摘　　要：为掌握引进芫荽种质资源遗传情况,选用23条引物对96份芫荽资源进行分析,在此基础上分析其遗传多样性与性状之间的关联。结果表明,供试群体的Simpson指数为0.098~0.505,Shannon指数为0.085~0.301,种质特异指数为69.964~208.694。53个RAPD标记中有17个标记与15个性状相关联。与抽薹天数(DSE)、始花期(DSF)、终花期(DEF)、收获天数(DH)、最长基生叶长(LLBL)、花期(FR)、茎中花青素(ANST)、株高(PH)、基生叶数(NBL)、植株有叶状态(LP)、基生叶生长习性(HBL)、分枝数(NB)、果实形状(SF)、千粒重(W1000F)和果实裂果趋势(TSF)关联的多态性位点分别有1、2、2、2、2、3、2、2、2、2、4、2、6、2和2个。其中,4个位点同时与两个或2个以上性状相关联。In order to understand the genetic information of the introduced Coriander germplasm resources,23 random primers were selected for the polymorphism detection of 96 materials,and the relationship between genetic diversity and traits was analyzed.The results showed that the Simpson's index of the population was 0.098~0.505,and the shannon's index was 0.085~0.301,and the specialty index was 69.964~208.694.17 of the 53 RAPD markers were associated with 15 traits.The numbers of polymorphic markers associated with days with convulsions(DSE),initial flowering stage(DSF),flowering stage(DEF),days of harvest(DH),longest basal leaf length(LLBL),flowering stage(FR),anthocyanins(ANST),strain High(PH),basal leaf number(NBL),plant leafy state(LP),basal leaf growth habit(HBL),number of branches(NB),fruit shape(SF),1000-grain weight(W1000F)and fruit cracking Trend(TSF)were 1,2,2,2,2,3,2,2,2,2,4,2,6,2 and 2.Among them,4 sites are associated with two or more traits at the same time.
