In Vitro Assessment of Salt Stress Tolerance in Wild Potato Species

Agronomy, 2023
Proof of concept salt tolerance and plasticity. Wild germplasm may represent a precious source of genetic variability for salt tolerance. This study evaluated the morphological changes occurring under controlled and saline conditions in tuber-bearing S ...

Random amplified polymorphic DNA markers detected in a segregating hybrid population of Solanum chacoense × S. phureja

Genes & Genetic Systems, 1994
Reproducible random amplified polymorphic DNA (RAPD) patterns were obtained in two potato species (Solanum chacoense and S. phureja), one of their F1's, and its derived F2 population, by adjusting temperature profiles of the amplification process and template DNA concentrations (1 ng/μl reaction vol.).

Rpi-vnt1.1, a Tm-22 Homolog from Solanum venturii, Confers Resistance to Potato Late Blight

Molecular Plant-Microbe Interactions, 2009
Despite the efforts of breeders and the extensive use of fungicide control measures, late blight still remains a major threat to potato cultivation worldwide.

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

IMMUNITY TO INFECTION BY POTATO VIRUS Y AND POTATO VIRUS X IN A Solanum phureja - S. stentomum HYBRID POTATO POPULATION

HortScience, 1993
A random sample of 6000 individuals from a recombinant Solanum phureja - S. stentomum hybrid population and 250 individuals of Solanum phureja were twice inoculated with potato virus Y (PVY) strain “o” using the air brush technique.

Indexing of RNA viruses in certified and uncertified potato seed-tubers from Solanum tuberosum cv. Diacol Capiro, and S. phureja cv. Criolla Colombia: a pilot study

Archives of Phytopathology and Plant Protection, 2022
The productivity of potato in Colombia is below its potential due to continued agronomical malpractices that have resulted in a high prevalence of pathogens, particularly viruses. This work presents a pilot virus seed-indexing study using the tuber sprouting test (TST) with RT-qPCR.

Analysis of Bacterial Wilt Management Strategies From the Dynamic Perspective of Environmental Adaptation Approaches of Ralstonia solanacearum

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review reframes bacterial wilt management by analysing control strategies through the lens of the pathogen's evolutionary, physiological and ecological adaptations. This mechanism‐based approach links pathogen traits to control efficacy, guiding the development of more durable solutions.

Potato dihaploids uncover diverse alleles to facilitate diploid potato breeding

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Commercial potato (Solanum tuberosum) in North America is a clonal autotetraploid crop, which complicates breeding. Efforts are underway to convert potato to a diploid inbred‐hybrid crop, allowing breeders to more quickly meet market and environmental demands.
