杂种优势理论研究的回顾与展望

Review and prospects of studies on heterosis theory

杂种优势是生物界的普遍现象，目前，其遗传理论的发展远落后实践中所取得的成就，这就限制了杂种优势的进一步利用和预测。本文在论述杂种优势遗传理论研究现状的基础上。

The hetrosis exists generally in the world of living things, but the deve lopment of its genetic theory lags far behind the achievements in practice for the moment, which restricts the further utilization and prediction of heterosis. On the basis of elucidating the research on the heterosis therory, the prospects of future development also was reviewed.
