In Brazil, the center of cassava origin, cassava landraces have acquired through their domestication a large diversity in relation to many economic traits such as high content of carotenoids and excellent palatability among other characters. One of these clones, which has been grown by indigenous Brazilian farmers and is now being maintained in the University of Brasília gene bank, showed a high level of lycopene content (5 mg/kg viz. a viz. zero in common cultivars, and 12-20 mg/kg in tomato, a lycopene-rich vegetable). A second landrace called UnB 400 had a high content of beta-carotene, which reached 4 mg/kg.
在木薯的起源中心巴西，木薯地方品种在驯化过程中，在许多经济性状方面获得了丰富的多样性，比如类胡萝卜素含量高、适口性极佳等。其中一个克隆品种，一直由巴西本土农民种植，目前保存在巴西利亚大学基因库中，其番茄红素含量很高（5毫克/千克，而常见品种为零，富含番茄红素的蔬菜番茄的含量为12 - 20毫克/千克）。另一个名为UnB 400的地方品种β-胡萝卜素含量很高，达到了4毫克/千克。
