Consolidation has increased in the international seed industry in recent decades. This chart depicts changes in ownership involving major seed companies and their subsidiaries, primarily occurring from 1996 to 2013.1 The largest firms are represented as circles, with size proportional to global commercial seed market share.2

Very useful image of the concentration of power in the seed market, is there an updated version after the Monsanto and Bayer merge?
If we can’t find a seed company on there (thank you for making the pdf searchable!) does that mean it is most likely independently owned? (Gurney’s from Greendale, IN)
Yes, it is likely it is not connected to one of these larger firms, but the most recent version I have (on this page https://philhoward.net/2018/12/31/global-seed-industry-changes-since-2013/) only captures changes through the end of 2018. Seedquest is a good resource for finding announcements of acquisitions since then.
