普通野生稻一直被认为是亚洲栽培稻的野生祖先,也是水稻改良过程中的重要种质资源。普通野生稻经过近万年的驯化到农家品种,进一步经过近百年的现代育种得到现代栽培稻品种,这一过程伴随着遗传多样性的减少和很多优异基因的丢失。育种家在现代育种实践中也逐渐意识到这一点,水稻重大改良过程中的很多重要基因,如袁隆平

Common wild rice has long been considered the wild ancestor of Asian cultivated rice and is also an important germplasm for rice improvement. After nearly ten years of common wild rice domestication to the farm variety, further modern varieties of modern rice breeding through nearly a century of modern, with the reduction of genetic diversity and many excellent gene loss. Breeders have also gradually realized this in modern breeding practices. Many important genes in the process of major improvement of rice, such as Yuan Longping
