Possibility of inter-generic, inter-specific and inter-varietal grafting in Cruciferae was studied. The grafting was succeeded in the following combinations, i.e., cabbage / kale (scion / rootstock), kohlrabi / kale and cabbage / kohlrabi in Brassica oleracea and Chinese cabbage / turnip in B. campestris in inter-varietal grafting, Chinese cabbage / kale, Chinese cabbage / cabbage, Chinese cabbage / Takana (B. juncea) and Takana / turnip in inter-specific grafting among B. oleracea , B. campestris and B. juncea, and Chinese cabbage (B. campestris) / Japanese radish (Raphanus sativus) and Japanese radish / cabbage (B. oleracea) in inter-generic grafting. Survival ratios of these successful grafts were low (from 5% to 20%), because the seedlings for scion and rootstock were too small to handle. Cavities were observed at the demarcation zone between scions and rootstocks, when thickening was alternatively observed in scion or rootstock. In the Chinese cabbage / turnip graft, the growth of taproot was suppressed after the beginning of head formation.

Consequently, some possible combinations for grafting in Cruciferae were found. These results will be useful for the application of grafting instrument to leafy vegetables.
