In have added the solution to sharepoint 2013 and deployed using GUI for a site collection. But i am unable to find form based authentication management features in Site Collection features of site collection. Can you please tell me what would be the reason?

As long as the solution was successfully deployed to that web application, you should see it in 'Site Collection Features'. Also - make sure you're checking 'Site Collection Features' and not just 'Site Features'.
