Abstract:
The paper proposes the
improvement of the current bitter cherry
assortment with new creations made at Iaşi,
adapted to the specific conditions from the
NE area of Romania. For the improvement
of the bitter cherry assortment with new,
productive, disease resistant cultivars with
fruits of good quality, resistant to cracking
with different maturation stages, in 1981 at
Fruit Growing Research Station (F.G.R.S.)
Iaşi - Romania has begun an action of
selection and promoting of some valuable
genotypes of bitter cherry (existent in the
spontaneous flora or in plantations from the
Iaşi county), which were being planted with
cultivars and other genotypes from all
around the country. Following the positive
and gradual selection there were selected
three biotypes of bitter cherry from which
two of them have been approved as new
cultivars in 1994, with the names „Amar
Maxut”, respectively, „Amar Galata” and
the biotype „Amar R5.P10” has been
registered in 2013 at the State Institute for
Variety Testing and Registration Bucharest
to be approved as a new cultivar. All three
bitter cherry genotypes correspond to the
objectives of the main assortment breeding.
They have a high productivity because the
natural fertility index registered values
between 36.5-63.7%, the trees have a
reduced vigour, they present a good
resistance to frost (1-9% affected buds) and
to diseases (values of I% anthracnose, 1.1-
2.8%). The fruits are high quality and the
maturation stages are at the extremities of
the cherries maturation season.
