Chenopodium album is one of the more common Chenopods in Eurasia. It's considered as a weed in Europe but there are some studies that confirm its domestication in the Himalayas. This species, very diverse and unknown (2x, 4x and 6x), was cultivated in China, India, Nepal and Bhutan. But today it's very difficult to know the real superficie covered by C album as a crop. Where are the farmers, in which agroecological conditions, for what kind of uses (grains, leaves, etc.)?
One reason for the lack of documented information on chenopods is that many past reports misidentified Chenopodium album as a variety of Amaranth (Amaranthus anardana).
