摘要
文章列举了野生植物与栽培植物表型的一些主要区别，着重讨论栽培植物起源的遗传基础，并根据观察和试验，论证了自然界中通过杂交与多倍体化形成新的栽培植物的可能性．
The paper cited several chief differences between wild plant and cultivated plant,biscuit hereditary basis of the origin of cultivated plant. According to the, observations and tests,it demonstrated the possibility of formation the new cultivated plant in nature through hybridization and polyploidization.
