Quantifying the Effect of Salinity Stress on Different Genotypes of Quinoa and Amaranth Compared to Barley, Pearl Millet, Sorghum and Finger Millet in Hydroponic System

A wide range of short-term hydroponic experiments are conducted in the greenhouse  (1). The current experiments are focused on:

1. Comparing the salinity tolerance of quinoa (Chenopodium quinoa) and amaranth (Amaranthus sp.) accessions with that of barley (Hordeum vulgare), pearl millet and sorghum; as well as the relative salinity tolerance of quinoa with that of amaranth;
2. Evaluating physiological parameters in different accessions at increasing salinity levels;
3. Determining the range for the level of tolerance to salinity within the crops;
4. Comparing the salinity tolerance of quinoa accessions in the diversity panel at the germination and early seedling stages;
5. Comparing salinity tolerance in a mini-core collection of sorghum;
6. Comparing salinity tolerance in a mini-core collection of finger millet.
