This document discusses the dynamics between public and private seed development over time. It begins with open-pollinated seeds in the early 20th century and the rise of certified seed programs and early seed companies. Later, the development of hybrids, intellectual property protections, industry consolidation, and the resurgence of small seed companies distributing locally adapted varieties are described. The document also outlines the pedigree breeding process and issues around searching for seed, material transfer agreements, licenses, and how the author's university supports their public plant breeding program through royalty structures.
