Landrace Breeding Potatoes and Other Tubers

Seedlings from the Cultivariable Wide Tetraploid TPS mix

Recently, I’ve been getting a lot of questions about “landracing” potatoes and some of the other crops that I work with.  I take this as a sign that Joseph Lofthouse‘s new book, Landrace Gardening, is selling well.  I highly recommend it.  If you have any interest in backyard vegetable breeding, click on that link and […]

Potato Aerial Tubers

There are some questions about potatoes that I get over and over again, like whether or not potato towers work, what the mysterious fruits on potato plants are, and whether or not greened potatoes are dangerous.  This post is about one of those frequently asked questions that I hadn’t gotten to yet: why is my […]

Everything You Need to Know About Indeterminate Potatoes

Lime green foliage and long leaves characteristic of a diploid domesticated potato

Ten years ago, almost nobody was talking about indeterminate potatoes.  Over the years, interest has crept up to the point where I now receive hundreds of inquiries each year about which of the varieties that I offer, or which potato varieties in general, are indeterminate.  This is surprising, because it is a rather obscure topic […]

A Change to Our International Shipping Policy (Again)

It has been about three years since I decided to end international shipping.  Since then, I have received numerous requests to reconsider that policy, many of which were persuasive and appeal to my libertarian leanings.  I have decided to resume international shipping of seeds only.  I will not send roots and tubers outside the USA.  […]

Crossing Between Solanum maglia and Domesticated Diploid Potatoes (Part 2)

Tubers of a Solanum maglia x domesticated diploid hybrid

In part 1 of this post, I discussed the reasons for attempting to hybridize domesticated diploid potatoes with Solanum maglia.  The major reason is simple exploration, but S. maglia also has some interesting traits that could be valuable.  For one thing, the plants are large, with broad foliage, and might help to produce larger, higher […]

Review: Clancy TPS Potato Variety

Tuber of the TPS potato (Solanum tuberosum) variety 'Clancy'

Clancy is a 2019 introduction from Bejo Seeds, a large breeder and seed producer, based in the Netherlands, who have trademarked the phrase, “True Botanical Potato Seed,” thereby cornering the market on redundancy, I guess.  A friend who ordered more than he needed kindly sent me the remainder of his packet and I thought it […]

The Highland Potato with Its Own Song

Flower of the potato (Solanum ajanhuiri) variety 'Jancko Ajawiri'

Solanum ajanhuiri is a native Andean potato, grown at the highest elevations suitable for cultivation (around 13,000 feet) in Bolivia and Peru, where it can survive due to its frost and drought resistance.  There is a Bolivian folk song for the planting of this potato, given here from Huaman (1980), after translation from Aymara to […]

Crossing Between Solanum maglia and Domesticated Diploid Potatoes (Part 1)

Cut S. maglia berry

Solanum maglia is a wild potato from Chile.  It is kind of an oddity, because it grows in a region of South America quite some distance from both other populations of wild potatoes and from the region where domesticated potatoes were originally grown in Chile.  Unlike the vast majority of wild potatoes, it is a […]
