摘　　要：Rice root-knot nematode(RRKN,Meloidogyne graminicola)and brown spot(BS,Drechslera oryzae)are serious constraints on the quality of rice grains,particularly under direct-seeded rice conditions in many parts of the world.Developing rice varieties resistant to RRKN and BS will be the most effective and environmentally friendly management strategy.A total of 93 and 58 Oryza rufipogon accessions were screened against RRKN and BS,respectively,for two years under artificial inoculation conditions.Among the 93 O.rufipogon accessions。
