- High yielding across most lupin growing areas of WA, NSW, Vic and SA
- Resistant (R) to anthracnose (equal to Tanjil and Wonga)
- Tolerant to metribuzin (superior to Tanjil and equal to Mandelup)
- Improved resistance to pod shattering (equal to TanjilA and Coromup)
- Moderately resistant (MR) to phomopsis stem blight (equal to Tanjil and Wonga)
- Early flowering and early maturity
- Grain quality parameters that on average meet market requirements
PBA Barlock is a high yielding Australian sweet lupin variety suitable as a replacement for Tanjil and Wonga in most lupin growing areas of Western Australia. PBA Barlock provides a very significant yield improvement in most regions of New South Wales, Victoria and South Australia.
PBA Barlock is a considerable improvement in metribuzin tolerance over the varieties Tanjil and Wonga and will allow growers to use metribuzin as an option for controlling weeds within the lupin crop.
Seed protection & royalties
PBA Barlock is protected under Plant Breeder’s Rights (PBR) legislation. Growers can only retain seed from production of PBA Barlock for their own seed use.
An End Point Royalty of $2.75 per tonne (GST inclusive), which includes breeder royalties, applies upon delivery of this variety.
Seed is available from the commercial partner Seednet.
Area of adaptation
Yield & adaptation
PBA Barlock has performed well across most regions and is suggested as a replacement for Mandelup and Tanjil in all lupin growing zones.
PBA Barlock is the best choice in Agzone 1 due to its resistance to anthracnose.
Jenabillup remains the best choice for Agzone 8 due to its Bean Yellow Mosaic Virus (BYMV) resistance (MR).
New South Wales
PBA Barlock has performed significantly better than other varieties in most regions and is suggested as a replacement for
Mandelup and Wonga.
Victoria and South Australia
PBA Barlock provides significantly higher yields on the Upper and Lower Eyre Peninsula and performs well in the Murray mallee.
It is recommended as a replacement for Mandelup in these regions.
- Resistant (R) to anthracnose similar to TanjilA. Seed dressings are still recommended to reduce the risk of seed borne infections.
- Moderately susceptible (MS) to brown spot and the full agronomic package for this disease should be implemented.
- Resistance to phomopsis stem blight is equivalent to Tanjil and Mandelup
- Resistant (R) to grey spot.
- Moderately resistant (MR) to resistant (R) to CMV seed transmission which is better than Mandelup but not as good as Tanjil.
- Moderately susceptible (MS) to late infection of BYMV. Equivalent to Mandelup but not as good as Jenabillup and Quilinock.
- Jenabillup is the preferred variety in WA Agzone 8 to manage the risk from BYMV.
- PBA Barlock has similar agronomic characteristics when compared to Tanjil.
- PBA Barlock is slightly later flowering and maturing than Mandelup. Moderately Resistant (MR) to lodging in high rainfall regions, equivalent to Tanjil.
- PBA Barlock shows equivalent tolerance to all registered herbicides including metribuzin in comparison with Mandelup.
- Harvest height is equivalent to TanjilA and is shorter than Mandelup.
- Harvest grain loss risk is reduced with PBA Barlock being more resistant to pod shattering than Mandelup.

PBA BarlockA has small seed similar to Tanjil. The protein content is similar to Mandelup and the alkaloid content, on average, is similar to Mandelup. The alkaloid content may fluctuate from season to season, but the relative value compared to Mandelup will remain similar.
PBA BarlockA (tested as WALAN2325) was bred by Dr Bevan Buirchell, in cooperation with the Department of Agriculture and Food’s lupin breeding team under the umbrella of Pulse Breeding Australia.
It is from a 2000 cross between 97L122-1 and 89A169-11-11. PBA BarlockA is named after ‘Barlock’, one of many indigenous names for the Native Grass Tree, which is widespread on thecoastal sands of the west coast of Western Australia.
