and

are
not
listed
due
to
our
inability
to

them
via

.
Transmission
rate
of
the
extra
chromosome
differs
greatly
between
individual
MAALs,
however
the
phenotype
of
each
MAAL
tends
to
resemble
that
of
the
corresponding
primary
trisomic,
hence
the
recommendations
of
Rick
(TGC
37:60
-
61,
1987)
for
identifying
trisomics
at
the
seedling
stage
are
helpful
for
selecting
2n+1
progeny
of
the
MAALs
as
well
.
Intactness
of
the
S

lycopersicoides
chromosomes
in
these

has
been
tested
with
only
a
limited
number
of

hence
some
may
be

In

in

we
progressively
backcrossed

Selected

selfed

subsequent

were
selected
as
