The occurrence of races among 65 Australian isolates of Pseudornonas syringae pv. pisi, the causal organism of bacterial blight of field peas, was investigated. Race 3 was most common in Victoria and New South Wales, while race 6 was most common in South Australia. Field pea cultivars were screened for their resistance or susceptibility toward the 7 races of P. syringae pv. pisi. The most common cultivars were susceptible to races 3 and 6, explaining the high incidence of these races in this survey. All cultivars tested were susceptible to race 6, which was identified in all 3 States. |
