During
a
study
designed
to
integrate
the
classical
and
RFLP
maps
of
the
short
arm
of
chromosome
I
(reported
by
Balint
-
Kurti
et
al
.
1995),
a
number
of
markers
that
had
been
previously
suggested
to
map
to
chromosome
1
were
assessed
.
The
phenotypes
conferred
by
two
of
these
markers,
in
(indiga,
Stubbe
1958)
and
dp
(drooping
leaf,
Yu
and
Yeager
1960),
were
found
to
resemble
those
conferred
by
two
known
chromosome
1
markers,
com
(complicata)
and
dgt
(diageotropica),
respectively
.
In
a
separate
study
comparing
markers
affecting
anthocyanin
production,
the
phenotype
conferred
by
pu
-
2
(pulvinata
-
2,
Stubbe
1965)
was
found
to
resemble
that
conferred
by
al
(anthocyanin
loser)
.
Experiments
were
carried
out
to
determine
the
allelism
or
otherwise
of
these
markers
.
To
test
for
allelism
between
in
and
com
,
the
cross
GCR703
in
-
imb
x
CLS3483
au
tl
-
com
was
performed
and
the
F
1
progeny
were
found
to
be
wild
type
for
imb
and
au
tl
,
confirming
the
cross,
but
to
have
the
indiga/complicata
phenotype,
indicating
allelism
between
in
and
com
.
To
test
for
allelism
between

and
the

progeny
were
found
to
be
wild
type
for
scf
,
c,
a
and
rvt
,
confirming
the
cross,
but
to
have
the
drooping
leaf/diageotropica
phenotype,
indicating
allelism
between
dp
and
dgt
.
Finally,
to
test
for
allelism
between
pu
-
2
and
al
,
the
cross
LA973
pu
-
2
u
x
GCR382
al
u
+
was
performed
using
LA973
as
the
female
parent
and
the
F
1
,
progeny
were
found
to
have
the
putida/anthocyanin
loser
phenotype,
indicating
allelism
between
pu
-
2
and
al
,
and
to
have
non
uniform
fruit
(
u
+
),
confirming
the
cross
.
Regardless
of
the
order
of
precedence
in
the
discovery
and
naming
of
these
mutations,
we
suggest
that
the
well
known
names
com,
dgt
and
al
should
be
retained
in
preference
to
the
more
obscure
names
in,
dp
and
pu
-
2
,
which
should
be
altered
to
com
in
dgt
dp
and
al
pu
-
2
,
to
reflect
both
their
origin
and
their
location
at
the
well
mapped
com,
dgt
and
al
loci
,
respectively
.
