Investigation on evaluation of nine genotypes of Tuberose (Polianthes tuberosa) with respect to growth and flowering parameters were carried out under valley conditions at HNBGU, Srinagar Garhwal, Department of Horticulture, during 2013-14. The genotypes were studied for various vegetative, floral and bulb yielding attributes. Results revealed that there was a significant variation among the genotypes for various attributes. Out of the nine genotypes studied, Genotype Subasini (G9) recorded to have maximum plant height (56.00 cm), leaf area (51.71cm2), maximum number of sprouts (9.26) per plant, fresh weight of spike (123.47 g) and highest yield of spike (1.11 kg) per plot, vase life (14.22 days) and regarding bulb yielding attributes genotype G5 (Vaibhav) have maximum bulb diameter (1.77 cm) and bulb length (4.78 cm) Keeping all these parameters in view, it may be concluded that genotype Subasini is suitable for cultivation in the valley conditions of Garhwal region followed by Vaibhav and Kalyan Single.
