在育种项目中利用野生近亲的程度取决于作物的野生程度、情况的绝望程度、培育新品种的压力、材料的可获得性、使用的难度以及植物育种者及其工作机构的特点。野生近缘植物已被用作抗病、虫和线虫的来源，以扩大适应范围，提供互换细胞质和发展细胞质不育系统，改善品质，改变繁殖方式，诱导矮小，增加物种间的可交配性，改善抗逆性和增加产量。一些作物如果没有野生近亲的遗传支持，就不能保持商业地位。
The extent of use of wild relatives in breeding programs depends on how wild the crop is, how desperate the situation is, the pressures to turn out new cultivars, the availability of materials, the difficulty of use and the character of the plant breeder and of the institution in which he works. Wild relatives have been used as sources of disease, insect and nematode resistance, to widen adaptation, to provide alternate cytoplasms and develop cytoplasmic sterility systems, to improve quality, alter modes of reproduction, induce short stature, increase crossability between species, improve resistance to stress and increase yield. Some crops can not maintain commercial status without genetic support of wild relatives.
