| 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。 |

| Abstract: |
| 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... |
