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)。
In order to ascertain the resistance difference of variety diseases, taking 24 varieties of maize as mate- rials, resistances between varieties were analyzed by field inoculation of leaf blight. The results showed that dif- ferent 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 rarities, two were susceptible（S）.
