Smooth-skinned peach (9)
I believe the answer is:
nectarine
'smooth-skinned peach' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for nectarine that I've seen before include "fruity" , "Luscious fruit" , "Peach-like fruit" , "Juicy fruit" , "Smooth-skinned variety of peach" .)
