Fruit in orchard's first row (6)
I believe the answer is:
orange
'fruit' is the definition.
(orange is a kind of fruit)
'orchard's first row' is the wordplay.
'first' indicates taking the first letters.
'row' becomes 'range' (I've seen this before).
The first letter of 'orchard' is 'o'.
'o'+'range'='ORANGE'
'in' acts as a link.
(Other definitions for orange that I've seen before include "shade" , "Between red and yellow on the spectrum" , "Loyalist colour" , "An ogre (anag.)" , "African flower" .)
