Spoil hybrid seed container (9)
I believe the answer is:
desecrate
'spoil' is the definition.
(I've seen this before)
'hybrid seed container' is the wordplay.
'hybrid' indicates an anagram (I've seen this in other clues).
'container' becomes 'crate' (crate is a kind of container**).
'seed' with letters rearranged gives 'dese'.
'dese'+'crate'='DESECRATE'
(Other definitions for desecrate that I've seen before include "Secreted a means to treat something sacred with disrespect" , "Treat (something sacred) with great disrespect" , "Spoil" , "Violate the sacred" , "Profane" .)
