Abstract
This paper gives the results of nursery experiments performed with Jerusalem artichoke seedlings. A small number of seeds were obtained at natural condition or glasshouse in Kyushu. The seeds were sown in the sand soil bed of glasshouse, and seedlings were transplanted in the field. All seedlings producted tubers, and the variability of weight, number and stolon length of tuber was very wide. It might be possible to breed Jerusalem artichokes from seedling at natural condition in Kyushu.
