Professional apple gardening is bound to particular
risks, of which is essential losses of a harvest because
of diseases. An apple scab, the caused Venturia
inaequalis (Cooke) G. Winter, brings the greatest
loss. The main approach in monitoring of a scab of an
apple-tree is creation of grades, steady against
pathogen. In the present work we have carried out
phytopathology testing of generations of the seedlings
received from the free pollination of six forms of a
crab of Malus orientalis from a collection MOS VIR
(Maykop) characterized by a relative resistance to the
apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both
of natural population of a scab, and of strains of
pathogen of various cultivars and geographical origin.
When carrying out padding infection increase in force
of an infectious background that can be bound to
selection of the plants of biotypes of a fungus that are
most adapted for genotypes was noted. It is
recommended for precise elimination of unstable
plants at selection at early stages of an ontogenesis to
carry out more than one serial infection during the
season. By results of the phytopathological testing,
we highlighted three Malus orientalis forms from the
six studied No. 17982, 17985 and 3080 the most
perspective stability genes for an introgressiya in a
cultural gene pool of an apple tree
