摘  要:
杂种优势是农业生产中非常重要的遗传现象之一。杂种优势虽然已经被成功应用了数个世纪,但其形成的机理仍不十分明了。不同时期的学者在不同层次上进行了大量的研究和探索并相应地提出了一些解释或假说,但至今都没有形成一个较为一致的解释。本文综述了作物杂种优势机理相关的重要假说以及近年来国内外的相关研究进展。

摘  要:
As an important genetic phenomenon in organic sphere,heterosis(or hybrid vigor) has been successfully utilized for centuries.Though lots of work have been done by researchers worldwide,the genetic basis underlying heterosis remains unclear.In this paper,we summarized some important hypotheses related to heterosis,and the recent advances in the studies of heterosis were also discussed.
