PBA Barlock - an anthracnose resistant, metribuzin tolerant narrow-leafed lupin

Please note: This content may be out of date and is currently under review.

PBA Barlock is a high yielding Australian sweet lupin variety from Pulse Breeding Australia. Suitable as a replacement for Tanjil and Wonga in most lupin growing areas of Western Australia and giving a significant yield improvement in most areas of New South Wales, Victoria and South Australia. It provides a considerable improvement in metribuzin tolerance over Tanjil and Wonga and will allow growers to use metribuzin as an option for controlling weeds within the lupin crop.

Key characteristics of PBA Barlock

  • 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 Tanjil 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 named after ‘Barlock’, one of many indigenous names for the native grass tree, which is widespread on the coastal sands of the west coast of WA.


PBA Barlock (tested as WALAN2325) was bred by Dr Bevan Buirchell, in cooperation with the Department of Agriculture and Food, Western Australia's lupin breeding team under the umbrella of PBA.


From a 2000 cross between 97L122-1 and 89A169-11-11.


  • Similar agronomic characteristics to Tanjil.
  • Slightly later flowering and maturing than Mandelup.
  • Moderately resistant (MR) to lodging in high rainfall regions, equivalent to Tanjil.

Herbicide tolerance

Shows equivalent tolerance to all registered herbicides including metribuzin in comparison to Mandelup.


  • Harvest height is equivalent to Tanjil and is shorter than Mandelup.
  • Harvest grain loss risk is reduced with PBA Barlock being more resistant to pod shattering than Mandelup.
