It is reported that the Andean potato predominated in the 1700s, but the Chilean potato was introduced into Europe as early as 1811 and became predominant long before the late blight epidemics in the UK.

Comparative Analysis of the Genetic Diversity of Chilean Cultivated Potato Based on a Molecular Study of Authentic Herbarium Specimens and Present-Day Gene Bank Accessions

Finding a D-type cytoplasm in living Chilean accessions that possess two new chlorotypes indicates a replacement of native cultivars and introgression from the wild Mexican species S. demissum that was actively used in breeding as a source of race-specific resistance to late blight.

Molecular studies on the origin of the cultivated potato; a review

Molecular studies focusing on the first introductions from South America to Europe show that introductions before the late blight epidemics were already a mixture of both Andean and Chilean S. tuberosum plant material.

Potato virus Y; the Andean connection

The dating study has confirmed that human activity has dominated the phylodynamics of PVY for the last two millennia.

Complex migration history is revealed by genetic diversity of tomato samples collected in Italy during the eighteenth and nineteenth centuries

The genome of two tomato herbarium specimens conserved in the Herbarium Porticense was sequenced and yielded insights into the history of tomato loci selection, which have major implications for the understanding of tomato migration patterns and for the conservation of allelic diversity and loci recovery.

The single Andigenum origin of Neo-Tuberosum potato materials is not supported by microsatellite and plastid marker analyses

The long-standing Neo-Tuberosum derived theory of the re-creation of the modern potato from Andigenum germplasm is questioned and implications in breeding programs and phylogenetic reconstructions of potato are implications.

Wild and Cultivated Potato (Solanum sect. Petota) Escaped and Persistent Outside of its Natural Range

The occurrence of naturalized populations of the wild potato Solanum chacoense in seven sites in southern Australia, eastern China, England, New Zealand, the eastern United States, central Peru, and east-central Argentina is reported.

Genotype Number and Allelic Diversity Overview in the National Collection of Chilean Potatoes

In this work, two national collections of Chilean native germplasms were analysed via four microsatellite markers with the aims of evaluating the diversity of genotypes potentially known with the same nomenclature by farmers, and comparing allelic diversity ofnative germplasm with 44 commercial varieties.

ECUADORIAN POTATO LANDRACES: TRADITIONAL NAMES AND GENETIC IDENTITY

It showed that landraces with identical names but obvious differences in tuber morphology were almost always genetically different, and there was no clear grouping of material collected according to the regions under study that suggests extensive movement of seed potatoes all over Ecuador.

What Is the Origin of the European Potato? Evidence from Canary Island Landraces

A hypothesis that there were multiple introductions of Andean and Chilean germplasm to the Canary Islands and that the early European potato was selected from Chilean introductions long before the late blight epiphytotics of the 1840s is supported.

Nuclear and chloroplast DNA reassessment of the origin of Indian potato varieties and its implications for the origin of the early European potato

The hypothesis that early introductions of potato to Europe were solely from the Andes is reexamine with nuclear microsatellite and cpDNA analyses of 32 Indian cultivars and five Chilean landraces.

A single domestication for potato based on multilocus amplified fragment length polymorphism genotyping.

Preliminary phylogenetic analyses support a monophyletic origin of the landrace cultivars from the northern component of this complex in Peru, rather than from multiple independent origins from various northern and southern members.

Evolutionary pathway of T-type Chloroplast DNA in potato

Potato was domesticated in the Andes of South America. However, the presently worldwide-grown potato (Solanum tuberosum L. ssp.tuberosum, 2n=4x=48) has characteristic T-type chloroplast DNA that was…

Chloroplast DNA variability in old and recently introduced potato cultivars

Chloroplast DNA variability has been examined in a range of tetraploid European potato cultivars and the presence of the T type cpDNA in the cultivar Yam indicates that this genotype which is of Andigena origin shares a common cytoplasm with other 5.

Similar introduction and incorporation of potato chloroplast DNA in Japan and Europe

The chloroplast DNA (ctDNA) type was determined for most of Japanese potato varieties including both officially registered and unregistered varieties and those of unknown origin. Many modern…

The early history of the potato in Europe

Even earlier records from the Canary Isles are reported, where ‘patatas’ and ‘batata’ are clearly distinguished, and the South American word ‘papa’ for Solanum tuberosum is also used sometimes, which seems to point towards the introduction of potatoes from South America into the Canary Islands, and not, as previously assumed, directly into continental Spain.

POTATO INTRODUCTIONS AND BREEDING UP TO THE EARLY 20TH CENTURY

The pedigrees of modern potato varieties show that, although several 20th century introductions may occur in their ancestries, generally 80% or more of their genes are derived from varieties grown early this century, and that modern varieties are somewhat inbred due to relationships between their parents and ancestors.

Distribution of the 241 bp deletion of chloroplast DNA in wild potato species

A total of 566 accessions of 35 wild species were determined for presence or absence of the deletion by a simple PCR assay using primers flanking the deleted region of chloroplast DNA, revealing that the same 241 bp was deleted at the same position in these accessions.

The potato in Spain during the late 16th century

A study is presented of the Hospital de la Sangre account books in Seville at the Archivo Hispalense for the period 1546 to 1601, to verify purchases of potatoes (Solanum tuberosum) during that…
