Abstract
TuMV is the main virus isolates of virus disease in chinese cabbage, and it has a large effect on the production of chinese cabbage.
Because there is no chemical control on the virus disease, resistant breeding in chinese cabbage becomes nesseary. study of genetics of the disease resistance is essential to breeding this crop.
It was found that the resistance to TuMV was strain specific (R. Provvidenti, 1982). Some person’s study showed that the resistance to TuMV was dominance and governed by two independent genes (Niu Xinke, 1982). The resistance to TuMV was also considered as a quantitative trait.
The resistance to TuMV was partial dominance and additive effect was the main genetic effect controlling the resistance (Tan Qimeng, 1980. S. K. Green, 1986. Lu Yingjie, 1988.). In 1990, AVRDC reported that the resistance to two TuMV strains TuMV-C4 and TuMV-C5 was controlled by two recessive genes.
Due to the difference of materials, virus isolates and methods, the conclusions are not same.
According to the specification of virus disease of chinese cabbage in Beijing, TuMV-C4 strain was used in this experiment to study the genetics of resistance to TuMV in chinese cabbage to give a guidance for the resistant breeding of chinese cabbage in Beijing.
