EDENTM A
non-browning apple cultivar
‘EdenTM’ is
a dessert apple (Malus × domestica Borkh.)
with improved firmness and crispness,
high quality flesh and much longer
shelf life than ‘McIntosh’ and
‘Cortland’. The fruits have superior
flavor and do not fall from the tree
at maturity. The flesh is juicy, firm,
crisp and resistant to bruising. No
browning occurs after cutting, make it
an excellent candidate for fresh fruit
slices, fruit salad, dried apple chips
and processing (juice, cider).

Origin: 'EdenTM',
also tested as SJCA38R6A74, originated
from a cross between 'Linda' and
Jonamac, at Agriculture and Agri-Food
Canada (AAFC), Horticultural Research
and Development Center (HRDC),
St.-Jean-sur-Richelieu, Quebec.
Tree characteristics: ‘EdenTM’ trees
are upright
to upright-spreading, semi-vigorous,
with wide branch angles. New shoots
are hairy. Fruit are borne on spurs,
and the shoots tend to droop. Leaves
are oblong to slightly obovate, doubly
serrate with hairy undersides,
cuspidate apex and cuneate to obtuse
base. The leaf length: width ratio is
1.96 and the petioles are 3 to 6 cm
long. ‘EdenTM’
trees are hardy in Quebec, where
average winter minimum temperature is
–25 ºC. There have been no signs of
powdery mildew [Podosphaera
leucotricha (Ell.
& Ev.) Salm.], fireblight [Erwinia
amylovora (Burr.) Winslow
et al.] or scab [Venturia
inaequalis (Cke.)
Wint.]infections on leaves during the
evaluation period.
Flower characteristics: Flowering
starts 5 days before ‘McIntosh’.
Fruit characteristics: ‘EdenTM’
fruits are globose, oblate and
sometimes lopsided and irregular. The
fruit are attractive, medium to large
in size, with an average of
150 g, and are not susceptible to
bruising or browning compared to other
tested cultivars. Fruits are
susceptible to scab similar to ‘Macspur’,
‘McIntosh’ and ‘Cortland’. The fruit
skin has average thickness; the color
of the skin is washed out (faded) and
solid dark
red over a greenish-yellow ground.
Lenticel number is low near the stem
but very high near the basin. The
flesh is white, juicy, firm, crisp yet
melting, and fine textured. No
browning occurs for several hours
after the flesh is cut with a
stainless steel knife, and it remains
white until completely dried at room
temperature, probably due to its low
level of phenolic compounds as
reported previously (Khanizadeh et.
al. 2005). The
flavor is very aromatic, sweet and
acidic at optimum maturity, which is
at the end of September, one week
after ‘McIntosh’. ‘EdenTM’
is recommended for fresh eating, fruit
salad and processing (dried apple
chips) and fresh
cut similar to those used by industry.
Post Harvest, storage: The
fruits keep their firmness, juiciness
and flavor very well in standard cold
storage for 4-5 months.
Other characteristics: ‘EdenTM’
fruits are susceptible to bitter pit,
specially if the season is dry and no
irrigation is provided. The yield is
very similar to the ‘Macspur’ and
fruits are resistant to water core,
and unlike ‘Macspur’, they do not drop
at maturity, but stay on the tree for
several weeks after, even at -20 oC
which might make ‘EdenTM’ a
good candidate for ice cider
production.
Availability: The
virus free bud wood is available from
Canadian Food Inspection Agency (CFIA,
Sidney Laboratory, CFIA, 8801 East
Saanich Road, Sidney, B.C., Canada,
V8L 1H3) for North America and non
exclusive multiplication licenses can
be obtained from AAFC at Saint-Jean-sur-Richelieu.
European nurseries may obtain a
multiplication license from Meiosis
Ltd. (Bradbourne
House, Stable Block, East Malling,
Kent ME19 6DZ). A limited number of
plants are available for research
purposes from the author (SK) after
signing a non-propagation agreement.
