Seedless citrus fruit (7)
I believe the answer is:
satsuma
'seedless citrus fruit' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for satsuma that I've seen before include "Orange - type of pottery" , "Loose-skinned fruit" , "Loose-skinned tangerine" , "Type of tangerine" , "sort of orange" .)
