Kelle over at The Never Done Farm has a great comprehensive list of seed companies owned by Monsanto. I agree with her that we homesteaders must make a stand against their greed. It is up to us to save heirloom seeds for future generations and if we don't make the stand now, by making sure that we do not purchase Monsanto seeds, then they will do whatever it takes to destroy our heirlooms. So please check out her list of Monsanto owned seed companies
Blessings from the farm!
