摘要： 在接种赤星病菌的双层培养基上，成功地从高感赤星病烟草品种NC89的花药中诱导出突变体苗。对这些突变体苗进行离体抗病性鉴定结果，有70%的植株不同程度地表现出对赤星病抗性，部分表现高度抗性。

Abstract: The mutants were successfully induced from the anthers of tobacco variety NC89 highly sensitive to tobacco brown spot disease by using the double-medium in which Al-ternaria alternata was inoculated. The resistance of these mutants to Alternaria alternata was tested in vitio. The results indicated that 70% of these mutants showed resistance to tobacco brown spot to varying degrees, while some of them were of high resistance.
