Eighty－seven strains of Er2vinia caTotowora subsp ． carotovora （Ece ） isolated from various host plants in several geographie regions of Asia during differe，nt years ， were characterized by their fatty acid compositions ． All strainS contained ， in ciecreasing order of amount present ， laumic acid （12：0） ， palmitic acid （16：0） ， palmitoleic acid （16：1 cds 9） ， vaccenic acid （18：1 cis l l ） and one unideRtified fatty acid （Uft一一3） ． Also present in seme but not all sも舳swere ca麟餓。…d（1◎：◎），翼晦sも圭 。 addσ4：◎），3－kydr◎xy圭a題。翫dd（12：◎3－0｝翼） ， s乞e麟c aci｛1（18：◎），蓋難《）蓋e重（｝ae董d（18：30露9，王2）ε膿d薮）ur 1癒（艶難も盗e（匪鍛もζy aci（孟s（UR－i，Un－2 ， U轟＿4 a澄d Un－5） ． ln cluster analy＄is based◎R the fatty ac童d c◎mpositi◎n，撒e Ecc sもra無s聡re co即◎sed of two groups （1 and ff） ． WheR the strains were grouped according to their geographical origins， some relationships were found ． All Korean and most of Thai strains be｝onge．d to the group fi， while Japanese isolates belonged to the both grou．ps
