采用聚丙烯酰胺凝胶电泳的方法,对花生属植物10个栽培种和10个野生种的酯酶同工酶谱带进行测定分析。根据酶谱的差异,栽培种花生与花生区组野生种的平均相似值为12.93％,与其他区组相比其相似值高。表明两者间亲缘关系较近,从生化测定证实了花生区组的野生种是栽培种的近缘祖先的推断。另外,结果表明不同类型的栽培种与花生区组的各个野生种的亲缘关系也存在差异,其中以珍珠豆型品种与A.durenesis的关系最近。 By using polyacrylamide gel electrophoresis, the esterase isozyme bands of 10 cultivars and 10 wild species of peanut were determined. According to the difference of zymogram, the average similarity of cultivated peanut and peanut wild species was 12.93%, which was similar to other groups. Which indicates that the genetic relationship between the two is close. The biochemical analysis confirmed that the wild type of peanut group is the ancestor of the cultivated species. In addition, the results showed that different types of cultivars and peanut groups of wild relatives of different species there are differences, of which pearl bean varieties and A. durenesis the relationship.
