Introduction
We are currently working on two research lines: high temperature and waterlogging responses in quinoa. For both subjects we are using the wild quinoa ancestor Chenopodium hircinum from a wide range of environments as potential sources of traits to improve adaptation to these stresses. We are also using mapping populations to screen for the genetic and physiological basis of quinoa high temperature responses

Article
Quinoa cultivation is expanding fast all over the world. The characterization of Chenopodium hircinum populations, its wild ancestor, is highly relevant as they could provide adaptations to new environments. This study evaluated the developmental patterns on populations of C. hircinum, collected from a range of agroecological environments in Argent...

Quinoa’s germplasm evaluation is the first step towards determining its suitability under new environmental conditions. The aim of this study was to introduce suitable germplasm to the lowland areas of the Faisalabad Plain that could then be used to introduce quinoa more effec-tively to that region. A set of 117 quinoa genotypes belonging to the US...

Quinoa has been promoted as a crop for marginal environments. Because of this and high international prices its cultivation was expanded to more than 100 countries in the last decades, and some of these new environments face high temperatures. This is accentuated by temperature increase as a consequence of climate change, making high temperatures a...
Presentation
The aim of this experiment was to understand the physiological basis of genotype by environment by management interaction in quinoa. Experiments were carried out at four environments combining two locations (Valleys and Puna) and two years (2017 and 2019 for Valleys, 2018 and 2019 for Puna). Local genotypes (RQ252 from Valley and RQ420 from Puna) p...

Article
Expansion into areas outside their centers of origin requires knowledge of quinoa’s physiology and its response to the environment concerning the determination of seed yield and its numerical components to facilitate crop management and breeding. The objectives of the current work were to analyze the determination of seed weight (SW) of different q...
Article
Soil moisture stress has become a serious environmental limitation to crop productivity and quality. The root system is the first organ sensing the changes in soil moisture; therefore, root development under water deficit is an important indicator for plant's drought tolerance. Previous studies focused on quinoa varietal differences in morphologica...
Chapter
Quinoa domestication studies based on seed’s morphological traits and conducted in the Central Andes region concluded that it occurred somewhere around Lake Titicaca before 3000 BC. Recent genetic studies showed quinoa (an allotetraploid) resulting from the fusion of two diploid species (carrying the A and B genomes), one Eurasian and one American...

Quinoa cultivation expanded from South America to many countries in the last decades. Most of this expansion was based on trial an error but future breeding and crop management necesitates a better understanding of the crop’s physiology. Even though there were significant advances at the plant and leaf physiological level a crop level of understand...

Soil salinity has become a serious environmental abiotic stress limiting crop productivity and quality. The root system is the first organ sensing the changes in salinity. Root development under elevated salinity is therefore an important indicator for saline tolerance in plants. Previous studies focused on varietal differences in morphological tra...

In the 1970s, during excavations at Los Morrillos, San Juan, Argentina, quinoa seeds were found within ancient pumpkin crocks protected from the light and high temperatures, and preserved in the very dry conditions of the region. The radiocarbon dates confirmed the age of these seeds at around 2300 years. Sectioning of some of these seeds showed re...

Quinoa (Chenopodium quinoa Willd., 2n = 4x = 36) is an Andean broadleaf seed and vegetable crop of ancient origin. Quinoa represents one or two botanical varieties of a much broader tri-species complex native to North and South America and dominated by weedy forms of pitseed goosefoot (C. berlandieri Moq.) and avian goosefoot (C. hircinum Schrad.)....
