运用１０种限制性内切酶分析了林氏果蝇（Ｄｒｏｓｏｐｈｉｌａｌｉｎｉ）来自不同地区的２２个单雌系的线粒体ＤＮＡ（ｍｔＤＮＡ）限制性片段长度多态性（ＲＦＬＰ）。采自台湾省的ＴＡＷ３１４６．１与大多数采自广东的品系相同；而广东省品系中则存在一定程度的分化，ＤＨＳ３０７、３１５和ＮＫＳ９２３４仅在ＨｉｎｄⅢ的酶切位点上与其余单雌系不同；ＴＡＷ３１４６．１与来自缅甸中部的ＭＭＹ３０７，ＭＭＹ３２６之间的遗传距离为０．００２７４；ＭＭＹ３０７与ＭＭＹ３２６之间无差异；ＴＡＷ３１４６．１与来自缅甸南部的ＲＧＮ３，ＲＧＮ２０６的遗传距离分别为０．００５３４和０．００５５３；ＭＭＹ３０７，ＭＭＹ３２６与ＲＧＮ３，ＲＧＮ２０６则分别为０．００８３５和０．００８６８。ＲＧＮ３、２０６的分化较为明显。这一结果与生殖隔离测试的结果基本一致
Ten restriction enzymes were used to analyze mitochondrial DNA restriction fragment length polymorphism (RFLP) of 22 hermaphrodite lines from different regions of Drosophila Linn. TAW3146.1 from Taiwan province is the same as most strains from Guangdong; while there is a certain degree of differentiation in Guangdong strains. DHS307, 315 and NKS9234 are only different from other single herds at HindIII restriction sites ; The genetic distance between TAW3146.1 and MMY307 and MMY326 from central Myanmar was 0.00274; there was no difference between MMY307 and MMY326; the genetic distances between TAW3146.1 and RGN3 and RGN206 from southern Myanmar were 0.00534 and 0.00553; MMY307, MMY326 and RGN3, RGN206 were 0.00835 and 0.00868, respectively. The differentiation of RGN3,206 is more obvious. This result is basically consistent with the results of reproductive isolation tests
