Thirty three Brassica materials including four Brassica junceaCoss.var. megarrhiza Tsen et Lee,one B. juncea var. crassicaulis Chen et Yang,three B. juncea var. tumidaTsen et Lee,six Brassica juncea var. multicepsTsen et Lee, eleven Brassica juncea var. rugosa Bailey,two Brassica junceavar.capitata Hort,one Brassica juncea var. longepetiolata Yang et Chen,one Brassica junceaCoss.var. gracilis Tsen et Lee,four Brassica juncea var.latipa Li were inoculated with TuMV isolate.Through disease investigation and convulsion ELISA ,nine mustard materials were found to be TuMVresistant,laying the foundation for disease resistance breeding.The condition indexes of both of the numbers 17Y7V and 17Y36V in disease investigation were 0, showing immunity.Its DP/DN ratio of the ELISA test were less than 2.1, which were 1.38 and 1.97,showing negative performance.The condition index of the numbers 17Y13V, 17Y20V, 17Y21V, 17Y31V, 17Y33V, 17Y34V, and 17Y35V in disease investigation were 2.86, 5.33, 2.00, 8.00, 5.93, 5.71, 2.00, showing high resistance. Its DP/DN ratio of the ELISA test were less than 2.1, which were 1.12, 0.89, 1.60, 0.93, 0.78, 0.81, and 1.33, showing negative performance.
