摘要

Basal stem rot (BSR) is one of the most serious diseases of oil palm and the incidence could be as high as 25 per cent (Singh, 1991; Ariffin et al., 2000). In India, the disease is caused by either G. lucidum or G. applanatum (Anonymous, 2008). Crossinfectivity of this pathogen is already reported (Turner, 1981; Mandal et al, 2003) and the BSR occurrence in oil palm in India is noticed where under planting is done in the infected coconut gardens. The disease is rapidly spreading in the oil palm growing states of India. One of the major problems associated with this disease management is the lack of early diagnosis. By the time symptom appears, the palm is beyond recovery. If early identification of infected palms was impossible, they can be treatedand the disease can be managed effectively. Hence an early detection technique is felt essential for effective management of basal stem rot in oil palm.Ganoderma is a soil borne fungi under the family of Ganodermataceae, which mostly cause infection through the root. Hence the inoculum can be detected first in the root than from any other part of the palm. In the present study, a PCR based confirmatorydiagnostic technology for detection of Ganoderma has been attempted using the root samples of oil palm.
