Our local seed production agronomist spent time in S Tex growing seed milo.  He says we'll never see (I know, never say never) RR milo because of the possibility of it crossing with Johnsongrass and shattercane.

Also, I'm told one of milo's big selling points right now is it's all non-GMO.  If we have GMO milo it takes away a price advantage milo has right now.
