it not showing in fields in plugin manger. can please tell how fix problem?

google friend, found in single search , first few entries matched.

http://docs.joomla.org/standard_form_field_types

so fields indeed still intact. blank? maybe there's markup errors, can display in plugin admin?

maybe xml structure has changed, reference or compare against joomla plugin works in joomla version...that too.
