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 […]

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 […]

The Practicality of Diploid Potatoes in North America

Potatoes from Cultivariables 2018 wide diploid TPS mix

The domesticated potato (Solanum tuberosum) is divided into two major groups based on the number of sets of chromosomes: tetraploids, with four sets of chromosomes, and diploids, with two sets of chromosomes.  The common potato of commerce is tetraploid.  There are also hundreds, if not thousands, of varieties of diploid potatoes, but they are mostly […]

Ken Aslet Mashua (Tropaeolum tuberosum) Tests Positive for Viruses PVS and PVY

Tubers of the mashua (Tropaeolum tuberosum) variety 'Ken Aslet'

Ken Aslet is the most common and popular variety of mashua, although it has traditionally been sold as an ornamental rather than an edible.  It has never looked quite right to me, but it tested negative for the most common viruses that infect mashua in the United States.  I recently tested plants more widely out […]
