Andean tuber bean ( Pachyrhizus ahipa )
|( Wedd. ) Parodi|
The Andean tuber bean has its origin in the mountainous South America (from the Andes the common German name ), where it was used by the Inca . It thrives at altitudes from 1000 to over 2500 meters and therefore at moderate temperatures. The tubers are mainly eaten, but although they are poisonous, the pods and seeds are also used. Today it is seldom grown.
Pachyrhizus ahipa is a perennial , upright to semi-upright and herbaceous plant that reaches heights of 40 to 60 centimeters, twisting forms are up to about 0.6-2 meters long or high. Unlike the rest of the species in the genus, it is not a climbing plant. They form radish-shaped tubers up to 15 centimeters long as persistence organs and as water reservoirs. However, it is grown as an annual plant because the whole plant is harvested because of the tubers and re-sowing is necessary in the following year. The small, regularly shaped tuber has a yellowish skin, white, fiber-streaked “meat” and weighs between 500 and 800 g.
An approximately 8 to 17 cm long, slightly constricted and briefly tipped legume is formed, which contains red-brown to black or white-black, round, somewhat flattened and smooth seeds with a diameter of about 1 cm.
Oil can be obtained from the seeds.
