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

Chenopodium hircinum, the putative wild ancestor of quinoa, is a source of traits that could improve the tolerance of crop quinoa to high temperatures. However, seeds of C. hircinum have physiological dormancy (PD), which is an obstacle for plant propagation and use in breeding programs. We studied the intraspecific variability in morpho-anatomical...
Genotype × environment (GxE) interaction effects are one of the major challenges in identifying cultivars with stable performance across agri-environments. In this study we analysed GE interactions to identify quinoa (Chenopodium quinoa) cultivars with high and stable yields under different soil moisture regimes, representing control conditions, wa...
Intraspecific variation in plant traits, such as leaf morphology, offers insights into local adaptation and the ecological niche breadth of species. Chenopodium hircinum, the wild ancestor of quinoa, is widely distributed across various ecoregions in Argentina. A detailed comparative analysis of leaf morphology across 23 populations covering its en...

Cotton is often exposed to high temperatures during the reproductive stage, which can negatively affect its productivity. The objectives were to: i) test whether heat stress impacts during the reproductive stage on photosynthesis are due to instant temperature effects or to acclimation produced during the heat stress period, ii) evaluate the role o...
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...
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...
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...
