摘要
为了在生产上广泛推广玉米杂交种,以新引入的63份玉米自交系为材料,采用人工接种方法进行玉米自交系抗丝黑穗病鉴定。结果表明:供试材料对玉米丝黑穗病抗性差异较大,其中表现高抗的自交系3份;抗病的自交系7份;中抗的自交系14份;感病的自交系32份;高感的自交系7份。
In order to widely popularize maize hybrid in the production,taking sixty-three new introduced inbred lines as materials,their head smut resistance was evaluated by artificial inoculation.The results showed that there was a large difference of resistance to head smut.There were three inbred lines with high resistance,seven inbred lines with resistance,fourteen inbred lines with middle resistant;thirty-two susceptible inbred lines and seven high susceptible inbred lines.
