Abstract:: During 1992- 1995, 3391 cultiva rs and 169 wild soy bean accessio ns f rom di fferentprovinces w ere ev alua ted for their resistance to race 5 of so ybean cyst nematode by na turalinfection in the field and po t culture w ith infected soil of race 5 of soy bean cyst nematode.Among the g ermplasms ev aluated 27 accessions showed resi stant, it was 0. 80%o f the to tal ev aluatio n number of cultiv ars. These resistant v ari ties w ere almost black inseed colo r. Amo ng the g ermplasms evaluated 3 accessio ns show ed resi stant, i t w as 1.78% of the to tal ev alua tion number o f wi ld so ybean. There w as no immune accessio nsin bo th w ild so ybeans and cul tiv ars. Most of accessions resi stant to so ybean cy st nematodecame f rom Hebei , Sha ndo ng , Shanx i, Chifeng , Jilin and Heilo ng jiang.
