[目的]探讨宁夏羊角椒雄性不育系的温敏性。[方法]通过人工控温诱导试验与田间自然温度生长试验调查宁夏羊角椒在不同温度条件下的花粉败育率。[结果]NYB的雄性不育表现为花粉的败育,虽然花粉量受低温影响较大,但花粉的败育率基本没有明显变化,田间生长不育性稳定。[结论]该研究为NYB辣椒雄性不育株系在育种工作中的应用奠定基础。
[Objective] The research aimed to discuss the temperature sensitivity of Ningxia pepper male sterile line. [Method] The pollen abortion rate of Ningxia Yangjiaojiao at different temperatures was investigated by artificial temperature-control induction experiment and field natural temperature growth experiment. [Result] The male sterility of NYB showed the abortion of pollen. Although the amount of pollen was greatly affected by the low temperature, the abortion rate of pollen did not change obviously and the growth and sterility in the field was stable. [Conclusion] This study laid the foundation for the application of NYB Pepper male sterile line in breeding.
