage).
In the first trial, mean total nut yield (2013-16) of `PollyO` (OSU
1108.001) was 29.4 kg compared to 24.3 kg for `Jefferson` (Tables
1-2). Yield efficiency, the ratio of yield to TCA, adjusts yield
for differences in tree size. Yield efficiency of `PollyO` (OSU
1108.001) was 0.251 kg/cm.sup.2 which is not significantly
different from `Jefferson` (0.261 kg/cm.sup.2). In the second
trial, mean total nut yield was 23.46 kg for `PollyO` (OSU
1108.001) which is significantly higher than the 16.91 kg for
`Jefferson` (Tables 3-4). Yield efficiency was 0.201 kg/cm.sup.2
for `PollyO` (OSU 1108.001) which is not significantly different
from `Jefferson` (0.210 kg/cm.sup.2).

Nut and Kernel Defects.
Samples of 100 nuts were cracked from each tree in each year. No
problems were noted in either trial, although many differences
among selections in the trials lack statistical significance
because of the small number of replications. In both trials (Tables
3-5), `PollyO` (OSU 1108.001) showed a high percentage of good
nuts, and low percentages of blanks, brown stain, poorly filled
nuts, twins, and kernels with black tips. In the first trial, the
frequency of moldy kernels (2.56%) was similar to `Yamhill` and
lower than `Jefferson`. In the second trial, the frequency of moldy
kernels (3.4%) was similar to `Jefferson` (4.3%). Percent kernel
(the ratio of kernel weight to nut weight) for `PollyO` (OSU
1108.001) was 47.9% in the first trial based on well-filled nuts,
and 46.9% in the second trial based on field-run nuts. In the same
trials, the percent kernel for `Jefferson` was 45.7% and 44.4%,
respectively. Yields of kernels per acre would be high for `PollyO`
(OSU 1108.001). In the two trials, nut yields of `PollyO` (OSU
1108.001) were consistently good and the nuts consistently
well-filled. In contrast, `Yamhill` trees occasionally set very
heavy nut crops, and the nuts can be so poorly filled that the
kernels are not marketable. This was the case for `Yamhill` in the
final year of the first trial, when 27% of the nuts were poorly
filled.

Nut and Kernel Characteristics.
`PollyO` can be used for the blanched kernel market as a companion
for `Wepster` and `McDonald`, and an alternative to `Yamhill`. The
nut shape is nearly round and lends itself well to sizing and
cracking (FIG. 3). The shells are thin and easy to crack, and most
kernels remain whole when the shell is broken. The kernel size of
`PollyO` is small, similar to `McDonald` but larger than `Wepster`
and `Yamhill`. The amount of fiber on the pellicle was rated on a
scale of 1 (no fiber) to 4 (heavy fiber). Raw kernels have fibrous
pellicles (mean rating 3.3) and thus are not particularly
attractive. Pellicle removal (blanching) is rated on a scale of 1
(complete pellicle removal) to 7 (no pellicle removal), with
ratings <4.0 being desired. Most of the pellicle on `PollyO`
kernels is removed from the kernels with dry heat in the blanching
process (ratings=3.7 and 3.5 in the first and second trials,
respectively) which is better than `Yamhill` (ratings=5.0 and 5.1)
and `Jefferson` (ratings 4.3 and 4.6). Blanching removes about half
of the pellicle from `Barcelona` kernels (FIG. 3). Kernel texture,
flavor and aroma were evaluated in September 2016 or 2017. Tasters
consider kernel quality to be excellent, and well-suited for use in
baked goods and chocolate products.
Nut Maturity Date.
