State of fruit, perfect one (6)
I believe the answer is:
hawaii
'state' is the definition.
(Hawaii is an example)
'fruit perfect one' is the wordplay.
'fruit' becomes 'haw' (I've seen this before).
'perfect' becomes 'ai' (I've seen this in other clues).
'one' becomes 'i' (Roman numeral).
'haw'+'ai'+'i'='HAWAII'
'of' acts as a link.
(Other definitions for hawaii that I've seen before include "islands" , "50th state of the USA" , "American state" , "State of the union" , "50th US state" .)
