Episode four of the third season of Free the Seed! the Open Source Seed Initiative podcast

Do you have questions about OSSI, intellectual property rights, or plant breeding that you would like answered on this show? Please share them with us through our listener survey at http://bit.ly/FreetheSeedsurveyThis podcast is for anyone interested in the plants we eat – farmers, gardeners and food curious folks who want to dig deeper into where their food comes from. It’s about how new crop varieties make it into your seed catalogues and onto your tables. In each episode, we hear the story of a variety that has been pledged as open-source from the plant breeder that developed it.

In this episode, we'll be talking about carrot breeding in general, and two breeding projects in particular. First, Claire and Irwin will tell us about the Open Source Seed Initiative-pledged carrot breeding populations that they’ve developed at University of Wisconsin-Madison. They’ll explain how the UW-Madison Goldman Lab is able to speed up the seed production process to fit it into one single year using greenhouses and vernalization chambers.Then we’ll hear from Petra about the project to develop ‘Dulcinea’, a new variety offered by Fruition Seeds, which Irwin and Claire have collaborated on. And all three of our guests will weigh in on the basic steps of any carrot breeding project.Left: Dr. Claire Luby (Photo credit: Matthew Dillon)                  Right: Dr. Irwin Goldman (Photo credit: Matthew Dillon)Petra Page-Mann with freshly-dug 'Dulcinea' roots (Photo credit: Lisa Barker)Left: Carrot flower-heads (umbels!)
