Abstract:
Accessions of M. tricuspidata (L.) R. Br., M. aspera Boiss. and Matthiola longipetala (Vent.) DC. were tested for their reaction to bacterial blight of stock (M. incana R. Br.), caused by Xanthomonas campestris pv. incanae. Potted plants were sprayed with bacterial cell suspension, adjusted to 108 cells/ml. The tested accessions of the three species were found highly resistant, while control plants of M. incana were severely infected. Interspecific F1 hybrid plants between M. incana and M. tricuspidata also exhibited high resistance to the disease. The implications and the expected difficulties in breeding stock for bacterial blight resistance are discussed. © 1995 Kluwer Academic Publishers.
