Eight cassava (Manihot esculenta Crantz) cultivars, of which four are indigenous to the Amazon region, along with an interspecific hybrid, were assessed for their carotenoid content. They were propagated and are maintained in the living Manihot collection at the University of Brasília. The cultivar "Amarelinha do Amapá", which was collected from the State of Amapá, was found to have a very high content of beta-carotene: 27 mg per 100 mg, which is more than 50-fold higher than in other cassava cultivars. This cultivar, which also has excellent palatability, could be an important source of beta-carotene for cassava breeding.
对八个木薯（Manihot esculenta Crantz）品种以及一个种间杂交品种进行了类胡萝卜素含量评估，其中四个品种原产于亚马逊地区。它们在巴西利亚大学的木薯活体收集中进行繁殖和保存。从阿马帕州收集的“阿马帕黄”品种被发现含有非常高的β-胡萝卜素：每100毫克含27毫克，比其他木薯品种高出50多倍。这个品种的口感也非常好，可能成为木薯育种中β-胡萝卜素的重要来源。
