中文摘要：
利用网室采集的57份大豆资源的叶片，室内喂养刚孵化的斜纹夜蛾幼虫，以幼虫重为指标，鉴定大豆资源对斜纹夜蛾的抗性。综合2001年和2002年的鉴定结果，品种间、年份间、品种与年份互作差异均达极显著水平。根据标准品种分级法对抗性鉴定结果进行划分，从供试的大豆资源中筛选出4个高抗和3个高感的标准品种，可以用于抗性的分级及抗虫新基因的发掘。
英文摘要：
Fifty-seven soybean accessions were tested for resistance to cotton worm （Prodenia litura Fabricius） by feeding test. Larval weight at 10 days was used as index for resistance. According to the results obtained in 2001 and 2002, there existed significant differences in the resistance of soybean among the 57 accessions and between two years, and there existed also significant interactions between soybean accessions and years. Four materials were identified to be highly resistant to cotton worm, while there were identified to be highly susceptible to cotton worm. These genotypes will be used as standard variety for resistance identification and as materials for novel resistance genes＇ discovery.
