The inoculation concentration and three methods were studied in Ceretocystis paradoxa which caused coconut stem bleeding disease.The results indicated that spraying method with spores suspension and mycelial plug method were the proper inoculation methods.The best inoculation concentration were 3.2 x 105 spores · mL-1 , and the inoculated mycelial plugs with white color were cultured for two days.The resistance identification of 6 coconut resources with spraying method on the coconut leaves, coconut and leave stalks.The result showed none of them were resistant to the pathogen Ceretocystis paradoxa, but the disease situations were not the same, the incidence rate of Wen-coconut 78F1was the slowest, Red Dwarf Coconut was the second.The screening results showed that the inoculation method and screening method were stable and efficient.