The nuts of `PollyO` are borne in clusters of 3-4 in husks about
25% longer than the nuts (FIG. 4). The husks are slit down the
side, and flare open as they dry at maturity (FIG. 6). About 92% of
the nuts fall free of the husk at maturity (range 85-97%). The
other 8% of the nuts would come out of the husks as they moved
through the harvester. When mature, the shells are light tan in
color. Nuts in the first trial were hand-harvested and notes
recorded at the time of harvest. Notes included the date, the
percentage of nuts on the ground (as opposed to in the tree), and
the percentage of the nuts on the ground that were free of the husk
(as opposed to inside the husk). More than 2000 trees are harvested
by hand every fall, visiting a block once every 7 to 10 days, and
harvesting a tree if >70% of the nuts are on the ground. Thus
the percentages in the first trial are estimates. The harvest dates
and percentage down indicate that maturity of `PollyO` is 10-14
days earlier than `Barcelona`, allowing harvest before the start of
the rainy season. To more precisely estimate nut maturity, four
trees each of `PollyO`, `Jefferson` and `Yamhill` in the first
trial and four trees of `Barcelona` in adjacent rows were harvested
by hand at weekly intervals in the final year of the trial (2016).
The maturity curves from the 2016 harvest (FIG. 7) show that nuts
of `PollyO` drop a few days earlier than `Yamhill` and 10-14 days
sooner than `Barcelona`. Average harvest dates compared to
`Barcelona` are about 14 days early for `McDonald`, 10 days early
for `Yamhill` and 7 days early for `Wepster`. `Jefferson` nuts
mature with `Barcelona` or up to three days later. Nuts in the
second trial were annually raked and fed through a Mave harvester.
Prior to harvest, the percentage of nuts on the ground was
estimated weekly in the final year of the trial, beginning on
September 15 (FIG. 8). The nut drop estimate curves indicate that
nut maturity of `PollyO` is between `McDonald` and `Yamhill`.
Plantings of `PollyO` with `McDonald` and `Wepster` with additional
`York` pollinizer trees would allow harvest to begin two weeks
earlier than `Barcelona`. Nuts were harvested from four cultivars
in the second trial on five dates (FIG. 9), and confirmed the
relative maturities. Early harvest before the rainy season begins
results in lower drying costs and higher nut quality.
Incompatibility and Pollinizers.
Trees of `PollyO` set a moderate to high amount of catkins that
shed copious amounts of pollen in early mid-season, with
`McDonald`, `Wepster`, `York` and `Yamhill`. Pollen has been
collected and used in several controlled pollinations, and both
quantity and viability appear to be very good. Pollen of `PollyO`
has germinated well on agar plates (85% in 2014, 81% in 2015 and
48% in 2017), in contrast to `Barcelona (36%, 36% and 40%,
respectively). `PollyO` has incompatibility alleles S.sub.2 and
S.sub.10 as determined by fluorescence microscopy. Both alleles are
expressed in the females, but only S.sub.10 is expressed in the
pollen because of dominance. By convention, alleles expressed in
the pollen are underlined.
Time of pollen shed and female receptivity were recorded weekly
from mid-December to mid-March and are shown for four years
(2014-2018) (FIGS. 10-13). Female inflorescences of `PollyO`
emerged in early mid-season and were fully receptive in
mid-January, overlapping the period of receptivity of `McDonald`,
`Wepster`, `Yamhill` and `York`. Time of pollen shed peaks in the
first half of February, about ten days later than the other four
cultivars. There would be good overlap between female receptivity
and pollen shed for any combination of these five cultivars, which
are also cross-compatible in all combinations and directions. Many
orchard designs are possible using `PollyO` (S.sub.2 S.sub.10),
`McDonald` (S.sub.2 S.sub.15) and `Wepster` (S.sub.1 S.sub.2).
