The origin of millet from Neolithic China has generally been accepted, but it remains unknown whether common millet (Panicum miliaceum) or foxtail millet (Setaria italica) was the first species domesticated. Nor do we know the timing of their domestication and their routes of dispersal. Here, we report the discovery of husk phytoliths and biomolecular components identifiable solely as common millet from newly excavated storage pits at the Neolithic Cishan site, China, dated to between ca. 10,300 and ca. 8,700 calibrated years before present (cal yr BP). After ca. 8,700 cal yr BP, the grain crops began to contain a small quantity of foxtail millet. Our research reveals that the common millet was the earliest dry farming crop in East Asia, which is probably attributed to its excellent resistance to drought.
粟源自中国新石器时代这一观点已被普遍接受,但目前仍不清楚是黍(Panicum miliaceum)还是粟(Setaria italica)是最早被驯化的物种。我们也不知道它们的驯化时间和传播路线。在此,我们报告在中国新石器时代磁山遗址新发掘的储存窖穴中发现了仅可鉴定为黍的颖壳植硅体和生物分子成分,其年代可追溯至距今约10300至约8700校正年(cal yr BP)。在距今约8700 cal yr BP之后,谷物作物开始含有少量粟。我们的研究表明,黍是东亚最早的旱作作物,这可能归因于其出色的抗旱性。
