Point to warmth of crop (5)

Ross

I believe the answer is:

wheat

'crop' is the definition.

'point to warmth' is the wordplay.
'point' becomes 'w' (W is an example).
'to warmth' becomes 'heat' (synonyms).
'w'+'heat'='WHEAT'

'of' acts as a link.

(Other definitions for wheat that I've seen before include "Grain crop" , "Source of flour" , "Bread ingredient" , "(Pasta) cereal" , "cereal's required" .)

I've seen this clue in The Mirror.
