Molecular Identification and Analysis of Resistant Gene to Tomato Yellow Leaf Curl Virus
In this paper,239 resistant tomato varieties from ten countries and twenty-seven domestic scientific research institutes and enterprises were collected,and their resistance genes to tomato yellow leaf cud virus were indentified and analyzed by PCR method.The results showed that Ty-1 and Ty-3a resistance genes were now mainly used in the breeding of tomato,which were also mostly used in tomato hybrid with multiple resistance genes to tomato yellow leaf curl virus.
