| Abstract:
A replicated field evaluation trial was conducted involving 13 accessions of Coleus forskohlii Briq. (Lamiaceae), a forskolin yielding aromatic herb with fasciculate tuberous roots. Forskolin (diterpenoid) is used for treatment of glaucoma, cardiomyopathy and certain cancers. Significant differences were recorded for all the characters except dry mass of roots. Maximum tuber number per plant (12.0) was in IIHR-59. Accession IIHR-59 also produced highest fresh and dry mass of tubers (870 g and 88.75 g, respectively) per plant. The harvest index was maximum (45.1%) in IIHR-80. The forskolin content was estimated using HPLC and was found to vary from 0.025 per cent (IIHR-1) to 0.798 per cent (IIHR-12). Forskolin yield per plant was highest in IIHR-7 (85.00 mg). The accession IIHR-80 with medium tuber yield and higher forskolin content (0.715%) can be promoted for commercial cultivation as the crop is propagated through vegetative means. | |
