[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.展开更多
