利用27对SSR标记对云南普通野生稻的2个自然群体进行遗传多样性和起源进化分析,结果发现我国其他省份的材料与东南亚材料的遗传多样性较高,云南元江材料的遗传多样性最低。亲缘关系分析结果表明,云南元江材料与我国其他省份的普通野生稻之间关系较近,云南景洪普通野生稻与缅甸的普通野生稻关系最近,且云南元江和景洪的普通野生稻的遗传结构之间存在明显差异,说明云南普通野生稻属于中国与东南亚普通野生稻的过渡类型,为水稻起源地的“印度阿萨姆——中国云南”学说提供了科学依据。
Genetic diversity and origin evolution analysis of two natural populations of O. japonica from 27 pairs of SSR markers showed that the genetic diversity of the materials from other provinces in China was higher than those from Southeast Asia, and the genetic diversity of Yunnan Province was the lowest. Phylogenetic analysis showed that there was a close relationship between Yunnan Yuanjiang material and common wild rice in other provinces of China. Yunnan Jinghong common wild rice had the closest relationship with Burmese common wild rice, and the inheritance of common wild rice in Yuanjiang and Jinghong of Yunnan There was a significant difference between the two genotypes, indicating that Yunnan common wild rice belongs to the transitional genus of common wild rice between China and Southeast Asia, providing a scientific basis for the “Indian Assam-China Yunnan” theory of rice origin.
