Solanum juzepczukii

Bukasov

Solanaceae


There is no universally accepted treatment for the various species that make up the potatoes. We are following the treatment of Spooner D.M. Et al in 2007 in the 'Proceedings of the National. Academy of Science USA 104: 19398-19403, in which only four distinct genera are maintained - viz; S. Ajanhuiri (diploid forms); S. Curtilobum (pentaploid forms); S. Juzepczukii (triploid forms) and S. Tuberosum, which is subdivided into two cultivar-groups (Andigenum Group of upland Andean genotypes containing diploids, triploids and tetraploids, and the Chilotanum Group of lowland tetraploid Chilean landraces)[

Propagation

Seed - sow early spring in a warm greenhouse. Prick out the seedlings into a fairly rich compost as soon as they are large enough to handle and grow them on fast. Plant them out after the last expected frosts.
Division. Harvest the tubers in autumn after the top-growth has been cut back by frost. Store the tubers in a cool frost-free place overwinter and replant in mid spring.
