| 摘 要： | 用人工接种方法共鉴定了206份玉米品系雄穗的抗螟性。在田间条件下发现幼龄幼虫的矫正存活率B_(73)为30％;SD_(37)为51.2％和FR_(140)为66.7％。发现取食FR_(140)雄穗的幼龄幼虫体重最轻,平均为1.20mg(感虫对照为2.05mg)。本结果可作为进一步研究雄穗抗螟性的参考。

| Abstract: | Tassel of 203 maize strains were e/aluatel for resistance to Asian coin borer using artificial infestation technique. Under the field con- dition, corrective survival rate of young larvae were 30% on B_(73), 51.2% on SD_(37) and 66.7% on FR_(143), and lowest mean larval weight of 1. 20mg was found on FR_(141). These strains may be used as materials for future resistance studies. |
