     Abstract Southern stem rot caused by Sclerotium rolfsii is an important problem in Jerusalem artichoke production in Thailand. Chemical control is not suitable to suppress the disease because chemicals can contaminate the crop. The use of host plant resistance is the most appropriate means to control the disease. Screening of Jerusalem artichoke for resistance to S. rolfsii will be much easier and effective if resistance at seedling stage is correlated with resistance at adult stage. Two plant ages at seedling stage (20 days after transplanting (DAT)) and at mature stages (85 DAT) were assigned as main plots, and 10 genotypes of Jerusalem artichoke were assigned as sub-plots in split-plot design with four replications for two years. Data were recorded for lesion length, disease incidence, days to permanent wilting and area under disease progress curve (AUDPC). The results showed that some genotypes exhibited resistance at seedling stage but they were not resistant at adult stage. The correlations between seedling and adult stages were low for all traits. JA 98 took a longer time to permanent wilting and had lower AUDPC at seedling and adult stages. JA 6 had lower disease incidence at seedling and adult stages.
