摘要
连续2年对毕节地区主栽杂交玉米品种,在人工接种条件下进行丝黑穗病的抗性试验。结果表明,品种间抗性存在明显差异。10个参试品种中,毕单10号、临奥4号、海禾1号为高抗品种,毕玉2号、毕单4号、毕玉4号、贵毕302、黔西4号为中抗品种,贵毕301、安单136为高感品种。
The fungus threads of head smut were inoculated on the main hybrid maize varieties to evaluate its resistant ability. The results indicate that there is significant difference in resistant ability among ten tested varieties and the varieties with strong resistant ability are Bidan 10, Lin-ao 4 and Haihc 1, the varieties with middle resistant ability are Biyu 2, Bidan 4, Biyu 4, Guibi 302 and Qianxi 4 and the highly susceptible varieties are Guibi 301 and Andan 136.
