  The study is focused to establish an improved salt and drought tolerant Picrohiza kurroa Royle ex Benth, an endangered medicinal plant of Western Himalayas through mutagenesis system in conjunction with in- vitro regeneration technique. Regeneration using leaf as explants from mature plant of characterized germplasm is beneficial because the source plant is not damaged. Efficient callus formation i.e., 85% was achieved in modified MS medium at 2,4-D at 3.5 mg L-1. Ethyl methane sulfonate (EMS) a chemical mutagen was used to induce mutation in the callus biomass under in-vitro condition. Relatively decreases in callus biomass were observed as the dose of mutagenic chemical increased from 0.0 to 0.8 mM. Selection of mutants callus lines were also investigated against salt (NaCl) and drought (mannitol) tolerance level by using its various concentrations i.e., 50 to 250 mM L-1. In mutagen.. View More»
