The UW-Madison potato breeding program has a new vegetable transplanter! One of the long-term goals of the Potato 2.0 effort is to utilize transplants for first year production instead of greenhouse minitubers. We have a lot to learn about optimizing this method, but it’s an exciting beginning.

The Tan lab at Universtiy of Maine shared with the community plants and tubers from wild, diploid, and tetraploid potato.

The Tan lab at the University of Maine harvesting primary dihaploids. The lab harvested about 400 lines by hand this year!

Interesting flowers from dihaploid potato plants grown in the field by the Douches lab at Michigan State University. Note the black/white petal flower! All photos taken by Kate Shaw at Michigan State University. Click the link below to see more images.
