abstract = {Quinoa (Chenopodium quinoa Willd.) is a genetically diverse
crop that has gained popularity in recent years due to its
high nutritional content and ability to tolerate abiotic
stresses such as salinity and drought. Varieties from the
coastal lowland ecotype are of particular interest due to
their insensitivity to photoperiod and their potential to be
cultivated in higher latitudes. We performed a field
experiment in the southern Atacama Desert in Chile to
investigate the responses to reduced irrigation of nine
previously selected coastal lowland self-pollinated (CLS)
lines and the commercial cultivar Regalona. We found that
several lines exhibited a yield and seed size superior to
Regalona, also under reduced irrigation. Plant productivity
data were analyzed together with morphological and
physiological traits measured at the visible inflorescence
stage to estimate the contribution of these traits to
differences between the CLS lines and Regalona under full
and reduced irrigation. We applied proximal sensing methods
and found that thermal imaging provided a promising means to
estimate variation in plant water use relating to yield,
whereas hyperspectral imaging separated lines in a different
way, potentially related to photosynthesis as well as water
use.},
