| 摘要: |
| 本文讨论了雄性不育系在自由异花授粉条件下的生物学意义。我们认为雄性不育性既不是畸形也不是病态现象,而是生物在进化过程中的一种适应性的反应。因为无论是雄性或雌性性器官的退化,都会迫使生物不得不进行异花授粉,从而增强有效地利用自然条件的本领。为此,育种者应充分利用不育系在异花授粉条件下形成的适应性。 |

| Abstract: |
| This paper discusses the biologic signification of open-cross-pollin- ation,wheat is a model self pollinated plant.Hybrid wheat is regarded as aPressure systemof organism which is new produced ueder the control of person.So that,we should consider that male sterility is not monstrosity and metamorphosis,but an adaptation of evolution,because the inevolution of the reproduction organ,whether male or female,does not bring about any fatal influence to an organ- ism.On the contrary,that will make the organism m... |
