Abstract

Abstract

Genetic variation of 11 lines of Porphyrayezoensis from the coast seas of Kagoshima (Japan),Qingdao,Nantong,Putuo and Naiji islands were studied by using amplified fragment length polymorphism (AFLP).778 bands are obtained with AFLP analysis of 16 primer combinations,among which 15 are unique,about 98.07% are polymorphic.The AFLP data show that the closest genetic distance are 0.180 between two Kagoshima samples,and the furthest one 0.397 is between Kagoshima No.1 line and Nant ng No.9 line.The genetic distance shows that the variation is within the inner species scope.Neighborjoining cluster and UPGMA cluster indicate that samples from Kagoshima and Qingdao were with high similarity and either with the samples of Nantong,Putuo and Nanjiislands.Porphyrayezoensis in China shares high genetic diversity,and the genetic distance shows positive correlation with the geographic distance.
