Molecular Markers For PCN Resistance
The discovery of Potato Cyst Nematode (PCN) in Western Australia in 1986 and Victoria in 1991 has resulted in breeding for resistance to PCN becoming an objective of the National Potato Improvement and Evaluation Scheme (NaPIES). This work has shown that the molecular marker system based on CP113 cannot be readily applied to NaPIES for the routine screening for PCN. Preliminary evaluation of the CD78 marker found it potentially useful. Further work is warranted but only if breeding for PCN resistance becomes a priority of the NaPIES rather than an objective.
