[Identification of AFLP markers linked to bacterial wilt resistance gene in tomato].

A cross between bacterial wilt resistant tomato variety "T51A"and susceptible variety 'T9230' was made for mapping bacterial wilt resistance gene(s). Through inoculation test of its F1 and F2 progeny, it was proved that the resistance of 'T51A' to bacterial wilt was controlled by one heterozygous gene and cytoplasm. With 64 EcoR I/Muse I primer combinations, AFLP analysis was performed on two parents and their F2 resistant and susceptible bulks.