Inclusion of a few trees of the pollinizer `York` (S.sub.2
S.sub.21) is also recommended. `Yamhill` (S.sub.8 S.sub.26) is also
a suitable pollinizer for `PollyO` but its tree is lower in vigor
and its kernels do not blanch well. Pollen of `Jefferson` (S.sub.1
S.sub.3) is also compatible on females of `PollyO`, but `Jefferson`
females emerge very late in the season, and `Jefferson` has large
nuts for the in-shell market whereas all of the others are for the
kernel market. Pollen of `Dorris` (S.sub.1 S.sub.12), `Sacajawea`
(S.sub.1 S.sub.22) and `Barcelona` (S.sub.1 S.sub.2) is also
compatible on females of `PollyO`; of these only `Dorris` is highly
resistant to EFB. Pollen of `Felix` (S.sub.15 S.sub.21) and `Theta`
(S.sub.5 S.sub.15) is also compatible but they shed pollen too late
to be effective pollinizers for `PollyO`. Pollen of `Tonda di
Giffoni` (S.sub.2 S.sub.23) (unpatented) is incompatible because it
expresses S.sub.2. Inclusion of `McDonald` and `Wepster` as
companion cultivars in the orchard results in no loss in total nut
yield. Alternative orchard designs include plantings of different
cross-compatible cultivars in adjacent rows. The inclusion of
pollinizers with a high level of EFB resistance would eliminate the
need for fungicide control in the entire orchard.
Pests and Diseases.
Based on DNA marker data, `PollyO`, like `McDonald`, `Wepster` and
`Yamhill`, has a very high level of resistance to EFB conferred by
a dominant allele from `Gasaway` through the grower selection
`Zimmermean`, so fungicide applications are not needed. RAPD
markers 152-800 and 268-580 that flank the resistance allele in
`Gasaway` are present in `PollyO`, and these markers are
transmitted to its seedlings. Additional RAPD markers linked to
resistance are also present. No cankers have been observed on the
11 trees of `PollyO` in the yield trials, while several cankers
have been noted on adjacent trees of susceptible genotypes. During
the trials, a nearby heavily infected commercial orchard provided
high EFB disease pressure on all plantings. `PollyO` and many other
selections were propagated by tie-off layerage of the suckers in
2013. Eight trees of `PollyO` were potted and grown in the
lathhouse in the summer of 2014 and exposed to EFB under a
structure topped with diseased branches in spring 2015.
Unfortunately, inspection in December 2016 showed that very few
trees became infected, even the highly susceptible check `Ennis`
(unpatented). It seems that the diseased branches were of
low-quality inoculum due to freeze injury, as no useful data were
provided by this exposure.
Susceptibility to bacterial blight caused by Xanthomonas campestris
pv. corylina has not been quantified, but no trees in the two
trials were affected.
Susceptibility to big bud mite (primarily Phytoptus avellanae Nal.)
was rated in the first trial (Tables 5-6) after leaf fall once per
year for five years (December 2012-2016). The scale was from 1 (no
blasted buds) to 5 (many blasted buds), with chemical control
considered unnecessary for cultivars with a mean rating <3.3.
The average ratings indicate high resistance for `PollyO` (1.15)
and `Jefferson` (1.34), and an intermediate rating for `Gamma`
(2.96). Blasted buds are very rare on `PollyO`, so chemical
applications should not be necessary to control bud mite.
Microsatellite Marker Analysis:
Twenty microsatellite (simple sequence repeat) markers were used.
PCR products were multiplexed post-PCR and sized using capillary
electrophoresis (Tables 12-13, and see for example Bassil et al.,
Acta Horticulturae 686:105-110, 2005; Gokirmak et al., Genetic
Resources and Crop Evolution 56:147-172, 2009; Gurcan and
Mehlenbacher. Molecular Breeding 26:551-559, 2010; Gurcan et al.

Table 14 shows allele sizes at 20 microsatellite markers for
`PollyO`, its parents `OSU684.104` and `OSU 669.104`, cultivars and
selections that appear in the pedigree of `PollyO` (`Mortarella` to
`Montebello`), and four kernel cultivars (`Yamhill`, `Tonda
Pacifica`, `McDonald` and `Wepster`). `PollyO` is easily
distinguished from all others shown in Table 13. `PollyO` is
different from its female parent `OSU 684.104` at 11 of the 20
marker loci. `PollyO` is different from its male parent `OSU
669.104` at 14 of the 20 marker loci. `PollyO` is the same as both
parents at 3 loci. `PollyO` is the same as one parent at 9 loci.
`PollyO` is different from both parents at 8 loci. Allele A614-125,
Allele A616-144, Allele B617-285, Alleles B709-223 and B709-227,
