If you pass the negative value as parameter to the val method it automatically add new blank option to the dropdownlist. Dropdown list should contains the value and text attributes for the each option then only your above method will work.
eg.
<option selected="selected" value="1">.NET Framework</option>
<option value="2">SQL Server</option>
<option value="3">ASP.NET</option>
<option value="4">C#.NET</option>
<option value="5">ADO.NET</option>
<option value="6">AJAX.NET</option>

and your method should be like -$("#dropdown").val(4);
it will select "C#.NET" option because we have provided value="4" for that option.
