在接种有赤星病菌(Alternaria alternata)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了离体抗病性鉴定,结果表明:其中70％的植株不同程度地表现赤星病抗性,部分表现高度抗性。
Mutant seedlings were successfully induced from anthers of the highly susceptible A. tabaci NC89 antisera on bilayer culture medium inoculated with Alternaria alternata and the in vitro resistance of these mutant seedlings was identified and the results The results showed that 70% of the plants showed some degree of brown spot resistance and some showed high resistance.
