- 摘要:
- 为明确品种抗病性差异，利用田间接种法，对24个玉米品种田间接种大斑病，并进行品种抗性分析。结果表明：不同品种对大斑病抗性存在一定的差异，24个品种中早熟品种14个，其中4个品种对大斑病表现为感病（S）；中熟品种5个，全部表现为抗病（R）和中抗（MR）；晚熟品种5个，其中2个品种对大斑病表现为感病（S）。
- Abstract:
- In order to ascertain the resistance difference of variety diseases,taking 24 varieties of maize as materials,resistances between varieties were analyzed by field inoculation of leaf blight.The results showed that different varieties had different resistance.4 varieties of 14 tested early maturing varieties were susceptible(S);Five middle maturing varieties were resistance(R)and middle resistance(MR);Five late maturing varities,two were susceptible(S).
