Abstract
Investigations were carried out to evaluate the medicinal coleus [Plectranthus forskohlii (Willd) Briq.] genotypes for growth, tuberous root yield and suitability for pickling at the Department of Plantation, Spices, Medicinal and Aromatic Crops, Kittur Rani Channamma College of Horticulture, Arabhavi during 2012- 2013. The experiment was conducted in a Randomized Complete Block Design having three replications and ten medicinal coleus genotypes collected from different geographical locations. The main objectives of the study was to find out superior genotype for tuberous root yield and suitability as condiment. Among the genotypes evaluated for growth parameters maximum plant height (69.40 cm) was recorded in KRCCH-7, while highest plant spread (11,859.47 cm2) was observed in genotype KRCCH6, highest stem diameter (2.90 cm) in KRCCH-4, highest total number of branches (75.74) and number of leaves per plant (237.33) in KRCCH-6 , highest petiole length (2.31 cm) in KRCCH-5 was observed at harvest.
Among the yield parameters, highest number of tubers per plant (20.20) was recorded in KRCCH-7, highest tuber length (20.68 cm) and tuber diameter (2.51 cm) in KRCCH-8. The highest fresh weight of tubers (417.67 g) was observed in KRCCH-1, highest dry weight of tubers (56.05 g) was observed in KRCCH-3. The highest tuber yield (15.31 t) in KRCCH-5, highest total dry matter accumulation per plant (205.20 g) was observed in KRCCH-2. Among the genotypes evaluated for use as condiment, KRCCH-5 was found to be highly suitable.
