Himalayan Gentian (Gentiana kurroo Royle) a member of family Gentianaceae, is a critically endangered perennial herb of high medicinal and ornamental value. About 80 percent of its geographical range lies in India, particularly in the North Western Himalayan states of Jammu & Kashmir, Himachal Pradesh and Uttarakhand. The species is under threat due to loss of habitat, destructive harvesting for roots and rhizomes and climate change. Naturally, the species propagates through seeds. Seed germination studies revealed that freshly harvested seeds fail to germinate promptly. Seeds loses viability and hardly germinate after one year. After two to three months of seed collection seed germination was 79.01 per cent in lab conditions. Cold stratification at -5±2°C for three months and treatment with 60 ppm GA3 solution were comparable and improved germination to 91 percent and 95 percent respectively. Soil from natural habitat recorded to be preferred growing media followed by sandy loam soil and mix of soil + sand + FYM (1:1:1). Seedlings at two leaf stage be transplanted in ploy bags for higher field survival. Seedlings exhibited field survival of 75 percent. Plant divisions gave 54.80 percent field survival. Shoot cuttings treated with 500ppm IBA gave 84.96 per cent field survival. The multiplication through seeds and shoot cuttings may help in conservation of species through enrichment of existing populations in natural range and bringing the species under cultivation to meet its market demand.
