Abstract:
Genetic div ers ity o f aw ild populations and a cu ltured population o fElop ichthys bambusa w as investiga ted using amp lified fragm ent length po lym orphism ( AFLP). Thew ild popu lation w as co llected from Suzhou area of Yang tze R iver and the cultured popu la tion w as hatche ry- reared o ffspr ing o f w ild caugh t ind iv idua ls from the sam e area. S ix EcoR I and M seI prim er com bina tions produced 47 po lymo rph icma rkers out o f the tota l o f 313 bands am plified from 47 tota l ind iv iduals. The propo rtions of po lym orph ic loc i o f thew ild popu lation and the cu ltured population were 13142% and 8131%, respectiv ely. These Shannon. s inform ation index and average hete rozygosity w ere 01054 and 01 032, 01 341 and 01199, respectiv ely. The resu lts show ed that there was a little differentiation in the g enetic d ive rsity index o f these two populations. Gst va lue and Shannon. s inform ation index indicated that there w as som e genetic differentiation be tw een populations. The UPGMA tree based on AFLP data suppo rted this resu lt. In th is pape r, the results of AFLP analysis ind ica ted tha t two popu lations o f E. bam busa presented low er gene tic dive rs ity. M o reover, som e gene tic d iffe rentiation were showed be tw een two populations, and the cu ltured population w illm aybe form stab le owe gene tic structure by mu lt-i g ene ration a rtific ia l breed ing.
