Summary
Accessions ofM. tricuspidata (L.) R. Br.,M. aspera Boiss. andMatthiola longipetala (Vent.) DC. were tested for their reaction to bacterial blight of stock (M. incana R. Br.), caused byXanthomonas 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 ofM. incana were severely infected. InterspecificF 1 hybrid plants betweenM. incana andM. tricuspidata also exhibited high resistance to the disease. The implications and the expected difficulties in breeding stock for bacterial blight resistance are discussed.
