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.
Mutant seedlings were successfully induced from anther of the highly susceptible A. tabaci NC89 antisera on a two-layer medium inoculated with A. solani. In vitro disease resistance identification of these mutant seedlings showed that 70% of the plants were different To some extent, it showed resistance to brown spot disease and partly showed high resistance.
