Valeriana jatamansi is an important medicinal plant found in the Western Himalayas which is increasingly decreasing in its natural habitats due to its overexploitation for medicinal uses. Therefore study was conducted to identify promising populations and commercially viable morphotypes for cultivation of the species for reducing the pressure on the natural populations. In this study, the plants of Valeriana jatamansi were collected from ten natural populations from Tehri and Dehradun districts and their rhizome cuttings were planted in the protected as well as in field condition. The plants showed maximum survival (93.3%) in Kempty population (1391 m elevation) under protected condition, survival was obtained 80% in Kwava , Nagthat and Buranskantha accessions under field condition. In comparison to field condition, growth performance was also observed better under protected conditions like fresh (16.47g) and dry weight (1.66g) of shoots in Mathyau population, roots fresh (7.52 gm) and dry weight (1.05gm) in Kwawa population whereas in field condition, yield of fresh shoot was obtained better in Nagthat population and fresh roots weight it was good in Buranskandha accession. The dry shoot weight was recorded in Zero point population and dry roots weight was registered maximum in Nagthat population under field condition. On the basis of morphological studies promising morphotypes have been identified as Mathyau, Kwawa, Nagthat and Buranshkanda populations which can be used for further studies of genetic and phytochemical characters to isolate stable and distinct morphological features.
