| 摘 要： | 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。

| Abstract: | Objective] This study was conducted to identify the thermo-sensitivity of the male sterile line （NYB） of Ningxia hot pepper. Method] The pol en abortion rates of pepper male sterile line under artificial y control ed temperature condition and nature temperature condition were measured and compared. Result] The pol en abortion was the sign of NYB male sterility. The pol en abortion rate changed little under different temperature conditions, while pol en amount greatly reduced at low temperature, indicating that NYB was genetical y stable in field. Conclusion] The re-sults can provide some theoretical references for the application of NYB pepper male sterile line in breeding work. |
