Abstract
  1. Contributions to the origin of cultivated rice made by the author and his colleagues were briefly reviewed under several headlines.-2) Two parallel series of evolution of cultivated species, the Asian form of Oryza perennis to O. sativa and O. breviligulata to O. glaberrima, were pointed out compared.-3) In both the two series, a continuous array of intergrades between wild and cultivated species is found in a particular region. The pattern of character variations among those intermediate plants was considered as indicating the evolutionary path, and the monophyletic origin of the Indica and Japonica types of O. sativa was discussed.-4) The conditions of establishment of a weedy form of O. perennis found in India were discussed. It was noticed that cultivation by man in itself works as a selective agent for cultivated types.
摘要
  1. 作者及其同事对栽培稻起源的贡献,简要地从几个方面加以综述。

  2. 比较了两个平行的栽培种进化系列,即多年生亚洲普通稻到栽培稻和短舌野生稻到光稃野稻。

  3. 在这两个系列中,在一个特定的地区,在野生种和栽培种之间存在着连续的中间类型系列。这些中间类型植物的性状变异模式被认为表明了进化途径,并且讨论了栽培稻籼稻和粳稻类型的单系起源。

  4. 讨论了在印度发现的普通稻杂草形式建立的条件。人们注意到,人类的栽培本身就是栽培类型的选择因素。
