Disease management
- Resistant (R) to anthracnose, similar to PBA Barlock and Tanjil. Seed dressings are still recommended to reduce the risk of seed borne infections.
- Resistant (R) to phomopsis stem blight, similar to PBA Gunyidi, Coromup and Mandelup.
- Resistant (R) to grey spot, equivalent to PBA Barlock.
- Moderately susceptible (MS) to brown spot. Current best practices for disease management should be followed.
Virus
- Moderately resistant (MR) to Cucumber Mosaic Virus (CMV) seed transmission, equivalent to PBA Gunyidi and Mandelup.
- Moderately resistant (MR) to Bean Yellow Mosaic Virus (BYMV) and Black Pod Syndrome (late infection BYMV), similar to Jenabillup, and better than PBA Barlock.

Agronomy
Agronomic characteristics
- PBA Jurien has similar agronomic characteristics when compared to PBA Gunyidi, with flowering time slightly earlier than PBA Barlock and similar to PBA Gunyidi, Coromup and Mandelup.
- PBA Jurien is taller than PBA Barlock and PBA Gunyidi, similar to Mandelup and Coromup.
- PBA Jurien is moderately susceptible (MS) to lodging in high rainfall regions, equivalent to Mandelup.
Herbicide tolerance
- PBA Jurien shows equivalent tolerance to registered herbicides for lupins including metribuzin as Coromup, with greater tolerance than Mandelup.
Harvestability
- Harvest height is similar to Mandelup, and is higher than PBA Barlock and PBA Gunyidi.
- Harvest grain loss risk is similar to that of PBA Gunyidi, PBA Jurien is less resistant to pod shattering than PBA Barlock, but not as susceptible as Mandelup.
- PBA Jurien has slightly higher risk of lodging in high yielding situations than PBA Barlock.
Grain Quality
PBA Jurien has medium to large seed, similar to Mandelup and the alkaloid content is similar to PBA Gunyidi. Alkaloid contents fluctuate between years, sites and varying seasonal conditions.
