Early detection of the level of resistance or susceptibility to Ganoderma boninense is of paramount importance for the sustainability of the oil palm industry particularly in SouthEast Asia.

Currently more than 1000 crosses have been tested at least two times in independent trials for their resistance/susceptibility level to Ganoderma.

Abstract

Early detection of the level of resistance or susceptibility to Ganoderma boninense is of paramount importance for the sustainability of the oil palm industry particularly in SouthEast Asia. A nursery Ganoderma screening method has been developed and validated in collaboration with two Indonesian private companies PT PP London Sumatra Indonesia TBK Lonsum and PT Socfin Indonesia Socfindo to improve the resistance of their commercial planting material to Basal Stem Rot BSR disease. This early routine prenursery screening test involves the exposure of germinated seeds from different oil palm progenies with Ganoderma-colonized Rubber Wood Blocks RWBs. Over the last two years the potential testing capacities have been developed in both companies to allow the routine screening work of one hundred crosses per month. Currently more than 1000 crosses have been tested at least two times in independent trials for their resistance/susceptibility level to Ganoderma. The screening method described in this paper is rapid and easy to set up in the prenursery and limits the sources of variability. Each step of the method has been previously studied calibrated and standardized in order to reach this level of consistency. Nursery results compared with field results showed a good correlation. This test therefore provides a method to ensure no highly-susceptible progenies are transferred to the field for commercial planting provides a breeding tool to develop more Ganoderma tolerant high yielding planting material to understand the genetics of Ganoderma tolerance/susceptibility to investigate Ganoderma infection and as a more general tool to test other methods to control and prevent Ganoderma.
