Morphobiochemical Variability and Selection Strategies for the Germplasm of Dactylorhiza hatagirea (D. Don)‎ Soo : An Endangered Medicinal Orchid

Abstract EN

Dactylorhiza hatagirea (D.

Don) Soo (Orchidaceae) is an important endangered medicinal herb, distributed in subalpine to alpine regions of the Himalayas.

Its tubers are important constituents of many medicines and health tonics.

Overexploitation for medicinal uses has decreased availability in natural habitats and this species has been enlisted as endangered, making conservation and cultivation studies necessary.

Variability studies may serve as an important tool for effective conservation and for a crop improvement program.

Therefore, natural populations of D.

hatagirea were analyzed for variability on the basis of morphological, biochemical, and isoenzyme patterns.

The studied populations were grouped into two clusters.

Existing variability among different populations opens up new areas for conservation and perspectives for a genetic improvement program for D.

hatagirea.
