Title: A Report from the Balsgard Fruit Breeding Institute
Author: N. Nybom
The Balsgard Fruit Breeding Institute
is releasing the following three
new varieties this year: The summer
apple, 'Katja'; a very early plum, 'Gilbert';
and the very early-ripening and
grey mold-resistant strawberry, 'Kristina'.
The apple, 'Katja', ripens with one
of its parents, 'James Grieve'. From its
other parent, 'Worcester Permain', it
gets its mildew resistance.
of 'Katja' is a very attractive red, has
a very firm flesh, and good handling
and shipping quality.
It should make
a good commercial apple.
The plum, 'Gilbert', most closely resembles
one parent, 'Ruth Gerstetter',
and we hope it will be the earliest
plum on the market.
It has much better
dessert quality and makes a healthier
tree than 'Ruth Gerstetter'. Its other
parent is 'Ontario'.
The strawberry, 'Kristina', is a cross
between 'Senga Sengana', which it
closely resembles with regard to both
plant and fruit, and 'Valentine', from
which it has inherited extreme earliness
and resistance to Botrytis.
berries are firm enough to handle and
ship quite well.
A very interesting "departure" is
represented by the Vescana strawberry
hybrids being developed by our
Annelise Bauer and her
Rudolph Bauer, of the
Max Planck Institute, of Cologne,
Figure 1, shows the Bauers
amidst the Vescana material.
Vescanas are decaploid hybrids of
ordinary strawberries and Fragaria
vesca. They have very erect fruit
clusters, which seem to be well suited
for mechanical harvesting.
"self-hulling" (the calyx remains on the
plant), and the relatively few berries
per infloresence, ripen relatively evenly.
So far, these hybrids are still under
development, and there is as yet no
material ready for distribution.
