For
study
of
the
inheritance
of
the
force
of
fruit
putting
out
were
taken
contrastive
parents
-
Vkusny
-
j,
U,
o
(green
back
on
the
fruit
base,
plumy
-
type
fruit
form)
and
Volganin
-
j,
u,
O
(without
green
back,
round
fruit)
.
Both
parents
have
jointless
pedicels
(gene
j)
that
gives
possibility
to
determine
the
force
of
fruit
putting
out
once
from
plant
with
dynamometer
having
the
special
fixing
seizure
for
fruit
.
In
P

-
P

-
F
1
from
9
to
20
plants,
and
in
F
2
-
92
plants
were
evaluated
.
Every
plant
was
estimated
by
10
fruits
and
average
forces
of
putting
out
for
all
individual
plants
were
calculated
.
After
that
all
variability
of
plants
by
force
of
fruit
putting
out
(P
1
-
P
2
-
F
1
-
F
2
)
we
divided
by
10
classes
and
determined
the
frequency
distribution
for
the
parents
and
F
1
-
F
2
hybrids
.
The
parents
were
differed
by
borders
of
varying
of
trait
.
Their
average
data
of
force
differed
almost
in
2
times
(0
.
84
and
1
.
56
kg)
(Table

.
In
F
1
hybrid
the
intermediate
inheritance
of
trait
was
observed
.
Comparing
of
borders
of
varying
of
the
trait
of
parents
and
hybrids
we
determined
the
number
of
F
2
plants
with
weak
force
of
putting
out
(P
1
-
type)
and
the
number
of
rest
plants
.
The
number
of
plants
with
weak
force,
similar
to
P
1
,
was
16
and
its
relation
to
the
rest
plants
16:76
.
This
segregation
corresponds
to

In
accordance
with
rules
of
genetic
nomenclature
the
symbol
fpo
for
monogene
of
weak

of

it
is
proposed
.
Its
allelic
gene,
determining
more
force
of
putting

in
the
Volganin
j
variety,
may
be
designated
as
fpo

Analogical
monogenes
of
force
of
fruit
putting
out
from
plant
in
the
cucumber
crop
were
earlier
already
revealed
(Avdeyev

.

.
,
1994)
.
In
our
experiments
with
tomato
some
traits
of
every
F
2
plant
were
described
.
The
study
showed
that
there
is
not
visible
difference
by
force
of
putting
out
between
F

-
plants
with
u

gene
and
plants
with
U
-
gene
(1

39
kg
against
1
.
31
kg;
difference

06
times),
but
considerable
difference
between
F
2
plants
distinguished
by
fruit
form
is
manifested
.
Plants
with
plumy
-
type
form
of
fruits
had
strength
of
putting
out
1
.
33
times
less
than
the
rest
group
of
plants
(1
.
07
against
1
.
42
kg)
.
Similarly,
considerable
difference
between
such
groups
of
plants
in
the
study
of
F
2
(VM
-
93
x
Slivovidny
Shtambovy)
was
seen
(1
.
49
times)
.
The
comparing
of
the
average
forces
of
fruit
putting
out
in
groups
of
F

-
plants,
differed
by
genotypes,
showed
differences

and

times
.
From
experiments
we
made
conclusion,
that
the
main
gene,
controlling
the
weak
force
of
fruit
putting
out
from
pedicel,
is
connected
with
gene
"o"
-
plumy
-
type
(ovate)
form
fruit
.
Small
genes
with
forces
of
influence
on
trait
3,5
-
7
times
less
than
the
main
genes
(fpo,
fpo
-
1)
are
connected
with
genes
d,
j
-
2
and
"u"
(in
some
varieties)
and
may
be
with
others
.
They
cause
of
some
level
of
transgression
of
the
trait
in
F
2
-
plants
.
The
genetic
analysis
of
the
crossing
over
between
genes
fpo
(fpo

and
o
(O)
was
carried
out
.
The
frequency
of
recombination
with
usual
method
was
calculated
