Lessons For On-Farm Conservation Of Djulis Diversity In Taiwan: I. An Ethnobotanical Survey Of Chenopodium formosanum.

Djulis, Chenopodium formosanum, the Taiwan Austronesian cultivated chenopod, is recognized as a nutrient-rich ‘ruby’ cereal and is the only chenopod in the same league as quinoa, C. quinoa. Because of its high nutritional values, medicinal effects, health benefits, high crop yields, colorful fruits, and great adaptability, djulis––especially the red-fruit landraces––has been greatly promoted since the late 1990s, and its production and prices have accelerated dramatically. However, the vanishing of other djulis landraces and the loss of relevant indigenous cultures has completely been ignored. The on-farm conservation is urgent and demanded for djulis diversity as well as for indigenous cultures.  In present study, we conducted a comprehensive ethnobotanical survey in Taiwan focusing on the djulis landraces left and relevant cultures. In total, we visited 426 Taiwan Austronesian and Han djulis farmers and acquired 1,016 djulis collections. Our data show that djulis is mainly grown in southern and eastern Taiwan. Most of djulis farmers are from Austronesian tribes (93%). Most djulis farmers are female (72%), which highlights the important role of females in the indigenous agriculture and landrace conservation. Unfortunately, the farmers obtained most of their djulis (91%) from seed companies or governmental agriculture departments. Only 8% of the studied djulis are originally owned by the farmers or his/her families. In sum, our study provides an overview of current situation for djulis. This information will facilitate further planning on-farm conservation of djulis diversity.*This study was supported by the Forestry Bureau in Taiwan (108C019) and Ministry of Education in Taiwan (Higher Education Sprout Project).
