Abstract:
Genetic diversity of Ap ocy num venetum was studied by the m ethod of random amp lified polym orph ic DNA ( RAPD) in this paper. Out o f 9 w ild popu lations from 8 prov inces o f Ch ina, 157 bands we re produced w ith 17 random pr im ers and 108 of them w ere po lym orphic. A t spec ies leve,l its po lymo rph ic lo ci percentage, N ei’s genetic d iversity index and Shannon’s in fo rm ation index w ere 68.79%, 0. 229 6 and 0. 339 0 respectively. The tota l gene d ifferen tiation ( G st) ofA. venetum w as 0.884 1. Th is ind icated that 881 41% o f genetic var iation res ided am ong popu lations and genetic va riation among populations w asm uch h ighe r than thatw ithin popu la tions. Results from genetic d istances and cluster ana lys is showed that relationsh ips am ong populations was not comp le tely co rre lated w ith their geog raph ica l d istances. According to the current genetic d iversity s ituation o fA. venetum, protec tion of natural population w as suggested to be streng thened.
