研究用 ＲＡＰＤ技术对条斑紫菜（Ｐｏｒｐｈｙｒａ ｙｅｚｏｅｎｓｉｓ）、坛紫菜（Ｐ． Ｈａｉｔａｎｅｎｓｉｓ）。半叶紫菜（Ｐ．Ｋａｔａｄａｉ ｖａｒ． Ｈｅｍｉｐｈｙｌｌａ）和少精紫菜（Ｐ．Ｏｌｉｇｏｓｐｅｒｍａｔａｎｇｉａ）的１５个无性系丝状体进行了遗传多样分析，用１２０个Ｏｐｅｒｏｎ引物进行了筛选，从中选用来自ＯＰＪ－１８和ＯＰＮ—０２扩增出的８条多态性条带构建了这１５个紫菜无性系的ＤＮＡ指纹图谱，在该图谱中每个紫菜无性系均有各自特异的ＤＮＡ指纹．用１和０分别表示ＤＮＡ带的出现和缺失，将各个无性系的ＤＮＡ指纹用计算机语言表示，建立了１５个紫菜无性系的计算机化ＤＮＡ指纹；在此基础上设计了紫菜无性系种质鉴定的计算机软件ＰｈＧＩ．
To study the effects of RAPD on Porphyra yezoensis and P. haitanensis. Fifteen clonal filaments of P. Katatai var. Hemiphylla and P. Oligospermatangia were genetically diversely analyzed using 120 Operon primers from which OPJ-18 and The 8 polymorphic bands amplified by OPN-02 constructed DNA fingerprinting of these 15 laver clones, and each laver clone had its own DNA fingerprinting in this map. The presence and absence of DNA bands were represented by 1 and 0, respectively. The DNA fingerprints of each clone were expressed in computer language and computerized DNA fingerprints of 15 laver clones were established. Based on this, the germplasm identification of laver clones was designed Computer software PhGI.
