Abstract: Catamixis baccharoides (Family: Asteraceae), is a chasmophyte shrub and is endemic to Garhwal and Nepal only. Indole-3-Butyric Acid (IBA) concentration treatments were tested around 5000 ppm concentration i.e. 4000 ppm, 5000 ppm, 6000 ppm and 7000 ppm concentrations to enhance rooting and plant percentage. Twenty cuttings of each germplasm were planted in four replications. The rooting among the two germplasm collections in Catamixis baccharoides fluctuated between 43.8%and 57.5% for IBA concentration of 4000 ppm to 7000 ppm. The plant percentage ranged from minimum 41.3% to maximum 48.8%. The performance of 4000 ppm was significantly lower than 6000 ppm for both germplasm collections. Thus, 6000 ppm can be effectively used for propagating this species for future conservation.
