Abstract
Drug yielding potential of turmeric (Curcuma longa L.) is due to the presence of important phytocon- stituents such as curcumin, oleoresin and essential oil. Slow multiplication rate, high susceptibility to rhizome rot and leaf spot disease and restricted availability of elite genotype necessitated application of tissue culture tech- nique to alleviate the problems. A protocol has been developed for in vitro micropropagation of an elite geno- type (cv. suroma) using latent axillary bud explants from unsprouted rhizome, available throughout the year. MS media containing 3 mg/l 6-Benzyladenine (BA) and 1 mg/l Indole Acetic acid (IAA) was found optimum for regen- eration, multiplication and in vitro conservation of plant- lets. After 3 years of in vitro conservation regenerants were transplanted to field and assessed for drug yielding poten- tial through evaluation of curcumin, oleoresin and essential oil contents of rhizomes and leaves. One year of field grown tissue culture derived turmeric were found uniform in all the characteristics examined, when compared with those grown conventionally. Micropropagated turmeric showing stable drug yielding potential also proved to have genetic basis of stability as revealed by RAPD based molecular profiling.
