Abstract
Valeriana jatamansi Jones is a natural tetraploid species indigenous to the Indian Himalaya. To assess its genetic diversity and population structure, we analyzed six natural populations from the western Himalayan region using amplified fragment length polymorphism. An analysis of molecular variance found that 93% of the genetic variation of V. jatamansi was within populations and 7% among populations. The correlation between genetic and geographic distances (r = 0.14) was not significant. Though the populations are well separated, the lack of distinct genetic variation between populations may be due to either recent rapid fragmentation from a wide and continuous area resulting in genetically similar populations or wide dispersal of seed by wind, since the follicles are feathery. Polyploidy may be the reason for the lack of genetic impoverishment due to fragmentation.Keywords
