categories - display only root category in archive list

I want to display only the root category of a post in the summary on the archive page. Now I have this code snippet, <?php the_category( '', 'single' ); ?>, but it's showing the root category name in front of the other categories.

I have no clue how to adapt the snippet so it will only show the root (parent) category.

Ive found this code snippet and it works perfectly.

$category = get_the_category();
$parent = get_cat_name($category[0]->category_parent);
if  (!empty($parent)) {
   echo '' . $parent;
} else {
   echo '' . $category[0]->cat_name;
}
