9 accepting new crate of fruit (9)
I believe the answer is:
Here is my best explanation:
'fruit' is the definition.
(nectarine is a kind of fruit)
'9 accepting new crate' is the subsidiary indication.
'9' becomes 'nine' ('nine' can be a synonym of '9').
'accepting' means one lot of letters goes inside another.
'new' indicates an anagram.
'crate' anagrammed gives 'ectar'.
'nine' enclosing 'ectar' is 'nectarine'.
'of' is the link.
(Other definitions for nectarine that I've seen before include "fruity", "Smooth-skinned variety of peach", "Fruit - aren't nice (anag)", "type of tree", "Trace nine to a kind of peach", "Kind of peach with thin skin and no down", "creating a sort of jam", "Peach-like fruit", "Variety or mutation of a peach" and "Luscious fruit".)
