中国栽培大豆代表品种和野生大豆部分群体脲酶等位酶的分析

用聚丙烯酰胺凝胶电泳方法分析了我国栽培大豆８２个代表品种和野生大豆部分群体的脲酶等位酶。本实验室条件下脲酶快带Ｒｆ＝０．５４－０．５９，慢带Ｒｆ＝０．３６－０．４３，与文献报道一致。所分析８２个品种快慢脲酶变异体约各半，各等位的分布与该品种的产地无上关性。在已分析的野生大豆群体中，也发现脲酶存在快带和慢带两种变异。所以大豆脲酶基因的突变可能发生在野生大豆的天然群体里。

ANALYSIS OF UREASE ALLOZYMES OF CHINESE SOYBEAN CULTIVARS (GLYCINE MAX)ASD SOME NATIVE GROUPS OF WILD SOYBEAN (C. SOJA)

The urease isozyme variation of 82 representative cultivars of cutivated soybeans and some native groups of wild soybean in China were analysed by using of polyacrylamide gel electrophoresis.The Rf values are 0.36 - 0.39 for slow variant and 0.54 - 0. 59 for fast variant which agree with the values reported in literature.Allelic variation of Eul has been found among native groups and within groups of wild soybean.Therefore,the mutation of soybean usease may occur in natural populations of wild soybean.
