摘　　要：采用地理分布方法研究我国萝卜品种现状,结果表明:栽培萝卜品种和不完全显性性状主要分布在第Ⅲ栽培区(山东省、江苏省、安徽省及河南省)。通过分析酯酶同工酶酶谱及萝卜肉质根颜色性状变异最大的地区,表明第Ⅲ栽培区属于遗传变异中心。根据上述理由,依据瓦维洛夫的观点初步推断萝卜起源于黄淮平原和山东丘陵一带。With the aid of phytogeographic method,the frequence distribution of 1361 Chinese radish varieties and incomplete dominant character were ana- lysed.Three cultivated areas(Shandong,Jiangsu,Anhui,and Henan provinces) were determined as regions where the heritable form of species and the geogra- phic centre occurs the basic varifies are concentrated.It also has been ascer- tained as the centre of genetic divesity for colour character of radish rood and esterasc isozyme genotype.According to Vavilov idea,China was infered as the centre of origin of cultivated radish,at least the second one.The Chinese radish exactly origined from the Yellow and Huai River valley plain and Shan- dong mountainous district.Two years'cultivated test of 120 different radish varieties indicated that the diversity of botanical character of Chinese radish is abundant and radish Climate ecotype is divided into northern cold-dry eco- type,southern warm-moist ecotype.Archeological,historical and linguistic data have been examined in order to understand the cutivation,propagation of radish and the climate of ancient yellow river valley was warmer and moister than that of now.
