    Abstract:

    Identification of resistance of Brassica campestris L. ssp. chinensis germplasm resources to Plutella xylostella was conducted by artificial inoculation in the greenhouse. The result showed that pest index ranged between 18.10- 100.00 accessions resistance were significantly different and classified into six, corresponding HR, R,MR,MS, S, HS. Among them, six accessions behaved highly resistant and eleven resistant to Plutella xylostella. The result also indicated that the resistance of materials to Plutella xylostella was significantly related to crinkle of leaf surface. Smooth leaf surface accessions was most potential for selecting resistant materials.
