There's been an argument going on for at least 100 years over seeds. Should they be free? Or should the people who develop them control, and profit from, their use? If they were shared, we'd have a more fluid development of agricultural technology, because all plant breeders could experiment with the best stuff. On the other hand, maybe breeders wouldn't want to engage in the hard work of experimenting if they couldn't sell their inventions for lots of money.
It used to be that those who bred new varieties of plants shared them freely, in part because it was almost impossible to control them: As soon as someone buys one of your new tomato seeds, he can use it to make a hundred more.
"If other breeders asked for our materials, we would send them a packet of seed, and they would do the same for us," he says. "That was a wonderful way to work, and that way of working is no longer with us."
All that changed after seed companies began producing hybrids, which lose their superpowers if you try to grow more of them, and as cash-strapped universities have begun patenting more and more of their seeds. But on Thursday the Open Source Seed Initiative at the University of Wisconsin-Madison released the first set of seeds with an open-source license. It is distributing 29 varieties, including broccoli, celery, kale, and quinoa.
