The observations (1990-1992) concerned the cultivation of Japanese daikon in field conditions near Cracow. Two radish cultivars Tokinashi and Minowase Summer Cross F1, sown in June and July, reached harvest maturity after about 60-80-day growing periods without significant bolting. Tokinashi formed smaller storage roots than Minowase Summer Cross. The mean crops of daikon's marketable roots were 556 dt/ha (Tokinashi) amd 719 dt/ha (Minowase). The Japanese radish proved to be very resistant to sponginess, which appeared to be its great advantage. On the other hand, it showed a significant tendency to develop deformed storage roots and extreme vulnerability to cabbage fly invasion. A properly prepared soil as well as a suitable protection against pests seem to be of considerable importance in Japanese radish cultivation.
