Abstract:The Chinese cabbage〔Brassica campestris L. ssp. pekinensis(Lour)Olsson〕crosses between TuMV resistant material BP8407 and susceptible material‘Jizaochun’,and between TuMV resistant material‘Erqing’and susceptible material‘Chundajiang’were mechanically inoculated with TuMV-C4 isolate.The joint segregation analysis of P1,P2,F1 and F2 populations derived from these 2 crosses was used to study the inheritance in this paper.Each plant of the 4 populations mentioned above was further examined for its resistance to natural population of Chinese cabbage,according to its ELISA P/N per plant.The results indicated that the resistance was controlled by 2 additive-dominant-epistatic major-gene plus polygene.Major-gene heritability for the 2 crosses are 86.51% and 77.64%,respectively. Therefore,Chinese cabbage’s resistance to TuMV-C4 accords with the 2 major genes plus polygene.The inheritance for TuMV resistance of Chinese cabbage may provide foundation for its mechanism,coarse and fine resistant gene mapping,resistance breeding and marker assisted selection to TuMV.
