Using a systems approach to investigate the efficacy of a disease rating system for Sclerotinia stem rot in canola

| description | Sclerotinia stem rot (SSR), caused by the necrotrophic fungus Sclerotinia sclerotiorum, is a major, but
unpredictable disease of canola in Australia. However, there is no disease rating system for current
canola varieties. Over the last four years the most common varieties of canola grown in Western
Australia were assessed in the field using natural disease occurrence, and in glasshouse experiments
using manual inoculations, to determine their susceptibility to SSR. The results highlighted the
complexity and unpredictable nature of SSR with infection levels and varietal response varying
depending on seasonal conditions and time of infection, despite limited levels of genetic resistance to
SSR in current varieties. It is suggested that a disease rating system should not be based purely on inseason plant infection, but should also include potential for future infections through the contribution
of sclerotia from infected plants to the system. |
