本文对花粉不育、自交不亲和性、性别遗传的特殊形式以及花器变形导致的雌性化等不同遗传机制进行了讨论.它们在杂交种育种中应用的优缺点取决于机制本身,也取决于生产杂交种的物种.在生产杂交种中最重要的遗传机制是胞质雄性不育.分子水平上的研究可望能够对在杂交种生产中具有重要作用的机制的遗传基础做更深入的了解.
In this paper, different genetic mechanisms such as pollen sterility, self-incompatibility, gender-specific inheritance and feminization caused by flower deformation are discussed.The advantages and disadvantages of their application in hybrid breeding depend on the mechanism itself and also on In the production of hybrid species. The most important genetic mechanism in the production of hybrids is cytoplasmic male sterility. Studies at the molecular level are expected to provide further insight into the genetic basis of mechanisms that play an important role in the production of hybrids To understanding.
