Bread variety (3)

I think it could be either:

oat

rye

'bread variety' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for rye that I've seen before include "East Sussex resort" , "Cereal - liquor" , "Grain used in flour and whiskey" , "Gypsy gentleman" , "J D Salinger novel 'The Catcher in the ...'" .)

I've seen this clue in the USA Today, the Sydney Morning Herald, The Sun, the Universal and the Penny Press.
