| 摘 要： | 对海禾、铁单、屯玉系列一些品种进行研究,界定玉米灰斑病对沈阳地区主栽玉米品种的产量损失。结果表明,供试品种灰斑病害级别为1级、3级和5级;导致玉米减产10%～50%,屯玉13和屯玉38损失达40%～50%;玉米灰斑病对玉米百粒重、穗长和行粒数等产量特征有明显影响,对玉米穗行数没有明显影响。

| Abstract: | In order to determine the loss rate of corn caused by the disease,we studied on the series varieties including Haihe series,Tiedan series and Tunyu series.The results showed that the scales of gray leaf spot on maize by artificial inoculation were 1,3 and 5 rank.The yield loss on the disease changed from 10% to 50%,the severity could reach to 40%-50% on Tunyu 13 and Tunyu 38.The yield characters,which were the 100-grain weight and the ear length and the grains per row in ear,decreased with the scale increased,there were no significant effect of gray leaf spot to and the ear row. |
