摘要

利用在温室中种植的人工侵染植株,对19种玉米抗不同茎秆螟虫品种的抗性进行了评价。经鉴定,抗褐夜蛾(Spodoptera frugiperda, Smith)自交系GT-FAWCC (C5)是抗褐夜蛾高水平食叶的新来源,而抗玉米穗虫(Helicoverpa zea, Boddie)自交系GT115是抗褐夜蛾食穗的新来源。后者是第一个非来自安提瓜第二群背景的fusca B.耐药性记录。

Evaluation of plant resistance to the maize stalk borer, Busseola fusca (Fuller) in maize germplasm improved for resistance to other borer species
Nineteen maize genotypes resistant to various stalk borer species were evaluated for resistance to the maize stalk borer, Busseola fusca (Fuller), using artificially infested plants grown in a greenhouse. The inbred line GT-FAWCC (C5) resistant to the fall armyworm Spodoptera frugiperda (Smith) was identified as a new source of high level leaf feeding resistance to B. fusca, whereas the inbred GT115 resistant to the corn earworm Helicoverpa zea (Boddie) presented a source of resistance to ear feeding by B. fusca. The latter is the first record of resistance to B. fusca not derived from an Antigua Group 2 background.
