In the latest release of Tk you can use $options->options() to reset the list whenever you like. Here is my version of your test case

#!/usr/bin/perl
use strict;
use warnings;
use Tk;

my $mw = MainWindow->new;
$mw->geometry("300x300");

my $var =1;
my ($major, $other);

my @options = ('one', 'two', 'three', 'four', 'five');

my $topics1=$mw->Radiobutton(-text =>'Selection 1', -value => '0',
        -variable => \$major,  -command => sub {&do_smth('1')})->pack(
+);

my $topics2=$mw->Radiobutton(-text =>'Selection 2', -value => '1',
        -variable => \$major, -command => sub {&do_smth('2')})->pack()
+;

my $topics3=$mw->Radiobutton(-text =>'Selection 3', -value => '3',
        -variable => \$major, -command => sub {&do_smth('3')})->pack()
+;


my $options=$mw->Optionmenu( -options => [@options], -variable => \$ot
+her,
                -command => [sub {&do_more($major, $other);}])->pack()
+;


MainLoop;


sub do_smth{
    my $selection = shift;
    if ($selection == 2) {
        $options->options ([@options, 'six' , 'seven']) 
    } else {
        $options->options ([@options] )
    }
    $var='more' unless ($selection == 2);
}

sub do_more{
        my ($major, $other) = @_;
        print "do this: $other while Selection was $major\n";

}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
