Data from: Cytoplasmic DNA variation and biogeography of Larix Mill. in Northeast Asia
Range-wide variation in 54 populations of Dahurian larch (Larix gmelinii) and related taxa in Northeast Asia was assessed with four mitochondrial PCR-RFLP and five chloroplast SSR markers. Eleven mitotypes and 115 chlorotypes were detected. The highest diversity was observed in the southern Russian...
