Quinoas of this region are small with a short vegetative period because of the environmental conditions (only two rainy months), and show morphological, physiological, anatomical, biochemical and phenological modifications to withstand drought stress (Mujica et al., 2010c). They grow in areas above 3900 m with an annual rainfall of 150–350 mm. Plants have small leaves, nyctinastic movements according to daylight hours, various colours, high betacyanin and calcium oxalate content, and a deep and highly branched roots structure. The leaves and inflorescences are used as food. They produce small to medium grains, and have high saponin content. They are planted as a sole crop, generally as mixtures of local varieties. The cultivation technology under these rainfall conditions uses more seed for planting. Farmers usually plant this quinoa with camelid and sheep manure. Seeds are sown just after the first rain in these areas in Peru and at the end of winter in dry conditions in Chile. Under certain conditions roots and stems are used for llipta or llucta (preparation of the pungent ashes of the quinoa).

These quinoas are also called ‘quinua’ with variety names such as Antahuara, Ucha, Ccoyto, Roja Ayauchana. They are located in Condoriri, Puno; Cangallo, Ayacucho; Acobamba, Huancavelica in Peru; Colchane and San Pedro de Atacama in Chile; Pisiga Choque in Bolivia.
