Chickpea Phytophthora root rot – 2015 varietal rankings and yield losses locations
Aims

To evaluate a range of varieties and advanced PBA breeding lines.

Phytophthora medicaginis, the cause of phytophthora root rot (PRR) of chickpea is endemic and widespread in southern QLD and northern NSW, where it carries over from season to season on infected chickpea volunteers, lucerne, native medics and as resistant structures (oospores) in the soil.  Although registered for use on chickpeas, metalaxyl seed treatment is expensive, does not provide season-long protection and is not recommended.  There are no in-crop control measures for PRR and reducing losses from the disease are based on avoiding risky paddocks and choosing the right variety.

Detailed information on control of PRR in chickpea is available at:

http://www.pulseaus.com.au/growing-pulses/bmp/chickpea/phytophthora-root-rot

Current commercial varieties differ in their resistance to P. medicaginis (Pm), with Yorker and PBA HatTrick having the best resistance and are rated MR (historically Yorker has been slightly better than PBA HatTrick), while Jimbour is MS - MR, Flipper and Kyabra are MS and PBA Boundary has the lowest resistance (S).

From 2007 to 2015 PRR yield loss trials at the DAF Qld Hermitage research Facility, Warwick QLD have evaluated a range of varieties and advanced PBA breeding lines. 

Key messages

Key findings:

  • In a wet season, substantial yield losses (94%) from Phytophthora root rot (PRR) occurred in susceptible chickpea varieties such as PBA BoundaryA.
  • Varieties with improved resistance to PRR (PBA HatTrickA and YorkerA) can also have large yield losses (68–79%) in a season highly conducive to PRR.
  • Although yield losses will occur in seasons highly conducive to PRR, crosses between chickpea and wild Cicer species, such as the PBA breeding line CICA1328, currently offer the best levels of PRR resistance.

Summary

Under conditions that are highly conducive to PRR, substantial (94%) yield losses occur in susceptible varieties such as PBA Boundary.  However, significant losses (68-79%) can also occur in varieties with improved resistance to PRR (PBA HatTrick and Yorker).  Crosses between chickpea and wild Cicer species such as the PBA breeding line CICA1328 offer the best resistance to PRR.

Disease and yield loss prediction: Yield loss caused by PRR calculation

  • All plots inoculated with Pm at sowing
  • PRR level manipulated with and without the fungicide metalaxyl
  • Three replicates

% loss = 100*(Average yield of metalaxyl-treated plots – Average yield of nil metalaxyl plots)/Average yield of metalaxyl-treated plots

Variety: PRR protection

Seven genotypes:

CICA0912, CICA1007, CICA1328 (=D06318>F3BREE2AB016), D06344>F3BREE2AB027, PBA Boundary, PBA HatTrick, Yorker

Two treatments,

(i) seed treatment with thiram, thiabendazole and metalaxyl plus regular soil drenches with metalaxyl

(ii) seed treatment with thiram + thiabendazole only with no soil drenches
