Abstract:: 　 Fifty-seven soybean accessions were tested for resistance to cotton worm (Prodenia litura Fab-ricius)by feeding test .Larval weight at 10 days was used as index for resistance .According to the resultsobtained in 2001 and 2002 , there existed significant differences in the resistance of soybean among the 57accessions and between two years, and there existed also significant interactions between soybean acces-sions and years.Four materials were identified to be highly resistant to cotton worm , while there were i-dentified to be highly susceptible to cotton worm .These genotypes will be used as standard variety for re-sistance identification and as materials for novel resistance genes’discovery .
