Type of apple (6)
I believe the answer is:
russet
'type of apple' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for russet that I've seen before include "Brown; apple variety" , "Apple - colour" , "Autumn red" , "Reddish-brown - type of apple" , "Autumnal reddish brown" .)
