Having several husbands on play production - dull! (9)

Ross

I believe the answer is:

polyandry

I'm a little stuck... Click here to teach me more about this clue!

'having several husbands' is the definition.
I can't judge whether this defines the answer.

'on play production dull' is the wordplay.
'production' indicates anagramming the letters.
'dull' becomes 'dry' (I've seen this before).
'on'+'play'='onplay'
'onplay' anagrammed gives 'polyan'.
'polyan'+'dry'='POLYANDRY'

Can you help me to learn more?

(Other definitions for polyandry that I've seen before include "Practice of a woman having many husbands" , "marital arrangement" , "Practice of having more than one husband at a time" , "System of having multiple husbands" .)
