Screening methods of resistance to bacterial wilt caused by Pseudomonas solanacearum in tomato and its application in tomato breeding

Three screening methods were used to identify the resistances of 9 tomato lines to bacterial wilt(Pseudomonas solanacearum E.F.Smith).The results of this study showed that there were significant differences among the 9 lines,in which lines of 85198 and 203 were susceptible to bacterial wilt,whereas lines of 47254,51255,7585,and 85254 showed resistance to bacterial wilt.According to the characters of the three methods,proposed resistant evaluation system was used to develop the resistant varieties of tomato.
