【Abstract】 Chinese radish (Raphaus sativus L. Subsp. hubernus Alef.) was originally grown in China. Its cultivation commenced more than 2,000 years ago.After a long period of cultivation and selection, various good types of radish were pro-duced in different regions. According to their reaping seasons, they are classified by the Agricultural Academy of China into four seasonal types: the all season radish, the spring radish, the summer-autumn radish and the winter radish. The winter radish is the most im-portant, since its yield is the highest.Regional assignment of radish production in China may be of much value in the vege-table growing, breeding, and scientific research, the biological properties of the winter radish in relation with the geographical and climatical factors, the following nine growing regions are assigned:(1) the North east mid-autumn growing region; (2) the Mongolia-Sinkiang mid-autumn growing region; (3) the Chinghai-Tibet mid-autumn growing region; (4) the Northern part of north China and the Wei river mid-autumn growing region; (5) the central and southern part of North China late autumn growing region; (6) the mid-lower Yangtze River early winter growing region; (7) the Szechuan Basin winter growing region; (8) the Yunnan-Kwei-chow plateau; (9) the South China more chiefly multi-season growing region. The climate of the growing seasons and cultural specialities of radish are also briefly stated.更多还原
