Identificación molecular de Potyvirus infectando cultivos de papa en el oriente de Antioquia (Colombia)

Acta Biológica Colombiana, 2018
Los potyvirus son uno de los grupos de virus más limitantes en los cultivos de papa (Solanum tuberosum y S. phureja) en el mundo, siendo PVY, PVV y PVA las especies más prevalentes.

Rendimiento de cultivares de papa (Solanum tuberosum L.) amarillos precoces del grupo Phureja

Agronomía Mesoamericana, 2018
El grupo Phureja (Solanum tuberosum L.) ha sido poco estudiado en Perú, a pesar de, su calidad culinaria, nutricional e industrial, y el riesgo de erosión al que ha estado sometido en las últimas décadas.

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

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.

Genome‐wide association studies and genomics‐informed breeding for tuber dormancy in tetraploid potatoes

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Upon harvest, potato (Solanum tuberosum L.) tubers enter a dormant state and do not sprout even under favorable conditions. Early dormancy break causes tuber spoilage and reduces postharvest quality. Common sprout control methods may compromise tuber quality, raise health and environmental concerns, and increase costs.

Evaluation of hybrids of So/anum po/yadenium Greenm for white worm resistance in potatoe (Premmotripes voraxHustoche.) Evaluación de híbridos de Solanum polyadenium Greenm. Para resistencia al gusano blanco de la papa (Premnotrypes vorax Hustache)

Agronomía Colombiana, 1993
Four Solanum polyadenlum crossed with Solanum berthanltil, Solanum chacoense and Solanum phureja were evaluated for resistance to the Andean potato weevil (Premnotrypes vorax Hustache).

INCORPORATION OF GLANDULAR TRICHOMES INTO AN ADVANCED SOLANUM PHUREJA-STEN0TOMUM HYBRID POPULATION [PDF]

HortScience, 1991
A hybrid diploid potato population ( Solanum phureja x Solanum stenotomum ) with superior horticultural traits has been developed for breeding purposes. Because this highly advanced population has no resistance to potato virus Y (PVY), and because PVY pressure is very high in North Carolina ...

Changes in polyamine content are related to low temperature resistance in potato plants

Acta Biológica Colombiana, 1999
Polyamine content and variation within a 48 hour simulated freezing stress were determined in plants with different low temperature resistance. Genotypes Solanum acaule, Solanum phureja, transgenic Solanum tuberosum c.v.
