Quinoa (Chenopodium quinoa Willd.), one of the main crops domesticated in the Andean highlands 1,000 of years ago, played an important role as a protein source. 35 germplasm accessions collected along the Northwest Argentina (NWA) region were studied using 22 microsatellite (SSR) markers. Results showed a great level of genetic diversity, differing from previous reports about the geographical distribution of quinoa variability. All SSR loci analysed were highly polymorphic detecting a total of…

Molecular characterization of Ecuadorian quinoa (Chenopodium quinoa Willd.) diversity: implications for conservation and breeding
TLDR
The results show that ancestral quinoa diversity in Ecuador has prevailed despite the introduction of commercial varieties, and should be preserved for future use in breeding programs.
Molecular characterization of Chenopodium quinoa Willd. using inter-simple sequence repeat (ISSR) markers
TLDR
Molecular Analysis of Variance (AMOVA) and Fst demonstrate the existence of genetic variability at the intraspecific level that should be used in breeding programs of the species lead to obtaining new and better materials of quinua.
Development of novel InDel markers and genetic diversity in Chenopodium quinoa through whole-genome re-sequencing
TLDR
The large number of SNPs and InDels identified in this study demonstrated that the quinoa genome is enriched with genomic variations, demonstrating significant genetic differentiation between the Andean highland type of quinoa and the Chilean coastal type.
Breeding quinoa (Chenopodium quinoa Willd.): potential and perspectives
TLDR
New molecular tools available for the existing quinoa breeding programs, which are critically examined in this review, will enable us to tackle the limitations of allotetraploidy and genetic specificities.
Quinoa (Chenopodium quinoa Willd.) Breeding
TLDR
Current wide distribution and planting in large-scale farms have shown limitations because growth conditions are different from those typical in the origin center, but these can be overcome with new improved varieties using the highly diverse germplasm and appropriate breeding methodology.
Discontinuities in quinoa biodiversity in the dry Andes: An 18-century perspective based on allelic genotyping
TLDR
These processes of local gene pool replacement do not imply losses of genetic diversity at the metapopulation scale, and support the view that gene pool Replacement linked to social and environmental changes can result from opposite agricultural trajectories.

A genetic linkage map of quinoa (Chenopodium quinoa) based on AFLP, RAPD, and SSR markers
TLDR
This map provides a key starting point for genetic dissection of agronomically important characteristics of quinoa, including seed saponin content, grain yield, maturity, and resistance to disease, frost, and drought.
Genetic structure of quinoa (Chenopodium quinoa Willd.) from the Bolivian altiplano as revealed by RAPD markers
TLDR
Randomly amplified polymorphic DNA markers show that quinoa has a strong population structure and a high intra-population variation, and this population structure appears related to three major biogeographic zones: the northern and central altiplano, the interandean valley, and the southern Salar.
Assessment of genetic diversity patterns in Chilean quinoa (Chenopodium quinoa Willd.) germplasm using multiplex fluorescent microsatellite markers
TLDR
The objective of this study was to characterize and quantify the genetic diversity within 28 Altiplano and 31 coastal Chilean accessions of quinoa using microsatellite markers and provides the quinoa scientific community with a new set of easy to use and highly informative genetic markers.
Development and Use of Microsatellite Markers for Germplasm Characterization in Quinoa (Chenopodium quinoa Willd.)
TLDR
These microsatellites markers are an ideal resource for use in managing quinoa germplasm, trait mapping and marker-assisted breeding strategies and the wide cross-species transportability of these markers may extend their value to research involving other Chenopodium species.
Assessment of genetic diversity in the USDA and CIP-FAO international nursery collections of quinoa (Chenopodium quinoa Willd.) using microsatellite markers
TLDR
Heterogeneity was observed in 32% of the quinoa accessions at a given locus and suggests that many of these accessions represent heterogeneous seed lots or landraces and hypotheses regarding quinoa's centre of diversity are discussed, including highland and lowland ecotype clustering patterns.
Simple sequence repeat marker development and genetic mapping in quinoa (Chenopodium quinoa Willd.)
TLDR
The linkage map presented here is the first SSR-based map in quinoa and contains 275 markers, including 200 SSR, and will be particularly valuable for research in laboratories in Andean regions of South America.
Ecogeographic structure of phenotypic diversity in cultivated populations of quinoa from Northwest Argentina
TLDR
A set of 34 quinoa populations from the Northwest Argentina region was characterised using quantitative and qualitative phenotypic traits in an experiment conducted in the province of Jujuy suggesting that individual characterisations offer information that can be complementary.
Analysis of durum wheat germplasm adapted to different climatic conditions.
TLDR
The likelihood relationships among the nine Ethiopian populations indicated that the material collected in the Gonder region was genetically more diverse than the materials from Shewa and Tigray (dryer climates), and the high number of loci in linkage disequilibrium (LD), up to 23, has demonstrated that the loci were associated irrespective of their physical location.
Quinua biosystematics I: Domesticated populations
TLDR
The overall pattern of variation supports the ecotypic approach toward landrace classification of quinua, although congruence between ecological and morphogenetic variation is not complete.
