| 摘 要： | 两用核不育水稻的育性受光周期和温度的调控,光温之间还存在互作效应,从生理、遗传角度可解释这种现象。遗传背景、育性指标的不同,研究方法的局限性以及两用核不育水稻的基本特性导致了遗传研究的复杂性。在育性转换过程中,一些生理生化物质会发生相应变化,并与育性相关。本文还从生态、遗传角度讨论了能否用粳稻中的不育基因转育成典型籼稻光敏不育系的问题,并就如何提高不育系稳定性问题进行了讨论,认为利用人工辅助法来提高稳定性是目前值得深入探讨的问题。

| Abstract: | The fertility of double-functional genic male-sterile rice was controlled by photoperiod and tem- perature;the interaction between photoperiod and temperature was common,which may be explained from the view of physiology and genetics.Owing to the difference of genetic backgrounds and fertility indicators, the limitation of research methods and basic characteristices of double-functional genic male-sterile rice,dif- ferent results were deduced in genetic resea ches.Some physiological and biochemical substanc... |
