摘　　要：研究五大种质常用玉米自交系、自选稳定系及近两年山西省审定的玉米新品种对红蜘蛛抗性的田间调查、鉴定与分析,并建立了对红蜘蛛抗性的分级指标体系。结果表明,5大种质系统抗性有明显的差异,初步认为P系统总体最好;较差的是Reid系统;Lancaster系统、旅大红骨系统、塘四平头系统抗感表现相差不大。证明玉米植株的抗病性、叶片的持绿性、株叶型结构对红蜘蛛抗性有一定的影响。This study were made the field investigation, identification and analysis of 5 commonly used maize inbred lines in china, self-chosen stability lines and new hybrid to maize red spider. The results showed that resistance of five maize heterosis populations to red spider have great differences, P germplasm population was better, reid population was bad, Lancaster and Tangsipingtou and lvdahonggu population were middle. Resistance to diseases and ever green plant characteristic and leaf straight-up type affected resistance to maize red spider.
