摘  要:
利用普通压片法对新铁炮百合(Lilium×formolongi)3个品种的染色体数与核型进行了分析。结果表明:(1)‘雷山1号’核型公式为2n=2x=24=4m+6sm(2SAT)+8st+6t;(2)‘雷山2号’核型公式为2n=2x=24=4m(2SAT)+2sm+10st+8t(2SAT);(3)‘雷山3号’核型公式为2n=2x=24=2m(2SAT)+8sm+4st+10t。三者核型均为3B型,其核型不对称系数分别为72.96%、77.39%和75.93%。

摘  要:
The chromosome number and karyotype studied by squash method.The results indicated that the karyotype formula of three cultivars of Lilium × formolongi as follows:(1)The karyotype formula of'Raizan 1'was 2n = 2x = 24 = 4m + 6sm(2SAT)+ 8st + 6t;(2)The karyotype formula of'Raizan 2'was 2n = 2x = 24 = 4m(2SAT)+ 2sm + 10st + 8t(2SAT);(3)The karyotype formula of'Raizan 3' was 2n = 2x = 24 = 2m(2SAT)+ 8sm + 4st + 10t.The three cultivars of karyotype belonged to 3B,asymmetry index(As.K%)were 72.96%,77.39%,75.93% respectively.
