My code is

<select id="asset_id" class="asset_id" name="asset_id[][]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option> 
<option class="dropdownlist">Asset Id 2</option> 
<option class="dropdownlist">Asset Id 3</option>
</select>
</td>
</tr>

<tr>
<td><input type="text" name="batch_code[]"/></td>
<td><input type="text" name="description[]"/></td>
<td><input type="text" size="12" name="qty[]"/></td>
<td>
<select id="asset_id" class="asset_id" name="asset_id[][]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option>

Try this:

<tr>
<td><input type="text" name="batch_code[]"/></td>
<td><input type="text" name="description[]"/></td>
<td><input type="text" size="12" name="qty[]"/></td>
<td>
<select id="asset_id" class="asset_id" name="asset_id[0][]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option> 
<option class="dropdownlist">Asset Id 2</option> 
<option class="dropdownlist">Asset Id 3</option>
</select>
</td>
</tr>

<tr>
<td><input type="text" name="batch_code[]"/></td>
<td><input type="text" name="description[]"/></td>
<td><input type="text" size="12" name="qty[]"/></td>
<td>
<select id="asset_id" class="asset_id" name="asset_id[1][]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option> 
<option class="dropdownlist">Asset Id 2</option> 
<option class="dropdownlist">Asset Id 3</option>
</select>
</td>
</tr>

Update: I have tried this out of curiosity, and the results are as required:

  ["asset_id"]=>
  array(2) {
    [0]=>
    array(2) {
      [0]=>
      string(10) "Asset Id 1"
      [1]=>
      string(10) "Asset Id 2"
    }
    [1]=>
    array(2) {
      [0]=>
      string(10) "Asset Id 1"
      [1]=>
      string(10) "Asset Id 3"
    }
  }

Why Using Two dimension Array. Use asset_id[] instead of asset_id[][]

Correct code

<tr>
<td><input type="text" name="batch_code[]"/></td>
<td><input type="text" name="description[]"/></td>
<td><input type="text" size="12" name="qty[]"/></td>
<td>
<select id="asset_id" class="asset_id" name="asset_id[]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option> 
<option class="dropdownlist">Asset Id 2</option> 
<option class="dropdownlist">Asset Id 3</option>
</select>
</td>
</tr>

<tr>
<td><input type="text" name="batch_code[]"/></td>
<td><input type="text" name="description[]"/></td>
<td><input type="text" size="12" name="qty[]"/></td>
<td>
<select id="asset_id" class="asset_id" name="asset_id[]" multiple="multiple">
<option class="dropdownlist">Asset Id 1</option> 
<option class="dropdownlist">Asset Id 2</option> 
<option class="dropdownlist">Asset Id 3</option>
</select>
</td>
</tr>
