Long term goal – oilseed crops resistant to the CSPW
A ‘non-host’ for CSPW
Canola x yellow mustardhybrids
cross-pollination between S. alba and B. napus followed by a combination of ovule culture and embryo rescue (Brown et al., 1997)
Glucosinolate Profiles (μmol/g)
Hybrid Glucosinolate Profile
R = ‘Resistant’ to CSPW
= eggs 17% to 25% of control
S = ‘Susceptible’ to CSPW
= eggs 40 to 70% of control
Ross et al. 2003
Canisters for insect choice tests
After 1 day ofoviposition:
dissect under a light microscope
Count feeding punctures and eggs.
