以１８个豌豆栽培品种及野生种材料为ＤＮＡ样品来源，采用７个１０碱基随机引物进行ＰＣＲ扩增。基因组ＤＮＡ的多态性，利用ＲＡＰＤ标记鉴定其品种间及品种内的遗传变异性。７个引物共扩增出６６位点，其中多态性位点５６个，占８４．８％。每个ＰＣＲ扩增产物分别以０和１记录存在与否。扩增产物间成对比较产生非相似性矩阵（Ｊａｃｃａｒｄ相似系数表），此矩阵用于构建遗传相似性的树状系图谱（遗传树）。通过遗传树的构建将１０个Ｐ．ｓａｔｉｖｕｍ与８个Ｐ．ｆｕｌｖｕｍ群居为截然不同的两大组。
Eighteen pea cultivars and wild species were used as DNA samples. Seven 10-base random primers were used for PCR amplification. Genomic DNA polymorphism, the use of RAPD markers identified within the varieties and within the genetic variability. Seven primers amplified a total of 66 loci, of which 56 polymorphic loci, accounting for 84.8%. Each PCR amplification product was recorded as 0 and 1, respectively. Pairwise comparisons of amplified products result in a non-similarity matrix (Jaccard similarity coefficient table), which is used to construct a dendrogram (genetic tree) of genetic similarity. Through the construction of the genetic tree 10 P. sativum with 8 P. Fulvum is divided into two distinct groups.
