- Highest yielding across all chickpea growing areas of Western Australia and high yields in the low to medium rainfall areas of southern Australia
- Moderately Resistant (MR) to Ascochyta blight (resistance is > Genesis™ 836 but < PBA SlasherA) Improved early vigour compared to PBA Slasher
- Early flowering and maturity (earlier than PBA Slasher and Genesis™ 836)
- Semi spreading plant type (similar to PBA Slasher)
- Medium sized desi seed with excellent milling quality (larger than PBA Slasher and Genesis™ 836)
PBA Striker represents a yield improvement in the short medium to low rainfall environments of western and southern Australia. This is due to its improved early vigour and earlier flowering and maturity compared to PBA Slasher and Genesis™ 836.
It is broadly adapted to these regions and has shown a consistent and significant yield advantage in Western Australia (7-13%) over recently released varieties. PBA Striker has a similar plant type to PBA Slasher with larger seed size than PBA Slasher and Genesis™ 836.
AREA OF ADAPTATION
SEED PROTECTION & ROYALTIES
PBA Striker is protected under Plant Breeder’s Rights (PBR) legislation. Growers can only retain seed from production of PBA Striker for their own seed use.
An End Point Royalty of $4.40 per tonne (GST inclusive), which includes breeder royalties, applies to this variety.
Seed is available from the commercial partner Seednet.
YIELD & ADAPTATION
PBA Striker is currently the highest yielding variety in Western Australia. It is generally well adapted to the medium to low rainfall areas of Western Australia and southern Australia where chickpea is currently or has been previously grown.
Yields of PBA Striker are substantially higher (7-13 %) than PBA Slasher and Genesis™ 836 in Western Australia and similar to PBA Slasher in south eastern Australia.
PBA Striker is not recommended in the higher rainfall regions of south eastern Australia due to its lower resistance to ascochyta blight relative to PBA Slasher.
PBA Striker is not adapted to Northern NSW or Southern QLD as it is susceptible to Phytophthora root rot.

Ascochyta blight (AB)
- PBA Striker is Moderately Resistant (MR) to foliar infection caused by the fungus (Ascochyta rabiei). This resistance is better than Genesis™ 836 but less resistant than Genesis™090 and PBA Slasher.
- AB management for PBA Striker requires seed treatment and at least one fungicide application during the vegetative phase. Monitor the crop 10 – 14 days after each rain event. If AB is detected, apply Unite®or Barrack® (a.i. chlorothalonil) fungicide prior to the next rain event and continue monitoring.
- In WA, an early fungicide application is recommended 6-8 weeks after sowing to delay the development of AB.
- In all regions, monitor crops and apply fungicides from the start of podding prior to rainfall to prevent seed infection.
PBA Striker flowers and pods earlier than PBA Slasher, Genesis™836 and Genesis™090, so an earlier timing of pod sprays will be required.
Botrytis grey mould (BGM)
Controlled environment testing and opportunistic field testing in 2010, indicates that PBA StrikerA is Susceptible (S) to BGM. This rating is similar to PBA SlasherA, Genesis™090 and Genesis™836.
Early sowing coupled with favourable growth conditions in Spring can lead to crops with large biomass increasing the risk of BGM. PBA StrikerA is prone to lodging under these conditions, so consider this when planning an early sown crop.
Apply a preventative fungicide immediately prior to canopy closure in BGM prone areas and continue to monitor in Spring as temperatures and humidity rise. Apply a fungicide containing carbendazim once BGM has been identified.
PBA Striker is rated as Susceptible to the suite of viruses, similar to other desi varieties.

R = resistant, MS = moderately susceptible
# Fortnightly = fortnightly fungicide applications commenced 8 weeks after emergence. All applications were 2 L/ha of chlorothalonil (720 g ai/L)
## Nil = no fungicides applied
### % Yield loss is the yield difference between the fortnightly fungicide treatment and the nil fungicide treatment
Paddock selection and agronomic requirements for growing PBA StrikerA are similar to those for other desi chickpea varieties.
PBA StrikerA has the following characteristics:
- Good early vigour, better than PBA Slasher
- Early flowering, approximately 5-7 days earlier than PBA SlasherA
- Earlier maturing than PBA SlasherA and Genesis™ 836
- Plant height and lowest pod height is similar to PBA SlasherA
- but lower than Genesis™ 836
- Lodging resistance similar to PBA SlasherA
- Semi-spreading plant type similar to PBA SlasherA
- Adapted to a range of row spacing’s and stubble management
- Intolerant of salt, similar to Genesis™509 and Genesis™ 510. Less
- tolerant than Genesis™ 836.
- Sow high quality seed at rates calculated to achieve 40 to 50 plants/m2 establishment.
- Target the optimum sowing window for desi chickpeas in your region, but avoid very early sowing (to minimise the risk of lodging).
- Inoculate with Group N Chickpea Rhizobium.
PBA StrikerA has not shown any sensitivity to a range of recommended pre- and post-emergent herbicides applied at recommended rates.

PBA Striker is a standard ‘Indian’ type desi chickpea and has been assessed as suitable for both splitting and direct consumption use by traders in India and the Middle East. It is larger in size than PBA Slasher and similar in seed colour.
PBA Striker has excellent milling quality, as measured by dhal yield (%), and is better than Genesis™ 509, Genesis™ 510 and Genesis™ 836 (2-4 % higher). The dhal has the distinct dimpling required by Indian markets to differentiate it from field pea dhal. Dhal colour of PBA Striker is very similar to that of PBA Slasher.

Data is an average of 9 sites across 3 years (2009 – 11)
PBA Striker (evaluated as CICA0603) was developed by the PBA chickpea breeding program (led by NSW Dept of Primary Industries) from a cross between 8511-14 (Howzat sister line) and the Ascochyta resistant Iranian landrace ICC3996).
