The effects of the soil and weather conditions of Uwaba highland on the yield and quality of Chinese red radish were investigated in 2005 and 2006. In both years, the Chinese red radish 'Xin li mei' showed a good growth under the soil and weather conditions of Uwaba highland. Fresh weight of root of Chinese red radish was 260g, about one third of a normal Japanese radish. The yield of 4200kg per 10a in two year average was smaller than a Japanese radish 'Akibare', which yield was 6200kg per 10a. However, the plant density of 'Xin li mei' was twice as high as that of 'Akibare'. Suger content of 'Xin li mei' was 1.3% higher than that of 'Akibare'. A type of polyphenol contents of 'Xin li mei' was more than double of those of 'Akibare'. These results indicate that Chinese red radish is suitable for the cultivation in Uwaba highland, and are expected to be a staple food of this area.
