杂种优势是广泛存在的遗传学现象,并在多种动植物中得到成功的利用,但对于杂种优势产生的遗传学机理尚未十分清楚.本文对植物杂种优势机理研究进行了较为详尽地评述,在综述了杂种优势遗传基础经典理论和假说的基础上,概括了利用分子生物学手段解释杂种优势遗传基础的一些新见解.探讨了杂种优势群和分子标记与杂种优势的关系.最后对杂种优势研究的未来发展方向进行了展望.

Heterosis would be a well known genetic phenomenon in the fields of biology,which has been successfully exploited on breeding of many plants and animals, but the genetic basis of heterosis might still remain uncertainly puzzles by far. In this paper,the mechanisms of heterosis were reviewed, some new opinions about genetic basis of heterosis were summed up on the base of the classical theories and hypothesis on the genetic mechanisms of heterosis. Discuss the relationship of the heterosis between heterosis group and molecular mark. Finally this paper has looked forward to the direction of heterosis.
